A nurse is caring for a client who was admitted 72 hours ago for a severe respiratory infection. The client suddenly becomes extremely agitated, exhibits profuse diaphoresis, and frantically states, "There are spiders crawling all over the walls!" The client's spouse reports that the client usually drinks a pint of vodka daily but abruptly stopped on the day of admission. Arrange the following nursing actions in the correct prioritized sequence from first to last.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence is to first remain with the client and call for help, followed by assessing airway and vital signs, then administering the intravenous benzodiazepine, establishing bedside seizure precautions, and finally decreasing environmental stimuli.
The sequence follows standard NCLEX prioritization frameworks: Safety first (calling for help while staying with the client), followed by the Nursing Process (assessing vital signs before intervening), followed by Maslow's Hierarchy of Needs (treating the acute physiological threat with medication, preparing for physiological complications like seizures, and finally addressing the environmental/psychosocial needs).

Step-by-Step Solution

1
Ensure immediate safety (Remain with the client and call for assistance).
The client is protected from sudden self-harm and additional staff are available to assist.
In acute delirium tremens, the client is highly unpredictable. A nurse must never leave an acutely delirious and hallucinating client alone.
2
Assess physiological status (Assess airway and vital signs).
Baseline autonomic stability is evaluated.
Applying the nursing process, assessment must precede intervention to determine the extent of tachycardia, hypertension, and respiratory status.
3
Implement primary treatment (Administer IV benzodiazepine).
Central nervous system irritability is suppressed.
Pharmacological therapy is the definitive treatment for severe alcohol withdrawal to prevent progression to seizures or cardiovascular collapse.
4
Prevent complications (Verify suction and oxygen).
Seizure precautions are strictly enforced.
Even with medication, the risk of seizures remains high. Preparing the environment for a potential airway emergency is the next highest physiological priority.
5
Provide psychosocial milieu management (Decrease environmental stimuli).
Sensory triggers for hallucinations are minimized.
Once life-threatening physiological and safety priorities are addressed, calming the environment addresses the client's psychological distress.

Question 42Question →

A nurse is caring for a client who is receiving a packed red blood cell (PRBC) transfusion. Fifteen minutes after the infusion begins, the client suddenly reports severe lower back pain, chills, and shortness of breath. What is the priority sequence of nursing actions to minimize the risk of further physiological deterioration? Arrange the steps in the correct chronological order.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct priority sequence is to first stop the transfusion immediately, then maintain IV access with normal saline using new tubing, assess the client's vital signs, notify the provider and blood bank, and finally return the materials to the blood bank for analysis.
In the event of a suspected acute hemolytic transfusion reaction (indicated by lower back pain, chills, and shortness of breath), the overarching priority is risk reduction through immediately stopping the source of harm. Once the transfusion is stopped, maintaining a patent IV line with normal saline and completely new tubing is essential for administering emergency medications. Only after stabilizing the IV line should the nurse assess the client fully, followed by notifying the provider and blood bank to initiate emergency orders and investigations based on the assessment findings. Finally, the remaining blood and tubing are returned to the blood bank for procedural analysis.

Step-by-Step Solution

1
Stop the blood transfusion immediately.
The infusion of the incompatible blood product is halted.
This is the most critical step to prevent further incompatible cells from entering the client's circulation, mitigating the risk of cardiovascular collapse.
2
Disconnect the blood tubing and initiate 0.9% sodium chloride using new tubing.
Patency of the intravenous line is maintained without administering more blood.
Vascular access is needed for emergency drugs. New tubing must be used to prevent flushing residual reactive blood from the old tubing into the client.
3
Assess the client's vital signs and respiratory status.
The nurse obtains baseline data on the severity of the acute reaction.
This information is necessary to communicate the client's current physiological state to the healthcare provider so they can prescribe appropriate interventions.
4
Notify the healthcare provider and the blood bank.
The medical team is alerted to the adverse event.
The provider will prescribe interventions (e.g., epinephrine, fluids, antihistamines, corticosteroids), and the blood bank must initiate a transfusion reaction protocol.
5
Return the blood bag, attached tubing, and labels to the blood bank.
The physical evidence of the transfusion is sent for laboratory analysis.
This allows the blood bank to type and crossmatch the blood again to identify the specific error or unexpected antibody.

Question 43Question →

A nurse is removing a non-tunneled central venous access device (CVAD) from a client's right subclavian vein. Immediately after the catheter is withdrawn, the client exhibits sudden, severe dyspnea, diaphoresis, and a loud, continuous "churning" murmur over the precordium. To mitigate the risk of fatal hemodynamic collapse, arrange the following nursing actions in the priority order they should be performed. (Place the first action at the top and the last action at the bottom.)

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct priority sequence is: 1) Occlude the insertion site, 2) Position the client in left lateral Trendelenburg, 3) Administer 100% oxygen, 4) Activate the rapid response team, and 5) Ensure availability of the emergency crash cart.
An air embolism is a critical complication characterized by sudden respiratory distress and a 'mill wheel' (churning) murmur. The highest priority is to stop the entry of air by sealing the site. Following this, the left lateral Trendelenburg position uses gravity to keep the air bubble away from the right ventricular outflow tract. Administering oxygen is next to combat hypoxia and shrink the embolus. Once the client is temporarily protected from immediate death, calling for emergency assistance and preparing for a potential code are the next logical steps.

Step-by-Step Solution

1
Occlude the insertion site immediately with an occlusive dressing.
Further entrainment of air into the venous circulation is halted.
Air embolism is driven by negative intrathoracic pressure pulling air into the unsealed vein tract. Stopping the source is the single most critical intervention.
2
Place the client in the left lateral Trendelenburg position.
The air bubble is mechanically trapped in the right atrium and the apex of the right ventricle.
This prevents the air from advancing into the pulmonary vasculature, which would block blood flow to the lungs and cause immediate cardiovascular collapse.
3
Administer 100% oxygen via a non-rebreather mask.
Systemic hypoxia is mitigated and the size of the air embolus begins to decrease.
High-flow oxygen facilitates nitrogen washout from the embolus, accelerating its resorption into the bloodstream.
4
Activate the facility's rapid response team.
Advanced care providers are mobilized to the client's bedside.
After the nurse has stabilized the immediate physiological threat, medical intervention is required for definitive care (e.g., inotropes, potential aspiration of air).
5
Ensure immediate availability of the emergency crash cart.
Resuscitation equipment is placed on standby.
Despite initial interventions, a massive air embolism has a high risk of progressing to cardiac arrest, requiring immediate defibrillation and advanced airway management.

Key Concept

Management of a suspected air embolism requires immediate source control (occlusion), specific physiological positioning (left lateral Trendelenburg) to prevent pulmonary outflow obstruction, and rapid oxygenation before delaying care to summon help.
Question 44Question →

A 15-year-old client is receiving treatment in the emergency department for injuries sustained in a sports accident. The client's divorced parents are arguing loudly in the hallway outside the room regarding the proposed treatment plan, which is visibly upsetting the conscious client. In what order should the nurse perform the following actions to de-escalate the family crisis and establish boundaries? Arrange the nursing actions from first to last.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The nurse must first ensure the adolescent's emotional safety, separate the arguing parents from the clinical area, validate their feelings to de-escalate the situation, set behavioral limits, and finally address the administrative issue of consent.
When managing acute family conflict and dysfunctional dynamics in a clinical setting, the nurse must apply Maslow's hierarchy and crisis intervention principles. The priority is the direct client's safety and psychological well-being, achieved by ensuring a staff member remains with the adolescent. Next, the nurse must protect the unit milieu by relocating the disruption to a private area. Once in a private setting, de-escalation begins with therapeutic validation of the parents' feelings, followed by setting firm behavioral limits. Only after the emotional crisis is managed should the nurse address the specific logistical cause of the argument, which in this case is determining legal consent authority.

Step-by-Step Solution

1
Ensure the client has immediate support by assigning a colleague to the bedside.
The client is emotionally supported and protected from further immediate distress.
The client's immediate psychological and physical safety is always the highest nursing priority.
2
Direct the parents to a private room away from the clinical area.
The argument is removed from the unit milieu.
Separating the conflicting parties from the stressor (the treatment area) is the first physical step in crisis de-escalation.
3
Validate the parents' underlying concerns using therapeutic communication.
The parents feel heard, which lowers their emotional reactivity and defensiveness.
De-escalation requires establishing a baseline of empathy before rules can be enforced or problems can be solved.
4
Set clear limits on acceptable behavior.
Therapeutic boundaries are established for the remainder of the hospital stay.
Clear boundaries maintain a safe environment for care delivery and prevent a recurrence of the crisis.
5
Check the medical record for legal guardianship and consent authority.
The clinical dispute is resolved using objective legal documentation.
Administrative conflict resolution cannot succeed while the parties are in an acute state of emotional dysregulation.

Question 45Question →

A nurse is removing a central venous catheter from a client's subclavian vein. Immediately after the catheter is withdrawn, the client suddenly gasps for air, reports sharp chest pain, and becomes severely dyspneic and pale. Suspecting an air embolism, arrange the following nursing actions in the priority order they should be performed to reduce the risk of a fatal cardiopulmonary complication.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct priority sequence is: first, apply a sterile occlusive dressing; second, position the client in the left lateral Trendelenburg position; third, administer 100% oxygen; fourth, activate the rapid response system; and finally, initiate continuous monitoring.
In the event of a suspected air embolism during central line removal, the nurse's immediate goal is risk reduction through sequential mechanical and physiological interventions. Applying an occlusive dressing stops further air entrainment. The left lateral Trendelenburg position then traps the air in the right ventricle, preventing a catastrophic pulmonary artery occlusion. High-flow oxygen is administered to treat tissue hypoxia and accelerate nitrogen resorption from the embolus. Only after these immediate, life-saving bedside steps are taken should the nurse activate the rapid response team, followed by continuous hemodynamic monitoring to evaluate the client's status.

Step-by-Step Solution

1
Apply a sterile occlusive dressing firmly over the insertion site.
Further air entry into the venous system is immediately halted.
Every second the site remains open allows more air to be entrained, rapidly worsening the embolus. Stopping the source is the immediate mechanical priority.
2
Place the client in the left lateral Trendelenburg position.
The air embolus is trapped in the apex of the right ventricle.
This specific position utilizes gravity to prevent the air from migrating into the pulmonary artery, which would cause an infarction and cardiopulmonary collapse.
3
Administer 100% oxygen via a non-rebreather mask.
Hypoxia is addressed and the size of the nitrogen-based air bubble begins to shrink.
High-flow oxygen creates a diffusion gradient that accelerates the resorption of nitrogen gas from the embolus into the bloodstream while treating tissue ischemia.
4
Activate the rapid response system and notify the healthcare provider.
Advanced medical assistance and diagnostic support are summoned to the bedside.
After stabilizing the client with immediate nursing interventions, advanced medical care is required for definitive treatment.
5
Initiate continuous monitoring of vital signs and oxygen saturation.
The client's physiological status is closely observed for further decompensation.
Ongoing assessment evaluates the effectiveness of the initial interventions and guides further resuscitation efforts by the medical team.

Question 46Question →

A client on a medical-surgical unit is receiving an infusion of packed red blood cells (PRBCs) for symptomatic anemia. Ten minutes after the transfusion begins, the client reports sudden severe lower back pain, dyspnea, and chills. The nurse notes visible flushing and shivering. Place the following nursing interventions in the correct order of priority. (Arrange from first action to last action.)

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence of actions for a suspected blood transfusion reaction is: 1) Stop the blood transfusion immediately. 2) Change the IV tubing and infuse 0.9% sodium chloride. 3) Assess the client's vital signs and clinical status. 4) Notify the primary healthcare provider and the blood bank. 5) Return the blood bag, attached tubing, and labels to the blood bank.
In any adverse transfusion reaction, the absolute first priority is to remove the source of harm (stop the transfusion). The second priority is to maintain an open venous access line for emergency medications using entirely new tubing and normal saline. Assessing the client follows securing the line, providing the necessary clinical data to report to the healthcare provider. The provider is then notified, and finally, administrative and diagnostic protocols such as returning the blood to the lab are completed.

Step-by-Step Solution

1
Stop the transfusion immediately.
Halts the entry of incompatible blood into the client's systemic circulation.
Continuing the transfusion exacerbates the acute hemolytic reaction, increasing the risk of cardiovascular collapse and acute kidney injury.
2
Change IV tubing and run normal saline.
Maintains intravenous access without flushing the remaining blood product into the client.
If the existing tubing is used to flush normal saline, the client will receive the blood left in the line. A new line ensures safe access for emergency drugs.
3
Assess the client's vital signs and respiratory status.
Gathers objective data regarding the client's hemodynamic stability.
The nurse must have current vital signs (e.g., blood pressure, oxygen saturation) and clinical findings to accurately report the client's condition to the provider.
4
Notify the healthcare provider and blood bank.
Triggers medical intervention and laboratory investigation.
The provider will prescribe necessary emergency interventions, and the blood bank must initiate their transfusion reaction protocols.
5
Return the blood products and tubing to the blood bank.
Preserves the physical evidence of the reaction.
The blood bank must test the bag, tubing, and labels to determine if there was a crossmatching error or bacterial contamination.

Key Concept

Management of acute hemolytic transfusion reactions requires immediate cessation of the blood product, maintaining a patent IV with new tubing, and comprehensive client assessment before provider notification.
Question 47Question →

A nurse is caring for an alert and oriented client with diabetes mellitus who reports feeling shaky and sweaty. The client's capillary blood glucose level is 55 mg/dL. Arrange the following nursing interventions in the correct order of priority.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence follows the 'Rule of 15' for managing hypoglycemia: administer 15 grams of simple carbohydrates, wait 15 minutes, reassess blood glucose, and finally provide a sustaining snack.
The 'Rule of 15' is the standard protocol for managing mild to moderate hypoglycemia in a conscious client. It begins with the immediate administration of 15 grams of a fast-acting carbohydrate to rapidly raise blood glucose. The nurse then waits 15 minutes to allow for absorption before reassessing the blood glucose level. If the level remains below 70 mg/dL, the process is repeated. Once the level normalizes (above 70 mg/dL), a complex carbohydrate and protein snack is provided to maintain blood glucose stability.

Step-by-Step Solution

1
Administer a fast-acting carbohydrate.
The client consumes 15 grams of simple carbohydrates.
Immediate treatment is necessary to raise the blood glucose level rapidly and prevent neurological deterioration in a conscious, hypoglycemic client.
2
Wait for 15 minutes.
Time is provided for digestion and absorption.
It takes roughly 15 minutes for the simple carbohydrates to be absorbed into the bloodstream and effectively raise the blood glucose.
3
Reassess blood glucose.
The blood glucose is checked to evaluate the client's response.
Reassessment determines if the initial intervention was successful (glucose is > 70 mg/dL) or if the 15-gram carbohydrate dose needs to be repeated.
4
Provide a sustaining snack.
The client eats a snack with complex carbohydrates and protein.
This prevents secondary hypoglycemia by providing a slower, sustained release of glucose into the bloodstream.

Question 48Question →

A nurse is educating a client who has a right fractured tibia and is prescribed non-weight-bearing status. The client is learning to ascend a flight of stairs using axillary crutches. In what order should the nurse instruct the client to perform the following movements?

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The client should first assume a tripod position, transfer weight to the crutches, advance the unaffected leg up the step, shift weight to the unaffected leg, and finally bring the affected leg and crutches up to the step.
When ascending stairs with crutches, the fundamental principle is 'up with the good, down with the bad.' The client must begin with a stable tripod stance, support their weight on the crutches, and step up with the unaffected (strong) leg first. Once the strong leg is on the step, the client shifts their weight onto it and uses its strength to lift the affected leg and the crutches simultaneously up to the step.

Step-by-Step Solution

1
Assume the tripod position facing the bottom of the stairs.
The client establishes a stable base.
A secure starting stance is necessary for balance and safety before moving.
2
Transfer body weight entirely onto the crutches.
The client's legs are freed from bearing weight.
This allows the client to lift the strong leg without losing balance.
3
Move the unaffected left leg up onto the stair tread.
The strong leg is positioned on the higher level.
When ascending stairs, the unaffected ('good') leg always goes first to provide the power to lift the body weight.
4
Shift body weight from the crutches onto the unaffected left leg.
Weight is transferred to the elevated strong leg.
The strong leg must bear the body weight to pull the rest of the body upward.
5
Advance the right leg and both crutches together up to the step.
The client completes the ascent of one step.
The crutches and the affected leg follow the strong leg to the new level, completing the movement sequence.

A registered nurse (RN) on a medical-surgical unit is preparing to delegate the insertion of a straight urinary catheter for a client with acute urinary retention to a licensed practical/vocational nurse (LPN/VN). Arrange the following steps of the delegation process in the correct chronological order according to national delegation guidelines. (Place the first step at the top and the final step at the bottom.)

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence of delegation is to first assess the client, then verify the LPN/VN's competency, provide specific instructions, monitor the execution of the task, and finally evaluate the outcome and provide feedback.
Safe delegation requires a systematic, chronological approach. The RN must first assess the client's condition to determine if the task is safe to delegate (Assess). Next, the RN assesses the delegatee's competence (Plan). Then, clear communication is provided (Communicate), followed by active supervision during the task (Supervise). Finally, the RN evaluates the client's response and provides feedback (Evaluate).

Step-by-Step Solution

1
Assess the client's stability and the complexity of the task.
Determines if the specific situation is safe for delegation.
The RN maintains accountability for client safety; unstable clients or highly complex, unpredictable tasks should not be delegated.
2
Verify the delegatee's competence and scope of practice.
Ensures the selected staff member is legally and clinically capable.
Delegating to an unqualified individual violates the 'Right Person' principle and endangers the client.
3
Communicate clear instructions and expectations.
The delegatee understands exactly what to do, how to do it, and what to report.
Clear, two-way communication prevents errors and establishes boundaries for the delegated task.
4
Monitor and supervise the performance of the task.
Ensures the procedure is carried out safely according to facility policy.
The RN remains accountable for the task and must be available to intervene if complications arise.
5
Evaluate the results and provide feedback.
Closes the delegation loop and ensures the client's needs were met.
Evaluation is necessary to determine if the desired outcome was achieved and to promote the professional growth of the delegatee.

An older adult client with advanced Alzheimer's disease is admitted for severe dehydration. The client continuously attempts to pull out their peripheral intravenous (IV) line despite the implementation of multiple non-restrictive safety measures. The healthcare provider has prescribed bilateral soft wrist restraints. Arrange the following nursing actions in the correct sequence of execution from first to last.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence is to first review the prescription, then explain the procedure to the client, apply the cuffs checking for a two-finger clearance, secure the ties to the movable bed frame, and finally assess and document distal circulation.
The application of physical restraints requires a strict, systematic approach to prioritize legal requirements, client rights, and safety. First, a valid healthcare provider's prescription must be verified. Next, the nurse must explain the procedure to the client to reduce anxiety. The restraints are then applied to the wrists, ensuring a two-finger gap remains to maintain adequate circulation. After proper placement, the ties are secured to the movable part of the bed frame using a quick-release knot, which prevents injury when the bed is adjusted. Finally, the nurse must immediately assess and document the client's distal neurovascular status.

Step-by-Step Solution

1
Verify the medical order.
The nurse confirms the prescription is valid and complete.
A legal prescription is mandatory before any physical restraint application.
2
Explain the procedure.
The client is informed about the restraints.
Communication respects client autonomy and helps reduce confusion or fear, even in clients with cognitive impairment.
3
Apply the restraint cuffs.
The cuffs are placed on the wrists with appropriate slack.
Ensuring a two-finger gap prevents neurovascular injury and skin breakdown.
4
Secure the ties.
The restraint ties are attached to the movable bed frame.
This prevents patient injury during bed position changes and allows for rapid release during an emergency.
5
Assess and document.
Neurovascular status is evaluated and recorded.
Continuous monitoring prevents complications like ischemia and ensures facility protocol compliance.

Key Concept

Safe application and monitoring of physical restraints requires a stepwise approach to ensure legal compliance, client dignity, and physical safety.

Question 51Question →

A client requires a large-volume cleansing enema to relieve severe constipation. In what chronological sequence should the nurse perform the steps of this procedure?

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence is: position the client on their left side, apply lubricant to the tube, insert the tube 3 to 4 inches, elevate the bag 12 to 18 inches, and release the clamp to instill the fluid.
The correct sequence ensures both client safety and the physiological effectiveness of the enema. Positioning the client appropriately must occur first to align the anatomy. Lubricating the tube is necessary immediately prior to insertion to prevent mucosal tears. Once inserted properly towards the umbilicus, the bag is elevated to the recommended height to control fluid pressure. Finally, the flow is initiated while actively monitoring the client's physical tolerance.

Step-by-Step Solution

1
Client Positioning
The client is placed in the left lateral Sims' position.
This anatomical position allows gravity to assist the downward flow of fluid into the descending colon.
2
Equipment Preparation
The distal tip of the rectal tube is covered with water-soluble lubricant.
Lubrication prevents tissue injury and minimizes discomfort during insertion.
3
Tube Insertion
The tube is inserted 3 to 4 inches toward the umbilicus.
This follows the natural anatomical pathway of the lower bowel without causing perforation.
4
Pressure Adjustment
The enema bag is positioned 12 to 18 inches above the anus.
This specific height provides a safe, steady hydrostatic pressure without causing excessive bowel distension.
5
Fluid Instillation
The fluid is administered slowly into the rectum.
Rapid instillation can cause severe cramping and premature expulsion of the enema, defeating the purpose of the procedure.

A nurse is preparing to remove a client's non-tunneled percutaneous central venous catheter (CVC). To minimize the risk of an air embolism, in what order should the nurse perform the following actions? Arrange the steps in the correct sequence from first to last.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence for removing a central venous catheter to prevent air embolism is to first position the client supine, then instruct them to perform the Valsalva maneuver, remove the catheter smoothly, apply immediate direct pressure, and finally secure an occlusive dressing.
Preventing an air embolism during CVC removal requires manipulating pressure gradients. Supine positioning and the Valsalva maneuver increase central venous pressure above atmospheric pressure. Swift removal limits exposure time, followed immediately by pressure and an occlusive dressing to seal the tract.

Step-by-Step Solution

1
Place the client in a supine or Trendelenburg position.
Intrathoracic venous pressure is increased.
Lowering the head of the bed utilizes gravity to increase venous pressure above atmospheric pressure, reducing the risk of air being sucked into the central circulation.
2
Instruct the client to take a deep breath and bear down.
The client performs the Valsalva maneuver.
This maneuver further raises intrathoracic pressure precisely at the moment the vein will be exposed, creating a positive pressure gradient that pushes blood out rather than pulling air in.
3
Remove the catheter smoothly and continuously.
The catheter is extracted without tissue trauma.
A swift, continuous motion limits the duration the venous pathway is open to the atmosphere.
4
Apply direct manual pressure to the site with sterile gauze.
Hemostasis begins and the entry tract is physically blocked.
Firm pressure for 5 to 10 minutes stops bleeding and prevents air aspiration while a stable clot forms.
5
Apply an airtight occlusive dressing over the site.
The insertion site is completely sealed.
An occlusive dressing prevents any delayed air entry into the tract over the next 24 to 72 hours.

A critically ill client is admitted to the intensive care unit with a diagnosis of severe diabetic ketoacidosis. Initial laboratory results reveal a serum glucose of 815815 mg/dL (45.245.2 mmol/L), an arterial pH of 7.087.08, and a serum potassium of 3.03.0 mEq/L (3.03.0 mmol/L). The client exhibits profound lethargy, deep and rapid respirations, and poor skin turgor. Arrange the following therapeutic interventions in the correct physiological priority sequence to safely manage this client's acute decompensation.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct priority sequence is: 1) Initiate 0.9%0.9\% sodium chloride, 2) Administer potassium chloride, 3) Commence regular insulin, 4) Evaluate blood glucose until it reaches 250250 mg/dL, 5) Incorporate 5%5\% dextrose into fluids.
The management of diabetic ketoacidosis requires a precise sequence to adapt to the physiological crisis. First, severe osmotic diuresis causes profound hypovolemia, making rapid fluid resuscitation with 0.9%0.9\% sodium chloride the absolute priority to restore perfusion. Second, the client's potassium is critically low (3.03.0 mEq/L). Because insulin drives potassium into the cells, administering insulin before replacing potassium would trigger life-threatening hypokalemia and cardiac dysrhythmias. Therefore, potassium chloride must be administered next. Third, a continuous regular insulin infusion is started to halt ketogenesis and correct the metabolic acidosis. Fourth, serial blood glucose levels are monitored closely. Finally, when the blood glucose decreases to 250250 mg/dL (13.913.9 mmol/L), 5%5\% dextrose is added to the intravenous fluids. This prevents hypoglycemia and cerebral edema while allowing the insulin infusion to continue until the anion gap closes and acidosis resolves.

Step-by-Step Solution

1
Initiate a rapid intravenous infusion of 0.9%0.9\% sodium chloride.
Restores intravascular volume and organ perfusion.
Severe osmotic diuresis leads to profound hypovolemia; fluid resuscitation is the absolute first priority to stabilize blood pressure, reverse shock, and improve renal function.
2
Administer the prescribed intravenous potassium chloride.
Corrects the severe hypokalemia.
The client's potassium is critically low at 3.03.0 mEq/L. Because insulin shifts potassium intracellularly, administering insulin first would worsen hypokalemia and potentially trigger lethal cardiac dysrhythmias.
3
Commence a continuous intravenous infusion of regular insulin.
Halts ketogenesis and lowers blood glucose.
Once intravascular volume is expanding and potassium is safely being replaced, insulin is required to drive glucose into cells, thereby correcting the metabolic acidosis.
4
Evaluate serial blood glucose levels until they reach 250250 mg/dL (13.913.9 mmol/L).
Identifies the threshold for modifying fluid therapy.
As insulin works, glucose drops rapidly. Monitoring identifies the critical inflection point to prevent hypoglycemia while allowing insulin to continue clearing ketones.
5
Incorporate 5%5\% dextrose into the intravenous maintenance fluids.
Prevents rapid shifts in serum osmolality and hypoglycemia.
Adding dextrose provides a continuous substrate for the insulin infusion (which must continue until the anion gap closes) and prevents cerebral edema from a rapid drop in osmolality.

Key Concept

In severe diabetic ketoacidosis, priority management follows a strict physiological sequence: restore intravascular volume first, correct severe hypokalemia prior to administering insulin (to prevent lethal dysrhythmias), initiate insulin to reverse acidosis, and add dextrose when glucose reaches 250250 mg/dL to prevent hypoglycemia.

A triage nurse in the emergency department receives a client with acute kidney injury secondary to severe rhabdomyolysis. The client reports profound muscle weakness. A STAT 12-lead electrocardiogram reveals absent P waves, a heart rate of 42 bpm42\text{ bpm}, and markedly widened QRS complexes. Arrange the following nursing actions in the most appropriate priority order from first to last.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct order is: Place the client on a continuous cardiac monitor, followed by administering IV calcium gluconate, then IV regular insulin with dextrose, then oral sodium polystyrene sulfonate, and finally drawing blood for a repeat potassium level.
The correct sequence aligns with the principles of acute physiological resuscitation: immediate safety monitoring (ECG), rapid stabilization of vital organ function (Calcium for the myocardium), acute temporizing treatment (Insulin/Dextrose for shifting), delayed definitive treatment (Sodium polystyrene sulfonate for elimination), and post-intervention evaluation (Repeat labs).

Step-by-Step Solution

1
Ensure continuous visualization of the cardiac rhythm.
The client is placed on a continuous cardiac monitor with defibrillator pads readily available.
The client has a symptomatic, life-threatening arrhythmia due to severe hyperkalemia. Continuous monitoring is required to immediately detect deterioration into a lethal arrhythmia.
2
Initiate myocardial membrane stabilization.
Intravenous calcium gluconate is administered.
Calcium gluconate is the absolute first-line pharmacological agent for hyperkalemia with ECG changes. It does not lower potassium but raises the myocardial threshold potential, protecting the heart from ventricular fibrillation within minutes.
3
Initiate intracellular potassium shifting.
Intravenous regular insulin and 50% dextrose are administered.
Once the myocardium is stabilized, the next priority is to rapidly lower the serum potassium level. Insulin drives potassium into cells (working in 15-30 minutes), and dextrose prevents profound hypoglycemia.
4
Initiate definitive potassium elimination.
Sodium polystyrene sulfonate is administered.
After temporizing measures are completed, a medication that permanently removes potassium from the gastrointestinal tract is given. Because this resin takes hours to days to significantly lower serum levels, it cannot be given before stabilization.
5
Evaluate the response to therapeutic interventions.
Blood is drawn for a repeat serum potassium level and basic metabolic panel.
Evaluation is the final step of the acute nursing process to determine if extracellular potassium has shifted adequately or if emergent hemodialysis is now required.

Key Concept

The physiological sequencing of hyperkalemia management prioritizes myocardial stabilization, followed by intracellular shifting, and finally bodily elimination.

A client is 6 hours post-coronary artery bypass graft (CABG) surgery and is receiving mechanical ventilation. The intensive care nurse notes that the mediastinal chest tube drainage, which had been steadily draining 100 mL/hr100\text{ mL/hr}, has abruptly ceased over the past 45 minutes. The client's blood pressure drops from 115/75 mmHg115/75\text{ mmHg} to 82/64 mmHg82/64\text{ mmHg}, heart rate increases from 85 bpm85\text{ bpm} to 128 bpm128\text{ bpm}, and central venous pressure (CVP) rapidly rises from 8 mmHg8\text{ mmHg} to 19 mmHg19\text{ mmHg}. Jugular venous distension is visible. The nurse suspects acute cardiac tamponade. Place the following collaborative and nursing actions in the correct priority sequence.

Answer

The correct sequence is: 1) Auscultate the precordium for muffled heart sounds, 2) Notify the cardiothoracic surgeon, 3) Administer a rapid IV fluid bolus, 4) Facilitate a stat bedside echocardiogram, and 5) Assemble the pericardiocentesis tray.
The correct sequence strictly follows the nursing process and emergency prioritization (Assessment -> Escalation -> Temporizing Intervention -> Diagnostics -> Definitive Procedure). In obstructive shock from cardiac tamponade, immediate recognition (assessing Beck's triad) must precede calling the provider. Once help is activated, a fluid bolus is the priority medical intervention to increase preload and overcome pericardial compression. Diagnostics (echocardiogram) confirm the effusion, followed by preparation for the definitive procedure (pericardiocentesis or chest reopening).

Step-by-Step Solution

1
Assess for muffled heart sounds.
Completes the rapid focused assessment for Beck's triad.
Before calling the provider, the nurse must quickly gather all necessary clinical data to provide a comprehensive and accurate SBAR report.
2
Notify the surgeon and rapid response team.
Escalates the critical situation to providers.
Cardiac tamponade cannot be resolved with nursing interventions alone; it requires immediate procedural intervention to prevent cardiac arrest.
3
Administer the prescribed IV fluid bolus.
Increases right-sided cardiac preload.
A fluid bolus temporarily increases venous return to force blood into the compressed right heart, maintaining cardiac output until the effusion can be drained.
4
Facilitate a stat bedside echocardiogram.
Provides diagnostic confirmation.
The medical team uses ultrasound to visualize the pericardial fluid and right ventricular collapse prior to performing an invasive needle insertion.
5
Assemble the pericardiocentesis tray.
Prepares the environment for definitive treatment.
Once confirmed, the fluid must be physically drained via pericardiocentesis or emergency sternotomy to permanently relieve the obstructive shock.

A 3434-year-old client with a known history of Graves' disease is admitted to the progressive care unit exhibiting extreme restlessness, profound diaphoresis, and delirium. Current vital signs reveal a heart rate of 188 beats/min188\text{ beats/min}, blood pressure of 182/104 mmHg182/104\text{ mmHg}, and a core temperature of 40.6∘C40.6^\circ\text{C} (105.1∘F105.1^\circ\text{F}). The client is diagnosed with a thyrotoxic crisis (thyroid storm). The healthcare provider prescribes several emergent interventions. Arrange the following actions in the correct physiological priority order.

Answer

The correct sequence is: 1) Apply supplemental oxygen, 2) Administer intravenous propranolol, 3) Administer enteral propylthiouracil (PTU), 4) Administer Lugol's iodine solution, 5) Administer intravenous hydrocortisone.
In a thyroid storm, the physiological hierarchy of needs dictates the sequence of care. The most immediate threat is cellular hypoxia and cardiovascular collapse from sympathetic overdrive. Therefore, oxygenation and beta-blockade (propranolol) are initiated first. Once hemodynamics are stabilized, the source of the crisis must be addressed pharmacologically. It is a critical physiological principle that new hormone synthesis must be blocked by propylthiouracil (PTU) before administering iodine. If iodine is given first, the hyperactive thyroid gland will rapidly use it to synthesize more hormone. Once synthesis is blocked, Lugol's iodine is given to halt the release of already-stored hormone. Finally, corticosteroids (hydrocortisone) are administered to replace depleted adrenal reserves and assist in decreasing peripheral hormone conversion.

Step-by-Step Solution

1
Prioritize tissue perfusion and oxygenation by applying supplemental oxygen.
Meets the escalated metabolic and cellular oxygen demands.
Airway and breathing are the foundational steps in any acute decompensation, especially when metabolic consumption is massively elevated.
2
Administer the prescribed beta-adrenergic antagonist (propranolol).
Rapidly decreases the heart rate of 188 beats/min188\text{ beats/min} and lowers blood pressure.
Sympathetic overdrive poses the most immediate threat to life via cardiovascular collapse.
3
Administer the thionamide derivative (propylthiouracil).
Halts the ongoing synthesis of new thyroid hormone in the thyroid gland.
Synthesis must be stopped before iodine is introduced to the system to prevent paradoxical worsening of the crisis.
4
Administer the iodine solution (Lugol's solution) at least one hour after the thionamide.
Inhibits the release of preformed, stored thyroid hormone into the bloodstream.
This exploits the Wolff-Chaikoff effect safely, provided synthesis has already been blocked.
5
Administer glucocorticoids (hydrocortisone).
Provides adrenal support and further blunts the peripheral conversion of T4T_4 to T3T_3.
The profound hypermetabolic state quickly depletes endogenous cortisol, requiring replacement after acute stabilization.

Key Concept

The management of thyrotoxic crisis requires a strict pathophysiological sequence: stabilizing oxygenation, controlling adrenergic overdrive, blocking hormone synthesis with thionamides, blocking hormone release with iodine, and providing adrenal support. Iodine must never precede thionamides.

A nurse is caring for a client with a complete T4T4 spinal cord injury. The client suddenly reports a severe, pounding headache and blurred vision. The nurse observes profuse diaphoresis and flushing above the level of the spinal lesion, accompanied by marked pallor and piloerection below the lesion. The client's blood pressure is 220/115220/115 mmHg and heart rate is 4848 bpm. Place the following nursing interventions in the correct sequence of priority to manage this acute complication.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence is: 1) Elevate the head of the bed, 2) Assess and relieve urinary obstruction, 3) Evaluate for bowel impaction, 4) Administer antihypertensive medication, and 5) Document the event.
The priority in managing autonomic dysreflexia is to rapidly lower the dangerously high blood pressure to prevent a hemorrhagic stroke. Elevating the head of the bed utilizes gravity to induce orthostatic pooling of blood in the lower extremities, providing an instant reduction in blood pressure. Once the client is safely positioned, the nurse must systematically identify and eliminate the noxious stimulus driving the sympathetic surge. Because bladder distension is the most common cause, the urinary system is assessed first. If the bladder is empty, bowel impaction (the second most common cause) is assessed next. If these physical measures fail to resolve the crisis, rapid-acting pharmacological antihypertensives are administered. Finally, once the client is stable, the nurse documents the entire event.

Step-by-Step Solution

1
Recognize the clinical presentation of autonomic dysreflexia.
The symptoms (severe hypertension, bradycardia, pounding headache, diaphoresis above the lesion) indicate a medical emergency requiring immediate reduction of blood pressure.
Identifying the syndrome dictates the specific crisis management protocol.
2
Prioritize immediate physical positioning over diagnostic assessment.
Elevating the head of the bed to 9090 degrees is selected as the absolute first action.
Positioning utilizes orthostatic principles to instantly lower blood pressure, mitigating the immediate risk of a catastrophic hemorrhagic stroke.
3
Systematically assess for and eliminate noxious stimuli, starting with the most common.
Checking the bladder is prioritized next, followed by checking the bowel.
Removing the underlying trigger (usually a distended bladder or bowel impaction) stops the unchecked sympathetic nervous system response.
4
Determine the role of pharmacological interventions.
Antihypertensive medications are placed after mechanical interventions.
Medications are used if the blood pressure remains dangerously elevated despite the removal of mechanical triggers.

Key Concept

Autonomic dysreflexia is a life-threatening sympathetic response in clients with spinal cord injuries at or above T6T6. Management requires immediate positioning to lower blood pressure via orthostasis, followed by rapid identification and removal of the noxious stimulus (usually bladder or bowel).

Show answer & explanation

Answer

The correct sequence is: 1) Assess the mediastinal chest tubes for kinks, 2) Activate the rapid response team and notify the surgeon, 3) Administer a rapid intravenous crystalloid bolus, 4) Prepare for an immediate bedside echocardiogram, and 5) Gather the pericardiocentesis tray and prepare for sternotomy.
Cardiac tamponade post-CABG is a form of obstructive shock. The priority sequence reflects the nursing process and emergency prioritization: rapidly identify and reverse simple mechanical causes (kinked tubes), mobilize the emergency surgical team, support hemodynamics with increased preload (crystalloid fluids), assist with diagnostics (echocardiogram), and prepare for definitive surgical decompression.

Step-by-Step Solution

1
Assess the mediastinal chest tubes for kinks or dependent loops.
Ensures there is no mechanical obstruction preventing pericardial drainage.
Resolving an obstruction is the quickest, least invasive way to reverse the accumulating fluid causing the tamponade. Independent nursing assessment of the equipment takes priority.
2
Activate the rapid response team and notify the cardiothoracic surgeon.
Mobilizes necessary medical personnel for an escalating emergency.
Cardiac tamponade is a lethal surgical complication requiring advanced interventions beyond the independent nursing scope of practice.
3
Administer a rapid intravenous crystalloid bolus as prescribed.
Increases right ventricular preload and systemic venous pressure.
Elevating filling pressures is hemodynamically essential to temporarily overcome the restrictive pericardial pressure and maintain cardiac output until the fluid can be drained.
4
Prepare the client for an immediate bedside echocardiogram.
Facilitates diagnostic confirmation of pericardial effusion.
The provider must visually confirm the presence and severity of the tamponade before proceeding with high-risk invasive procedures.
5
Gather the pericardiocentesis tray and prepare for a potential emergent sternotomy.
Readies the clinical environment for definitive treatment.
Evacuation of the pericardial fluid is the ultimate curative step, requiring sterile equipment and immediate surgical readiness.

A registered nurse realizes that an incorrect intravenous (IV) high-alert medication has just been initiated for an adult client. Arrange the following nursing actions in the priority sequence the nurse should perform them to mitigate harm and manage the error.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct priority sequence is to first stop the infusion, then assess the client, notify the healthcare provider, implement prescribed interventions, and finally complete an incident report.
When a medication error occurs, the nursing process and safety principles dictate a specific priority framework. First, stop the source of harm immediately (stop the IV). Second, assess the client for adverse effects to gather data. Third, notify the healthcare provider using the gathered assessment data. Fourth, carry out any new emergency prescriptions or interventions to stabilize the client. Finally, complete administrative reporting only after the client's physiological needs are met.

Step-by-Step Solution

1
Stop the intravenous infusion of the incorrect medication immediately.
Further administration of the harmful agent is halted.
The absolute first priority in any active adverse event is to remove or stop the source of harm.
2
Assess the client's vital signs and monitor for adverse physiological reactions.
Baseline clinical status and any immediate adverse reactions are identified.
Assessment data is necessary to determine the extent of harm and to accurately inform the healthcare provider.
3
Notify the healthcare provider of the error and the client's current status.
The provider is informed of the error and the client's condition.
The provider must evaluate the assessment data to determine if antidotes or supportive therapies are required.
4
Administer prescribed antidotes or supportive interventions as ordered.
The client receives necessary treatment for any adverse effects.
Immediate physiological stabilization and treatment are prioritized over administrative duties.
5
Complete a facility incident or variance report detailing the event.
The event is formally documented for facility safety review.
Incident reporting is essential for identifying systemic errors and preventing future occurrences, but it must never delay direct client care.

Answer

The correct sequence of actions for a bomb threat call is to first keep the caller on the line, then signal a coworker to contact security, followed by asking specific questions about the device, noting caller characteristics, and finally completing the formal documentation checklist after the call ends.
In the event of a telephonic bomb threat, the overarching goal of the emergency response plan is to maximize information gathering while simultaneously activating security protocols. Keeping the caller on the line is the absolute first priority. Signaling a coworker allows for immediate security dispatch without interrupting the flow of the call. Asking direct questions about the bomb and noting background noises are active listening tasks performed during the conversation. Finally, formal documentation must occur immediately after disconnection to preserve accurate memories.

Step-by-Step Solution

1
Maintain the phone connection.
The caller remains on the line.
Gathering intelligence is the primary goal; hanging up ends the opportunity to obtain life-saving information.
2
Discreetly alert a coworker.
Security and law enforcement are notified.
Emergency response must be initiated concurrently without interrupting the caller or causing them to hang up.
3
Interrogate the caller for details.
Information about the device's location and timing is obtained.
Specific details are required to determine the necessary scope of hospital evacuation and immediate danger zones.
4
Analyze voice and background sounds.
Investigative clues are identified.
Characteristics like accents, machinery, or traffic noise can help authorities locate the caller and assess the threat's validity.
5
Document the incident on a standardized checklist.
A permanent record is created for investigators.
Writing down the details immediately ensures accuracy for the police investigation before memory fades in a high-stress situation.
