While conducting hourly rounds, a nurse observes that the intravenous administration set has completely disconnected from a client's central venous catheter hub. The client abruptly exhibits severe dyspnea, a dry cough, and grasps their chest in distress. In which sequence must the nurse execute the following interventions? (Arrange the actions in order of clinical priority, from first to last.)

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The nurse must first clamp the catheter, then place the client in a left lateral Trendelenburg position, administer high-flow oxygen, activate the rapid response team, and finally obtain vital signs.
An air embolism is a life-threatening complication of central venous access devices that occurs when the system is open to atmospheric pressure. The sequence of actions follows the principle of immediate risk reduction and airway/breathing stabilization. The absolute first priority is to stop the source of the air by clamping the catheter. Next, positioning the client on their left side with the head down (Trendelenburg) uses gravity to trap the air in the apex of the right ventricle, preventing a fatal pulmonary artery occlusion. After securing the source and mitigating migration, 100% oxygen is applied to treat hypoxia and shrink the nitrogen-rich air bubble. Finally, the nurse calls for advanced help and assesses vital signs to guide the team's ongoing resuscitation efforts.

Step-by-Step Solution

1
Clamp the central venous catheter.
Stops the entrainment of air.
The absolute first priority is removing the immediate hazard by closing the pathway that allows air to enter the bloodstream.
2
Place the client in the left lateral Trendelenburg position.
Traps the air embolus in the right ventricle.
This maneuver prevents the air from advancing into the pulmonary artery, averting a right ventricular outflow tract obstruction.
3
Administer 100% oxygen via a non-rebreather face mask.
Relieves hypoxia and reduces the size of the embolus.
Providing 100% oxygen promotes the diffusion of nitrogen out of the air bubble, effectively shrinking the embolus while treating ischemia.
4
Activate the rapid response team.
Mobilizes advanced medical support.
Additional personnel and advanced interventions are necessary, but calling for help must not delay the initial life-saving physical maneuvers.
5
Measure the client's vital signs and oxygen saturation.
Establishes a baseline for the responding team.
Assessment data is required to evaluate the severity of the physiological decompensation, but it is the lowest priority compared to active resuscitation efforts.

A registered nurse in a university student health center is initiating a skin cancer primary prevention intervention for a newly enrolled young adult. In what order should the nurse implement the following actions? Arrange them from first to last.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence follows the nursing process (ADPIE): Assess current habits, identify learning needs (Diagnosis/Analysis), establish goals (Planning), educate the client (Implementation), and evaluate understanding (Evaluation).
When implementing any health promotion strategy, client teaching, or primary prevention plan, the registered nurse must follow the systematic approach of the nursing process. This ensures care is individualized, safe, and effective. The sequence must always be Assessment (gathering data on habits), Diagnosis/Analysis (identifying risks and learning needs), Planning (setting collaborative goals), Implementation (providing the actual education), and Evaluation (verifying understanding via teach-back).

Step-by-Step Solution

1
Place the assessment phase first.
Selected 'Assess the student's current outdoor activities...'
The nursing process always begins with data collection and assessing the client's baseline knowledge and current practices.
2
Place the diagnosis/analysis phase second.
Selected 'Identify the client's specific learning needs...'
Once data is collected, the nurse must analyze it to pinpoint the exact risks and educational deficits.
3
Place the planning phase third.
Selected 'Collaborate with the student to establish realistic goals...'
Before teaching begins, the nurse and client must establish clear, mutually agreeable goals.
4
Place the implementation phase fourth.
Selected 'Educate the student on the proper application...'
The actual teaching and intervention execution happens according to the plan.
5
Place the evaluation phase last.
Selected 'Evaluate the student's comprehension...'
The final step is always to verify that the education was effective using methods like teach-back.

Question 663Question →

A nurse is caring for a client who is receiving intravenous fluids through a central venous catheter. The client suddenly gasps, reports severe chest pain, and becomes extremely short of breath. The nurse notes a heart rate of 124 beats/min, a blood pressure of 82/50 mm Hg, and auscultates a loud, churning "mill-wheel" murmur over the precordium. Suspecting a venous air embolism, arrange the following nursing actions in the correct priority order.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct order of actions is to first clamp the central venous catheter, then place the client in the left lateral Trendelenburg position, followed by administering 100% oxygen, activating the rapid response team, and finally documenting the event.
In a suspected venous air embolism, the nurse must prioritize immediate mechanical interventions to prevent cardiac arrest. The absolute first action is to stop the source by clamping the central venous catheter. Immediately after, the client is placed in the left lateral Trendelenburg position (Durant's maneuver) to trap the air in the apex of the right ventricle, preventing pulmonary artery obstruction. Once the air is trapped, administering 100% oxygen addresses hypoxia and creates a nitrogen gradient to shrink the bubble. With the immediate crisis stabilized, the nurse delegates calling for the rapid response team, and finally, documents the event after the situation is fully managed.

Step-by-Step Solution

1
Clamp the central venous catheter.
Halts the influx of air into the venous system.
Stopping the source is the absolute first priority in an iatrogenic air exposure to prevent worsening of the cardiovascular collapse.
2
Place the client in the left lateral Trendelenburg position.
Traps the air embolus in the right ventricle.
This specific positioning (Durant's maneuver) prevents the air bubble from entering the pulmonary artery, which would cause a fatal right ventricular outflow tract obstruction.
3
Administer 100% oxygen via a non-rebreather mask.
Treats hypoxia and shrinks the air bubble.
High-flow oxygen creates a diffusion gradient that washes out nitrogen from the bloodstream, causing the air embolus to decrease in size.
4
Instruct available personnel to activate the rapid response team.
Summons advanced medical support.
The client requires immediate medical evaluation and potential invasive interventions, such as aspiration of the air from the right atrium.
5
Document the critical event, interventions provided, and the client's response.
Creates an accurate legal and clinical medical record.
Thorough documentation must occur only after all emergency life-saving interventions are implemented and the client's immediate crisis is managed.

Question 664Question →

A nurse is caring for a client with type 2 diabetes mellitus whose morning blood glucose level is 185 mg/dL185 \text{ mg/dL}. The healthcare provider has prescribed 10 units10 \text{ units} of regular insulin and 20 units20 \text{ units} of NPH insulin to be administered subcutaneously. The nurse is preparing to mix both insulins in a single syringe. Arrange the following steps in the correct sequence for this procedure.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence is to first roll the NPH vial, inject air into the NPH vial, inject air into the regular insulin vial, withdraw the regular insulin, and finally withdraw the NPH insulin.
The standard sequence for mixing insulins ensures the fast-acting (clear) insulin is not contaminated by the intermediate-acting (cloudy) insulin. The correct mnemonic is often 'Clear before Cloudy'. The process is: mix the cloudy insulin by rolling, inject air into the cloudy vial, inject air into the clear vial, draw from the clear vial, and finally draw from the cloudy vial.

Step-by-Step Solution

1
Roll the NPH vial gently between the palms.
The cloudy suspension is mixed uniformly.
Vigorous shaking causes air bubbles which can lead to inaccurate dosing; rolling mixes the particles safely.
2
Inject 20 units20 \text{ units} of air into the NPH vial, then remove the needle.
The NPH vial is pressurized for later withdrawal.
Air must be injected to prevent a vacuum, but the medication is not drawn yet to prevent contamination.
3
Inject 10 units10 \text{ units} of air into the regular insulin vial.
The regular insulin vial is pressurized.
Prepares the vial for immediate withdrawal of the medication without removing the needle.
4
Invert the vial and withdraw 10 units10 \text{ units} of regular insulin.
The clear insulin is drawn into the syringe.
Drawing the clear (short-acting) insulin first prevents it from being contaminated by the longer-acting insulin.
5
Insert the needle into the NPH vial and withdraw 20 units20 \text{ units}.
The total dose of 30 units30 \text{ units} is drawn into the syringe.
Drawing the cloudy insulin last completes the mixture without risking contamination of the rapid or short-acting insulin vial.

A nurse is caring for a 62-year-old client who is 4 days post-operative following an open colon resection. While the nurse is assisting the client with coughing and deep breathing exercises, the client reports a sudden "popping" sensation in the abdomen. The nurse inspects the surgical site and observes a wound evisceration. Place the following nursing interventions in the correct order of priority to mitigate further physiological risk.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence is: 1) Remain with the client and call for assistance, 2) Position in low Fowler's with hips and knees flexed, 3) Cover the organs with sterile moistened dressings, 4) Obtain vital signs, 5) Prepare for emergency surgery (IV/NPO).
The priority sequence for wound evisceration follows the principle of immediate physical stabilization. Securing help without leaving the client is paramount. Next, placing the client in low Fowler's with flexed knees instantly reduces abdominal tension, stopping further organ protrusion. Only after this mechanical stabilization should the nurse apply sterile, moist dressings to prevent tissue necrosis. Once the viscera are protected, systemic assessment (vital signs) takes precedence, followed by definitive preparation for emergency surgery.

Step-by-Step Solution

1
Remain with the client and direct ancillary staff to immediately notify the rapid response team and surgical provider.
Emergency assistance is secured without abandoning an acutely unstable client.
An evisceration requires emergency surgical intervention and sterile supplies that the primary nurse cannot safely leave the room to retrieve.
2
Assist the client into a low Fowler's position with the hips and knees flexed.
Intra-abdominal pressure is immediately reduced.
This biomechanical intervention relaxes the abdominal rectus muscles, physically preventing further visceral protrusion from occurring while awaiting supplies.
3
Apply sterile, non-adherent dressings moistened with warm sterile normal saline over the protruding organs.
The eviscerated bowel is protected from necrosis and infection.
Exposed viscera will rapidly dry out and become ischemic if not covered with a warm, sterile, moist environment.
4
Obtain a comprehensive set of vital signs and assess peripheral perfusion for signs of hemorrhagic shock.
Systemic hemodynamic stability is evaluated.
Once the localized threat to the organs is managed, the nurse must assess for signs of systemic decompensation or concealed internal hemorrhage.
5
Verify the patency of large-bore intravenous access and maintain strict nothing-by-mouth (NPO) status.
The client is prepared for an emergent return to the operating room.
Definitive treatment requires surgery; maintaining NPO status prevents aspiration during anesthesia, and IV access ensures fluid resuscitation capabilities.

Key Concept

Management of a surgical evisceration requires immediate prioritization of actions that reduce intra-abdominal pressure and protect exposed viscera from necrosis before conducting systemic assessments.

A nurse is preparing to perform open suctioning for an adult client with a tracheostomy tube. To minimize the risk of complications such as hypoxia and mucosal trauma, in what order should the nurse perform the following actions? Arrange the steps in the correct sequence.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence for tracheostomy suctioning is to first assess the client's baseline respiratory status, hyperoxygenate to prevent hypoxia, advance the catheter without suction to prevent trauma, apply intermittent suction only while withdrawing the catheter, and finally document the findings.
Following the standard sequence of assessment, pre-oxygenation, careful insertion, active withdrawal suctioning, and documentation ensures that the client's airway is cleared while systematically mitigating the risks of severe hypoxemia and mucosal tissue damage.

Step-by-Step Solution

1
Assess the client's baseline breath sounds and oxygen saturation.
Establishes a baseline for comparison.
Risk reduction begins with obtaining accurate baseline data to determine the necessity of the procedure.
2
Hyperoxygenate the client with 100% oxygen.
Increases alveolar oxygen reserves.
Prevents procedure-induced hypoxia, a critical risk during airway clearance.
3
Advance the catheter into the tracheostomy tube without applying suction.
Positions the catheter safely near the carina.
Prevents severe tissue trauma to the mucosal lining.
4
Apply intermittent suction while rotating and withdrawing the catheter.
Clears mucus and respiratory secretions.
Safely removes secretions while minimizing airway damage.
5
Document the characteristics of the secretions and the client's response.
Completes the medical record.
Ensures continuity of care and legal documentation of the therapeutic procedure.

While a nurse is changing the needleless connector caps on a 65-year-old client's right subclavian central venous catheter, the client suddenly gasps for air, reports sharp chest pain, and develops peripheral cyanosis. Recognizing the signs of a potential air embolism, in what order should the nurse perform the following emergency interventions? Arrange the steps from first priority to last priority.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence of actions for a suspected central line air embolism is to first clamp the catheter, then position the client in a left lateral Trendelenburg position, followed by administering 100% oxygen, activating the rapid response team, and finally continuously monitoring vital signs.
In the event of a suspected air embolism from a central venous catheter, priority interventions follow the principles of source control and preventing further physiological harm. The nurse must first clamp the line to stop the influx of air. Immediately after, the client is placed in a left lateral Trendelenburg position. This is a critical, specific intervention that uses gravity and buoyancy to keep the air bubble in the apex of the right ventricle, preventing it from migrating into the pulmonary arterial bed and causing a fatal outflow obstruction. Once the air is trapped, administering 100% oxygen is the next priority to treat hypoxia and create a nitrogen gradient that helps dissolve the bubble. Only after these immediate, life-saving physical maneuvers are complete should the nurse activate the rapid response team and prepare for further deterioration, as taking time to call for help first could allow the embolus to migrate fatally.

Step-by-Step Solution

1
Clamp the central venous catheter.
Halts further introduction of air into the venous circulation.
When an air embolism is suspected, the immediate priority is to eliminate the source to prevent the embolus from becoming larger and more lethal.
2
Place the client in a left lateral Trendelenburg position.
Traps the air in the right side of the heart.
This specific gravitational positioning prevents the air bubble from traveling through the right ventricle into the pulmonary artery, averting a catastrophic right ventricular outflow tract obstruction.
3
Administer high-flow 100% oxygen via a non-rebreather mask.
Alleviates hypoxia and reduces the size of the air embolus.
High-concentration oxygen not only treats the resulting hypoxemia but also establishes a nitrogen diffusion gradient that accelerates the resorption of the air bubble, which is primarily composed of nitrogen.
4
Activate the rapid response team and notify the healthcare provider.
Summons advanced medical assistance.
After immediate life-saving physical interventions are complete, the nurse must quickly mobilize the medical team for further stabilization, such as potential needle aspiration of the air or transfer to the ICU.
5
Obtain continuous vital signs and prepare equipment for possible intubation.
Ensures readiness for physiological deterioration.
The client remains critically unstable and may rapidly progress to cardiopulmonary arrest. Continuous monitoring and preparation for advanced airway management are essential while awaiting the rapid response team.

Key Concept

Management of a Central Line-Associated Air Embolism requires immediate cessation of air entry, specialized positioning to prevent pulmonary obstruction, and oxygen therapy to shrink the embolus.
Question 668Question →

A nurse is preparing to administer a unit of packed red blood cells (PRBCs) to a client with symptomatic anemia. Arrange the following actions in the correct chronological sequence to ensure safe administration.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence is to first verify the prescription and consent, then assess IV patency and baseline vital signs, followed by obtaining the blood from the blood bank. Afterward, perform the two-nurse bedside verification, and finally, initiate the transfusion slowly.
Safe administration of blood products requires a strict, logical sequence to prevent life-threatening errors and product waste. The nurse must first ensure authorization (prescription and consent). Next, the nurse must ensure the client is physically ready (patent IV and stable baseline vitals) before obtaining the blood, because PRBCs must be hung within 30 minutes of leaving the blood bank. After retrieving the blood, the nurse must perform the mandatory two-nurse verification at the bedside to ensure exact compatibility. Finally, the transfusion is started slowly while the nurse remains with the client for the first 15 minutes to monitor for acute severe reactions.

Step-by-Step Solution

1
Verify the healthcare provider's prescription and confirm informed consent.
Legal and medical authorization is confirmed.
Blood administration requires explicit consent due to the risk of severe reactions and transmission of infectious diseases.
2
Assess the patency of the IV catheter and obtain baseline vital signs.
The client's physical readiness to receive the transfusion is established.
If IV access fails or the client has an elevated temperature, the transfusion cannot proceed. Blood must be returned to the blood bank if not hung within 30 minutes, so readiness must be verified before retrieval.
3
Obtain the unit of PRBCs from the blood bank.
The blood product is brought to the clinical unit.
The blood must be retrieved only when the client is fully prepared to receive the transfusion immediately.
4
Perform a joint verification with another registered nurse at the bedside.
The correct blood product is verified for the correct client.
Strict two-nurse verification is the primary safeguard against fatal ABO incompatibility errors.
5
Initiate the transfusion slowly and remain with the client for 15 minutes.
The transfusion begins safely, and the client is monitored during the highest-risk period.
Most life-threatening transfusion reactions occur within the first 15 minutes or first 50 mL of the infusion.

A nurse is caring for a client who is receiving a transfusion of packed red blood cells. Fifteen minutes after the transfusion begins, the client suddenly reports severe lower back pain, chills, and dyspnea. Place the following nursing interventions in the correct order of priority from first to last.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence is to first stop the transfusion, then maintain intravenous access with normal saline using new tubing, assess the client's vital signs, notify the healthcare provider, and finally send the blood products back to the blood bank.
In an acute hemolytic or allergic transfusion reaction, the priority follows a strict physiological adaptation protocol. The absolute highest priority is stopping the source of harm (the blood). The second priority is maintaining vascular access with new tubing to avoid flushing more blood into the client. Once the line is secure, the nurse assesses the client to determine the extent of the physiological compromise. This assessment data is then communicated to the healthcare provider to obtain emergency prescriptions. Returning the blood bag for diagnostic analysis is an administrative task that occurs last.

Step-by-Step Solution

1
Stop the transfusion immediately.
The infusion of the potentially incompatible blood product is halted.
This is the most critical step to prevent further antigen exposure and minimize the severity of the reaction.
2
Disconnect tubing and start 0.9% sodium chloride with new tubing.
Intravenous access is maintained with a neutral fluid.
It ensures a route for emergency medications is open while preventing the remaining blood in the old tubing from being pushed into the client.
3
Assess vital signs and respiratory status.
Baseline data on the severity of the reaction is obtained.
The nurse needs current hemodynamic data (blood pressure, heart rate, oxygenation) to provide a complete SBAR report to the provider.
4
Notify the healthcare provider and blood bank.
Medical intervention is initiated and the facility's reaction protocol is activated.
The provider must prescribe subsequent treatments (e.g., antihistamines, corticosteroids, or vasopressors).
5
Return the blood bag and tubing to the blood bank.
The offending blood product is secured for laboratory investigation.
The blood bank must analyze the remaining blood and tubing to identify the exact cause of the adverse reaction.

A registered nurse is preparing to apply knee-length anti-embolism stockings to a client who is on strict bed rest. Place the following nursing actions in the correct order from first to last. (All steps are required.)

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence begins with measuring the client's legs to ensure proper sizing, followed immediately by elevating the legs to promote venous drainage. The nurse then prepares the stocking by turning it inside out, applies it over the foot and heel, and finally smooths it up the calf to prevent wrinkles.
The correct sequence ensures that stockings provide optimal therapeutic benefit. Proper sizing and pre-elevation of the legs prevent the trapping of venous blood. The specific inside-out application technique minimizes friction and prevents skin shearing during application, while smoothing the fabric prevents dangerous tourniquet effects.

Step-by-Step Solution

1
Measure the client's calf circumference and leg length to determine the appropriate stocking size.
Secures the correct fit for the client's specific anatomy.
Accurate sizing is required prior to application to ensure therapeutic compression without restricting arterial flow.
2
Place the client in a supine position and elevate the legs for 15 to 30 minutes.
Empties engorged superficial veins.
Applying compression stockings while blood is pooled in the lower extremities traps venous blood and can promote, rather than prevent, thrombus formation.
3
Insert a hand into the stocking, grasp the heel pocket, and turn the stocking inside out.
Inverts the stocking down to the heel section.
This specific technique allows the stocking to be rolled smoothly onto the leg rather than bunched up, minimizing skin shearing.
4
Slide the foot portion of the stocking smoothly over the client's toes and heel.
Anchors the stocking correctly on the distal extremity.
Aligning the heel patch exactly over the client's heel prevents localized friction and pressure ulcers.
5
Pull the remaining fabric up over the calf and smooth out any wrinkles.
Completes the application process with uniform compression.
Wrinkles, folds, or rolled top edges act as a tourniquet, cutting off venous return and increasing the risk of deep vein thrombosis.

Question 671Question →

A charge nurse at a skilled rehabilitation center responds to a room where an 84-year-old client is experiencing a sudden, acute onset of severe confusion and hyperactivity, which is a stark change from their baseline. Arrange the following nursing actions in the priority order they should be implemented.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence is to first ensure safety, then obtain vital signs and blood glucose, conduct a focused physical assessment, review the medication record, and finally notify the healthcare provider.
In the aging process, sudden and acute confusion is not normal; it indicates delirium, which is a medical emergency often caused by an underlying physiological issue. According to nursing prioritization frameworks, the nurse must first establish immediate safety for a hyperactive client. Next, the nurse assesses basic physiological parameters (vital signs, oxygenation, and blood glucose) to rule out life-threatening causes like hypoxia or hypoglycemia. Once these are stable, the nurse performs a focused physical assessment for other common triggers in older adults, such as urinary retention or infection. Reviewing the medication record for iatrogenic causes follows direct bedside client assessment. Finally, armed with comprehensive data, the nurse notifies the healthcare provider to facilitate prompt medical intervention.

Step-by-Step Solution

1
Ensure the immediate physical safety of the client and remove potential environmental hazards.
The client is protected from immediate self-harm or injury.
Prioritization frameworks dictate that acute safety threats must be addressed first, particularly for hyperactive and disoriented clients.
2
Obtain current vital signs, oxygen saturation, and a capillary blood glucose reading.
Critical physiological baselines are established.
Assessing airway, breathing, circulation, and blood glucose identifies immediate, life-threatening causes of delirium such as hypoxia or hypoglycemia.
3
Assess for acute physical triggers such as a distended bladder, fecal impaction, or localized pain.
Additional common physiological triggers are evaluated at the bedside.
Older adults frequently develop delirium from easily reversible conditions like urinary retention or unrecognized pain.
4
Evaluate the recent medication administration record for newly added pharmacological agents.
Potential iatrogenic causes are identified from the chart.
After completing direct patient care, reviewing the chart for new medications helps complete the clinical picture before notifying the provider.
5
Communicate the comprehensive assessment findings to the attending healthcare provider.
The provider is informed using a complete and structured report.
The provider needs a full set of vital signs, physical findings, and medication history to make an accurate diagnosis and order appropriate medical interventions.

Prioritizing Care for Acute Delirium in Older Adults
Question 672Question →

A nurse is caring for a client newly admitted to the intensive care unit with diabetic ketoacidosis (DKA). The client is lethargic and exhibits deep, rapid respirations. Initial laboratory results reveal a serum blood glucose of 680 mg/dL (37.7 mmol/L), an arterial pH of 7.12, and a serum potassium of 2.7 mEq/L (2.7 mmol/L). In what order should the nurse implement the collaborative interventions? Arrange the actions from first to last.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence is: 1) Initiate 0.9% sodium chloride, 2) Administer potassium chloride, 3) Begin regular insulin infusion, 4) Assess blood glucose hourly, 5) Add 5% dextrose to fluids when glucose reaches 250 mg/dL.
In the management of DKA, restoring intravascular volume with isotonic saline is always the first priority to reverse hypovolemic shock. While standard protocols follow fluid resuscitation immediately with a continuous insulin infusion, this client presents with severe hypokalemia (2.7 mEq/L). Insulin actively transports potassium from the extracellular fluid into the cells. Administering insulin prior to correcting this profound hypokalemia would induce a lethal drop in serum potassium, triggering fatal cardiac arrhythmias. Therefore, potassium replacement is the critical second step and must strictly precede the insulin infusion. Once potassium is suitably replaced (>3.3 mEq/L), regular insulin is initiated to halt ketogenesis and lower glucose. Because IV insulin rapidly alters glucose levels, hourly monitoring is mandatory. Finally, when the blood glucose approaches 250 mg/dL, 5% dextrose is added to the maintenance fluids to prevent a rapid fluid shift into the brain (cerebral edema) and to avoid iatrogenic hypoglycemia.

Step-by-Step Solution

1
Analyze the client's laboratory values and clinical presentation.
The client has severe DKA complicated by critical hypokalemia (potassium 2.7 mEq/L).
Identifying critical values alters the standard DKA algorithm, specifically regarding the timing and safety of continuous insulin administration.
2
Identify the most immediate life-threatening physiological deficit.
Profound dehydration and hypovolemia are the most immediate threats to systemic perfusion.
Initial fluid resuscitation with isotonic saline (0.9% NaCl) is required to restore blood pressure and vital organ perfusion before addressing the underlying metabolic derangements.
3
Determine the safety of initiating insulin therapy.
Insulin therapy is currently contraindicated due to the serum potassium level being critically below 3.3 mEq/L.
Insulin facilitates the intracellular shift of both glucose and potassium. Administering insulin to a severely hypokalemic client will rapidly lower intravascular potassium further, risking lethal cardiac arrhythmias. Potassium replacement must occur first.
4
Sequence the remaining metabolic interventions.
Insulin is started after potassium is replaced, followed by strict monitoring and eventually adding dextrose.
Once potassium is safe, insulin corrects the acidosis. Hourly glucose monitoring ensures safe titration. Dextrose is added at 250 mg/dL to prevent cerebral edema from rapid osmolality shifts.

A nurse is preparing to administer a large-volume cleansing enema to an adult client who is experiencing severe constipation. In what order should the nurse perform the following actions? Arrange the steps in the correct sequence.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence is to position the client on their left side, lubricate the tubing, gently insert the tube while the client exhales, initiate the fluid flow with the bag held at hip level, and finally elevate the bag to the appropriate height.
Safe and effective enema administration requires following a sequence that minimizes discomfort and maximizes fluid retention. The left lateral Sims' position is established first because it aligns with the anatomy of the descending colon. Next, lubrication is applied to prevent mucosal injury. Having the client exhale relaxes the sphincter for smooth insertion of the tube. Once inserted, initiating the flow with the bag at hip level prevents a sudden surge of fluid. Finally, gradually raising the bag to a maximum of 12 to 18 inches provides the appropriate hydrostatic pressure for instillation without causing severe bowel spasms.

Step-by-Step Solution

1
Assist the client into the left lateral Sims' position.
The client's anatomy is aligned for gravity-assisted fluid flow.
This position exposes the anus and allows fluid to flow naturally into the descending colon.
2
Lubricate the distal tip of the rectal tube.
The tube is prepared for smooth insertion.
Water-soluble lubricant prevents tissue trauma and friction against the delicate rectal mucosa.
3
Insert the tube 3 to 4 inches while the client exhales.
The tube passes the internal sphincter safely.
Exhalation relaxes the sphincter, and the depth ensures fluid enters the rectum rather than leaking out.
4
Open the clamp with the container held at hip level.
Fluid begins to flow slowly into the rectum.
Low initial pressure prevents a sudden surge of fluid that could trigger immediate cramping and expulsion.
5
Elevate the container 12 to 18 inches above the anus.
A steady, controlled flow rate is established.
This height provides optimal hydrostatic pressure for a high enema without causing excessive bowel distention.

The client is experiencing acute anaphylaxis, a rapid decompensation state characterized by airway compromise.
Recognizing the life-threatening nature of the allergic reaction dictates the speed and prioritization of interventions.
2
Determine the absolute first action to mitigate the cause.
Discontinuing the intravenous antibiotic infusion.
Further exposure to the antigen must be halted immediately to prevent the anaphylactic cascade from worsening.
3
Apply the ABC (Airway, Breathing, Circulation) prioritization framework.
Ensure a patent airway and apply supplemental oxygen.
Airway edema and bronchoconstriction are immediate life threats that take precedence over all other secondary actions.
4
Determine the next step for acquiring advanced medical support.
Activate the facility's rapid response system.
Additional personnel and advanced airway equipment may be required rapidly if the client's condition continues to deteriorate.
5
Provide definitive pharmacological intervention.
Administer intramuscular epinephrine.
Epinephrine is the definitive treatment for anaphylaxis, reversing vasodilation and bronchoconstriction, and should be administered per emergency protocol.

A nurse is caring for a client who is two days postoperative following an open exploratory laparotomy. The client coughs forcefully and reports a sudden "popping" sensation in the abdomen. The nurse assesses the surgical site and observes an evisceration. In which order should the nurse perform the following actions to reduce the client's risk of complications? Arrange the actions in chronological order from first to last.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence is to call for help, position the client, cover the organs, assess vital signs, notify the surgeon, and prepare for surgery.
The correct sequence prioritizes immediate client safety and organ viability. The nurse must first secure help to obtain supplies without abandoning the client. Next, placing the client in a low-Fowler's position with bent knees immediately reduces abdominal tension to prevent further evisceration. Once supplies arrive, covering the exposed organs with sterile, moist dressings is critical to prevent necrosis. Only after the organs are protected should the nurse assess vital signs to evaluate for shock. This assessment provides necessary data for the subsequent step of notifying the surgeon. Finally, the nurse prepares the client for definitive emergency surgery.

Step-by-Step Solution

1
Remain with the client and delegate a colleague to gather sterile supplies.
Immediate assistance is secured without abandoning the client.
The nurse must never leave a client with an evisceration due to the high risk of rapid physiological deterioration.
2
Position the client in a low-Fowler's position with the knees flexed.
Tension on the abdominal musculature is reduced.
This positioning prevents further protrusion of the viscera by relaxing the abdominal wall.
3
Cover the protruding internal organs with sterile dressings moistened with sterile normal saline.
The exposed viscera are protected from the environment.
Preventing bowel drying, ischemia, and necrosis is the most urgent physiological priority once supplies are available.
4
Assess the client's vital signs and peripheral perfusion.
The client's hemodynamic status is established.
Monitoring for hypovolemic shock provides critical baseline data needed before contacting the provider.
5
Communicate the assessment findings and the clinical emergency to the surgeon.
The surgical team is activated.
The surgeon needs the current vital signs and the exact clinical situation to initiate emergency surgical protocols.
6
Maintain the client's NPO status and prepare for immediate surgical intervention.
The client is readied for the operating room.
The definitive treatment for an evisceration is surgical closure.

Key Concept

Emergency management of surgical wound evisceration requires immediate interventions to reduce tension and protect organ viability before assessment and notification.

A nurse accidentally drops a specimen tube, resulting in a small blood spill on the floor of the clinical utility room. Arrange the following actions in the correct sequence for safely cleaning up this biohazardous material.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence for cleaning up a biohazard spill is to first don protective gloves, absorb the initial spill, discard the soiled materials into a biohazard bag, apply a proper hospital disinfectant, and allow it to sit for the required contact time.
According to OSHA and CDC guidelines for handling biohazardous spills, healthcare workers must first protect themselves by donning gloves. Next, the bulk of the infectious material must be contained and removed using absorbent materials. These materials are immediately disposed of in a biohazard container. Only after the gross contamination is removed should the surface be sprayed with a chemical disinfectant, which must then remain wet for the manufacturer's recommended contact time to ensure complete eradication of bloodborne pathogens.

Step-by-Step Solution

1
Put on a pair of clean disposable gloves.
The nurse's hands are protected from bloodborne pathogens.
Standard precautions mandate wearing personal protective equipment before potential exposure to body fluids.
2
Cover the spill with absorbent paper towels or a spill kit powder.
The fluid is contained and fully absorbed.
Absorbing the bulk of the spill prevents the fluid from spreading and makes it safe to lift.
3
Discard the saturated absorbent materials into a designated red biohazard bag.
The infectious gross waste is safely contained.
Blood-soaked items meet the criteria for regulated medical waste and require specific disposal.
4
Apply an EPA-registered hospital disinfectant to the contaminated surface.
The floor surface is chemically treated.
Applying disinfectant directly to the cleaned surface targets any residual microscopic pathogens.
5
Allow the disinfectant to remain on the surface for the required contact time.
The area is completely and safely decontaminated.
Chemical disinfectants need adequate time to effectively eradicate pathogens before the area is wiped or air-dried.

Question 678Question →

An oncology nurse is planning care for four assigned clients after receiving the morning handoff report. Based on the principles of prioritization, arrange the clients in the order the nurse should assess them, from first to last.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct order of prioritization is: first, the client with sudden shortness of breath after central line placement; second, the neutropenic client with a new fever; third, the client with severe lower back pain; and fourth, the client with expected chronic findings of terminal lung cancer.
The priority sequence follows the ABC framework and the principle of acute over chronic. The client with a new-onset breathing complication post-procedure (pneumothorax risk) is the most critical. Next is the neutropenic client with a fever, who is at high risk for fatal sepsis. The third priority is the client experiencing severe acute pain, which is distressing but not immediately life-threatening. Finally, the client with terminal lung cancer presents with chronic, expected findings and is the most stable.

Step-by-Step Solution

1
Identify the framework for prioritization.
Use the Airway, Breathing, Circulation (ABC) and the acute versus chronic principles.
These frameworks determine which client has the most immediate, life-threatening condition.
2
Evaluate each client for immediate ABC threats.
The client with sudden shortness of breath after a subclavian central venous catheter placement has a potential breathing compromise (pneumothorax).
Airway and breathing are the highest priorities and require immediate life-saving intervention.
3
Evaluate the remaining clients for acute, unstable conditions.
The neutropenic client with a new fever is highly unstable and at risk for rapid progression to septic shock.
Infection in heavily immunocompromised clients is a critical circulatory risk that takes precedence over pain management.
4
Differentiate between acute needs and chronic/expected findings in the final two clients.
The client with severe bone pain requires acute symptom management, while the lung cancer client has expected baseline findings.
Acute, distressing symptoms like severe pain require intervention before evaluating stable clients with chronic conditions.

Key Concept

Establishing priorities involves addressing ABC (Airway, Breathing, Circulation) threats first, followed by highly unstable conditions (such as neutropenic sepsis risk), then urgent symptom management (such as acute pain), and finally chronic or expected findings.

A nurse is preparing a client for discharge. While reviewing the printed discharge packet with the client in their room, the nurse realizes that another client's sensitive laboratory results were mistakenly stapled into the packet. Arrange the actions the nurse should take in the correct priority order.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence is to first secure the breached information by retrieving the incorrect documents, explain the error to the client, provide the correct discharge documents, notify nursing leadership and the privacy officer, and finally complete an internal incident report.
The nursing process and prioritization frameworks dictate that immediate mitigation of harm (retrieving the PHI) takes precedence over all other administrative actions. After containing the active breach, the nurse must address the client's immediate needs by explaining the error and providing the correct documents. Only once client-facing care and immediate security are resolved should the nurse escalate the issue to leadership (privacy officer) and complete the required administrative documentation (incident report).

Step-by-Step Solution

1
Retrieve the incorrect laboratory results from the client's discharge packet immediately.
The unauthorized disclosure is immediately halted.
Prioritization frameworks dictate that mitigating immediate harm and securing Protected Health Information (PHI) is the first required action during a breach.
2
Explain the clerical error to the client without disclosing the other client's identity.
The client understands the situation without further privacy violations occurring.
Immediate, transparent communication addresses the situation professionally while upholding the third party's confidentiality.
3
Provide the client with their correct discharge documents and complete the discharge teaching.
The client's discharge process continues safely.
Once the breach is contained, the nurse must ensure the client receives their own correct health information to prevent adverse clinical outcomes.
4
Notify the charge nurse and the facility's privacy officer regarding the unauthorized disclosure.
Facility leadership is made aware of the HIPAA violation.
Administrative reporting to leadership initiates the facility's official breach response and compliance protocol.
5
Complete an internal facility incident report detailing the confidentiality breach.
A formal risk management record of the variance is created.
Filing an incident report is required for regulatory compliance and quality improvement, but should only be done after immediate safety and clinical needs are addressed.

Question 680Question →

A nurse on a medical-surgical unit realizes they have just administered a full dose of an immediate-release antihypertensive medication to the wrong client. Arrange the following actions in the priority order the nurse should perform them. (Place the first and most urgent action at the top, and the final administrative action at the bottom.)

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence is to first assess the client, then notify the healthcare provider, inform the charge nurse, document the clinical event in the medical record, and finally complete the institutional incident report.
Following any clinical error, the nursing process dictates that assessment is always the first step. The nurse must determine if the client has been harmed. Next, the provider is notified so medical interventions can be ordered. Informing the charge nurse follows the chain of command. Clinical documentation occurs next to maintain an accurate health record. Finally, the incident report is completed as an internal administrative task, completely separate from the client's medical record.

Step-by-Step Solution

1
Assess the client's vital signs and current physiological status.
Establishes the client's baseline condition and identifies immediate adverse effects.
Direct client care and physiological safety always take priority over communication and paperwork.
2
Notify the healthcare provider of the medication error.
Allows the provider to give necessary orders based on the nurse's assessment.
Medical intervention may be required immediately to counteract the medication.
3
Inform the unit charge nurse or nursing supervisor.
Engages unit leadership in the event.
Leadership needs to be aware for patient monitoring, risk management escalation, and supporting the nurse.
4
Document the administered medication and provider notification in the medical record.
Creates a legal, clinical record of the objective facts.
Clinical documentation must reflect what actually occurred and what assessments were made.
5
Complete an institutional incident or variance report.
Fulfills administrative and risk-management requirements.
This is purely administrative, does not affect immediate patient outcomes, and must be kept separate from the clinical chart.
