Question 761Question →

An adult client who underwent an open reduction and internal fixation of the right femur 48 hours ago suddenly develops extreme restlessness and shortness of breath. The nurse assesses the client and records the following vital signs: temperature 37.4°C (99.3°F), heart rate 126 beats/min, respirations 32 breaths/min, and blood pressure 114/72 mm Hg. The oxygen saturation is 85% on room air. A stat arterial blood gas (ABG) reveals a pH of 7.52, PaCO2 of 28 mm Hg, PaO2 of 53 mm Hg, and HCO3- of 23 mEq/L. Based on these findings, what is the priority nursing action?

Show answer & explanation

Answer: Apply a high-concentration oxygen delivery device and activate the rapid response team.

Answer

The priority is to apply a high-concentration oxygen delivery device and activate the rapid response team.
The clinical picture of acute-onset restlessness, severe hypoxia, and uncompensated respiratory alkalosis in a post-operative long bone fracture client strongly suggests a life-threatening pulmonary or fat embolism. The priority is to immediately address the profound hypoxemia with high-flow oxygen and activate the rapid response team to escalate medical management.

Step-by-Step Solution

1
Analyze the clinical presentation and context.
The client is 48 hours post-femur fracture repair and presents with acute-onset restlessness, tachypnea, tachycardia, and severe hypoxia, suggesting a pulmonary embolism or fat embolism.
Identifying the likely etiology guides the urgency and type of intervention required.
2
Interpret the arterial blood gas (ABG) results.
pH 7.52 (alkalosis), PaCO2 28 mm Hg (low, indicating respiratory cause), PaO2 53 mm Hg (severe hypoxemia), HCO3- 23 mEq/L (normal). Interpretation: Uncompensated respiratory alkalosis with severe hypoxemia.
Accurate ABG interpretation distinguishes between primary respiratory failure, compensatory hyperventilation, and metabolic disturbances.
3
Determine the priority nursing intervention based on the physiological data.
The respiratory alkalosis is a compensatory response to the life-threatening hypoxemia. The immediate need is to restore oxygenation and escalate care.
Addressing the root cause of the compromised airway and breathing takes precedence according to the ABC (Airway, Breathing, Circulation) framework.

Key Concept

Prioritization of care for acute hypoxemic respiratory failure and uncompensated respiratory alkalosis related to a suspected pulmonary or fat embolism.
Question 762Question →

A nurse is preparing to perform a sterile dressing change on a client's central venous catheter (CVC). To reduce the risk of a central line-associated bloodstream infection (CLABSI) and prevent catheter dislodgment, place the following steps in the correct chronological order.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence begins with donning a mask and directing the client's face away, followed by removing the old dressing. The nurse then transitions to sterile gloves, cleanses the site with chlorhexidine (allowing it to dry), and finally applies a new transparent occlusive dressing.
Changing a central line dressing requires strict adherence to sterile technique to prevent CLABSI. Masking protects the site from respiratory droplets. The old dressing is removed carefully toward the site to prevent dislodging the catheter. A sterile field is then established by donning sterile gloves. Chlorhexidine is applied with friction to destroy microorganisms and must dry completely to achieve its chemical antisepsis effect. Finally, a sterile occlusive dressing seals the site.

Step-by-Step Solution

1
Don a face mask and instruct the client to turn their head away.
Respiratory droplets are directed away from the vulnerable area.
Applying airborne precautions reduces the immediate risk of bacterial contamination from the respiratory tract before the protective dressing is even removed.
2
Remove the old dressing by pulling the edges toward the insertion site.
The insertion site is safely exposed.
Pulling away from the insertion site could snag the catheter and accidentally pull it out. This step utilizes clean technique.
3
Discard the old dressing and clean gloves, perform hand hygiene, and don sterile gloves.
The nurse successfully transitions to strict sterile technique.
Once the site is exposed, maximum sterile barrier precautions are required to touch the site and apply the new antiseptic and dressing.
4
Scrub the insertion site with chlorhexidine using friction and allow it to air dry.
Skin flora and potential pathogens are eradicated.
Friction helps the antiseptic penetrate the epidermis, and chlorhexidine must air dry completely to achieve its maximum antimicrobial efficacy.
5
Apply a new sterile transparent occlusive dressing over the insertion site.
The catheter site is securely sealed.
An occlusive transparent dressing prevents environmental contamination while allowing continuous visualization of the site for early signs of infection.

Question 763Question →

During a routine intravenous (IV) tubing change for a client's central venous catheter (CVC), the catheter hub accidentally becomes disconnected and is left open to room air. The client abruptly gasps for breath, begins coughing violently, and reports acute, sharp chest pain. The client's lips appear cyanotic and oxygen saturation drops to 81%. What is the priority nursing action?

Show answer & explanation

Answer: Clamp the catheter immediately and place the client in a left lateral Trendelenburg position.

Answer

The correct action is to immediately clamp the catheter and position the client in a left lateral Trendelenburg position.
Clamping the catheter immediately stops further air entry. Placing the client in a left lateral Trendelenburg position is the standard emergency medical intervention for an air embolism, as it traps the air in the right ventricle and prevents it from occluding the pulmonary circulation.

Step-by-Step Solution

1
Identify the complication.
Recognize that an open central venous catheter hub accompanied by sudden, severe respiratory distress indicates a life-threatening air embolism.
Air rapidly enters the venous system due to negative intrathoracic pressure during inspiration.
2
Stop the source.
Clamp the central venous catheter.
Clamping the line instantly prevents any additional air from being drawn into the client's central circulation.
3
Position the client appropriately.
Place the client in the left lateral Trendelenburg position.
This specific position utilizes gravity to trap the air bubble in the apex of the right ventricle, preventing it from migrating forward into the pulmonary artery and causing a right ventricular outflow tract obstruction.

Question 764Question →

During afternoon rounds on a surgical unit, a client who had a partial colectomy two days ago reports feeling increasingly restless and unable to get comfortable. The assessment reveals a temperature of 98.4°F (36.9°C), a heart rate of 114 beats per minute, a blood pressure of 104/84 mm Hg, and a respiratory rate of 22 breaths per minute. The client's skin is cool to the touch and peripheral pulses are weak. Which of the following is the priority nursing action?

Show answer & explanation

Answer: Examine the surgical incision site and the drainage collection device for signs of active bleeding

Answer

The highest priority action is to examine the surgical incision site and drainage collection device for signs of active bleeding.
The client is exhibiting classic signs of the compensatory stage of hypovolemic shock, which include a narrowing pulse pressure (20 mm Hg), tachycardia, tachypnea, unexplained restlessness, and cool skin due to peripheral vasoconstriction. Because this client is only two days postoperative, internal hemorrhage is a high-risk complication. The priority is to assess for the source of bleeding (such as the incision and drains) so that the healthcare provider can be alerted and fluid resuscitation can begin.

Step-by-Step Solution

1
Analyze the client's vital signs and physical assessment findings.
The client presents with tachycardia (114 bpm), a narrow pulse pressure (104 - 84 = 20 mm Hg), tachypnea (22 breaths/min), restlessness, and cool skin.
Identifying abnormal physiological trends is the first step in recognizing clinical deterioration.
2
Correlate the findings with potential postoperative complications.
The combination of these specific signs strongly indicates the compensatory stage of hypovolemic shock, likely due to internal hemorrhage.
The sympathetic nervous system activates to maintain cardiac output through vasoconstriction (narrow pulse pressure, cool skin) and tachycardia.
3
Determine the highest priority nursing intervention.
The nurse must immediately assess for the source of the suspected bleeding to initiate appropriate medical management.
According to the ABCs (Airway, Breathing, Circulation), addressing a severe circulation deficit takes precedence over routine symptom management or delegation.

A nurse is preparing to administer prescribed intravenous (IV) push ondansetron to a client experiencing postoperative nausea. The client has a dedicated peripheral IV saline lock in place. Arrange the following actions in the correct sequence for safe administration.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence follows the SAS (Saline, Administer, Saline) method while maintaining asepsis and preventing catheter occlusion.
The correct sequence for administering an IV push medication through a saline lock is to first clean the port to maintain asepsis. Next, use the SAS method: check patency with normal saline (Saline), administer the medication at the proper rate (Administer), and flush again with normal saline to push the remaining medication at that exact same safe rate (Saline). Finally, clamp the line with positive pressure to prevent blood reflux and subsequent occlusion.

Step-by-Step Solution

1
Scrub the hub with antiseptic.
Port is disinfected.
Maintains asepsis and prevents catheter-associated bloodstream infections.
2
Aspirate and flush with normal saline.
Patency is confirmed.
Ensures the IV is properly located in the vein and clears the line.
3
Administer the IV push medication.
Medication is delivered safely.
Provides therapeutic intervention at the safe, prescribed administration rate.
4
Flush with normal saline at the same administration rate.
Medication is fully cleared from the extension tubing.
Ensures the entire dose reaches the client without inadvertently pushing a rapid bolus of the medication left in the tubing dead space.
5
Clamp while applying positive pressure.
System is sealed.
Prevents blood reflux into the catheter, avoiding occlusion.

A nurse is caring for a client admitted with an exacerbation of heart failure. The client suddenly develops severe dyspnea, extreme anxiety, and begins coughing up pink, frothy sputum. Arrange the following nursing actions in the priority order they should be performed.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct priority sequence is to first place the client in a high Fowler's position, followed by administering high-flow oxygen, obtaining vital signs, administering intravenous furosemide, and finally inserting an indwelling urinary catheter.
In acute pulmonary edema, the absolute priority is airway and breathing. Placing the client in a high Fowler's position immediately reduces venous return and eases breathing. Oxygen is applied next to treat hypoxia. Once ABCs are stabilized, baseline vital signs must be taken to safely administer medications. Intravenous furosemide is then given to pull fluid from the lungs, followed by the insertion of a urinary catheter to closely monitor the diuresis.

Step-by-Step Solution

1
Evaluate the immediate threat to life based on the presentation.
The client has developed acute pulmonary edema, compromising airway and breathing.
To determine the immediate ABC (Airway, Breathing, Circulation) priority.
2
Implement rapid mechanical intervention for breathing.
Place the client upright with dependent legs.
This physical action immediately decreases venous return to the heart and reduces pulmonary congestion and the work of breathing.
3
Treat the resultant hypoxemia.
Administer high-flow oxygen.
Improves alveolar gas exchange that has been severely impaired by fluid accumulating in the alveoli.
4
Establish a clinical baseline.
Assess vital signs and auscultate lung sounds.
Provides necessary hemodynamic data (such as blood pressure and heart rate) prior to medication administration.
5
Implement pharmacological treatment.
Administer intravenous furosemide.
Promotes rapid diuresis to decrease overall circulating blood volume and further relieve pulmonary congestion.
6
Monitor therapeutic response.
Insert an indwelling urinary catheter.
Allows accurate measurement of urine output to evaluate the effectiveness of the loop diuretic.

Key Concept

Prioritization of care in acute pulmonary edema focuses on the ABCs: optimizing breathing mechanics and oxygenation before proceeding to assessment and pharmacological interventions.
Question 767Question →

A nurse is caring for a client who is receiving continuous total parenteral nutrition (TPN) through a dedicated lumen of a multi-lumen central venous catheter (CVC). The healthcare provider prescribes a scheduled dose of an intravenous (IV) antibiotic. Which of the following actions is the most appropriate for the nurse to take when administering the medication?

Show answer & explanation

Answer: Administer the antibiotic through an alternate, available lumen of the central venous catheter.

Answer

The nurse should administer the antibiotic through an alternate, available lumen of the central venous catheter.
Total parenteral nutrition (TPN) solutions have a very high glucose and nutrient concentration, making them highly susceptible to both chemical incompatibility and bacterial contamination. Consequently, standard nursing practice mandates that TPN must be infused through a strictly dedicated line or a dedicated lumen of a multi-lumen catheter. Because the client has a multi-lumen central venous catheter, the nurse can safely administer the antibiotic through a separate, available lumen. The separate lumens allow incompatible fluids to enter the central bloodstream independently, where high blood flow instantly dilutes them.

Step-by-Step Solution

1
Assess the current intravenous access and the prescribed therapies.
The client has a multi-lumen central venous catheter with one lumen dedicated to TPN, and requires IV antibiotic administration.
Understanding the available access determines the safest route for new intravenous medications without compromising existing infusions.
2
Identify the safety principles regarding TPN administration.
TPN must always run through a strictly dedicated line or lumen to prevent precipitation, chemical incompatibility, and infection.
The hypertonic, complex nature of TPN makes it highly reactive with other medications.
3
Select the intervention that preserves the dedicated TPN line while safely delivering the antibiotic.
Utilizing a separate, available lumen on the existing multi-lumen catheter achieves both goals.
Multi-lumen catheters are designed to infuse incompatible solutions simultaneously, as the lumens exit at different points in the high-flow central venous system.

A nurse is preparing to perform open-system suctioning for a client with a tracheostomy tube. To reduce the risk of hypoxia and mucosal trauma, in which 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 is to preoxygenate, insert without suction, withdraw slightly, apply suction while rotating outward, and finally reassess.
To reduce the risk of life-threatening complications such as hypoxemia, cardiac dysrhythmias, and mucosal trauma, the nurse must adhere to a strict procedural sequence. Preoxygenation provides a critical oxygen reserve. Inserting the catheter without suction protects the airway lining. Withdrawing the catheter slightly before applying suction prevents adherence to the carina, avoiding vagal stimulation. Applying suction only during withdrawal with a rotating motion safely removes secretions. Reassessing the client verifies the procedure's success and the client's stability.

Step-by-Step Solution

1
Preoxygenate the client.
Increases the client's arterial oxygenation levels.
Prevents hypoxemia during the procedure.
2
Insert the catheter without applying suction.
The catheter reaches the level of the carina or mainstem bronchi.
Applying suction during insertion causes severe tissue trauma and oxygen depletion.
3
Withdraw the catheter 1 to 2 centimeters.
The catheter tip is moved away from the sensitive carina.
Prevents direct vagal stimulation and localized tissue damage when suction is applied.
4
Apply intermittent suction while rotating and withdrawing.
Secretions are safely cleared from the airway.
Rotation prevents the catheter tip from continuously adhering to one area of the tracheal mucosa.
5
Reassess the client.
Post-procedure baseline is established.
Ensures the airway is patent and the client has not suffered adverse effects.

An emergency department triage nurse assesses a young adult who sustained blunt abdominal trauma after striking a bicycle handlebar. Over the past 45 minutes, the client's heart rate has trended from 86 to 116 beats per minute, and their blood pressure has shifted from 120/72 mm Hg to 108/86 mm Hg. Based on these physiological changes, what is the priority nursing action?

Show answer & explanation

Answer: Initiate rapid infusion of intravenous isotonic crystalloid fluids.

Answer

The priority action is to initiate a rapid infusion of intravenous isotonic crystalloid fluids.
The client is exhibiting classic signs of the compensatory stage of hypovolemic shock, likely due to internal hemorrhage from the abdominal trauma. As blood volume drops, the sympathetic nervous system triggers an increased heart rate to maintain cardiac output and peripheral vasoconstriction, which raises the diastolic blood pressure and narrows the pulse pressure. The most critical intervention is to aggressively restore intravascular volume with isotonic crystalloids.

Step-by-Step Solution

1
Analyze the vital sign trends.
The heart rate increased significantly (86 to 116 bpm) while the pulse pressure narrowed dramatically (from 48 mm Hg to 22 mm Hg).
Identifying changes in vital signs over time is critical for detecting physiological deterioration before profound hypotension occurs.
2
Correlate the findings with the mechanism of injury.
Blunt abdominal trauma combined with tachycardia and a narrowing pulse pressure indicates compensatory hypovolemic shock (internal bleeding).
The body compensates for lost circulating volume by increasing the heart rate and vasoconstricting, which raises the diastolic blood pressure and narrows the pulse pressure.
3
Determine the priority nursing intervention.
Fluid resuscitation with isotonic crystalloids is required immediately.
In hypovolemic shock, restoring intravascular volume is the primary intervention to maintain cardiac output and tissue perfusion.

Question 770Question →

A nurse is assessing a client who is 2 hours post-cardiac catheterization via the right femoral artery. Which assessment finding is the priority and requires immediate intervention to reduce the risk of a severe complication?

Show answer & explanation

Answer: The client reports a new onset of dull, aching pain in the lower back and right flank.

Answer

The client reports a new onset of dull, aching pain in the lower back and right flank.
Following a cardiac catheterization via the femoral artery, bleeding can occur internally into the retroperitoneal space. Because this space can hold a large volume of blood without obvious external swelling, the earliest clinical indicator is often a new onset of dull, aching pain in the lower back or flank on the operative side. This finding requires immediate intervention, such as applying manual pressure and notifying the healthcare provider, to reduce the risk of profound hypovolemic shock.

Step-by-Step Solution

1
Analyze the procedure and its associated risks.
Cardiac catheterization via the femoral artery carries a high risk of bleeding, specifically retroperitoneal hemorrhage, which can be life-threatening.
Identifying the highest risk complication guides the post-procedure assessment priorities.
2
Evaluate each assessment finding against expected versus abnormal post-procedure outcomes.
Positioning, minor ecchymosis, and slight blood pressure changes are expected. Flank or lower back pain is an abnormal, critical finding.
Differentiating expected physiological findings from abnormal findings is required to identify clinical deterioration.
3
Prioritize the finding that indicates the greatest immediate risk to the client's physiological integrity.
The report of new back and flank pain indicates internal bleeding, requiring immediate provider notification and intervention.
Early intervention for internal hemorrhage prevents progression to hypovolemic shock.

Key Concept

Question 771Question →

A client on an orthopedic unit is three days postoperative following a unilateral knee replacement. The client suddenly reports sharp, localized chest pain upon inspiration accompanied by a feeling of impending doom. Current vital signs reveal a respiratory rate of 32 breaths per minute and an oxygen saturation of 85% on room air. Which of the following concurrent nursing actions are appropriate? Select all that apply.

Select all that apply

Show answer & explanation

Answer: Position the head of the bed at a 60- to 90-degree angle; Apply supplemental oxygen using a high-flow delivery device; Notify the facility's rapid response or emergency medical team

Answer

The correct actions involve elevating the head of the bed, applying supplemental oxygen immediately, and activating the rapid response team.
The client is exhibiting classic signs of an acute pulmonary embolism, a life-threatening medical emergency commonly associated with immobility following major orthopedic surgery. Immediate nursing priorities must focus on optimizing oxygenation and ventilation. Elevating the head of the bed maximizes diaphragmatic excursion and lung expansion. Applying high-flow oxygen directly addresses the severe hypoxia. Because the client is rapidly decompensating and unstable, activating the rapid response team is a critical simultaneous action to secure advanced airway management and initiate hemodynamic support or anticoagulation.

Step-by-Step Solution

1
Analyze the client's postoperative timeline, sudden onset of pleuritic pain, and acute respiratory distress.
Identify that the clinical presentation strongly suggests an acute pulmonary embolism.
Recognizing the underlying life-threatening pathology dictates immediate and appropriate action.
2
Apply the Airway, Breathing, Circulation (ABC) prioritization framework.
Determine that oxygenation and ventilation are the highest priority needs.
The client's hypoxia is severe (85% on room air) and requires immediate reversal to prevent tissue ischemia and cardiovascular collapse.
3
Select interventions that stabilize the client and escalate care concurrently.
Identify high-Fowler's positioning, high-flow oxygen administration, and rapid response activation as the correct simultaneous priorities.
These actions address the immediate physiological crisis while bringing necessary advanced medical support to the bedside.

Question 772Question →

Upon evaluating a client recovering from an extensive small bowel resection, the assigned nurse notes a scheduled order for intravenous pantoprazole. The client's only vascular access is a single-lumen peripherally inserted central catheter (PICC) that is currently delivering total parenteral nutrition (TPN) at 90 mL/hr. How should the nurse proceed with administering the prescribed gastrointestinal protectant?

Show answer & explanation

Answer: Establish a new peripheral intravenous access site specifically for the medication administration.

Answer

The nurse must establish a new peripheral intravenous access site specifically for the medication administration.
Total parenteral nutrition (TPN) is a complex, hypertonic solution that carries an exceptionally high risk for microbial growth and chemical incompatibility when mixed with other pharmacological substances. Evidence-based nursing practice dictates that TPN must be administered through a strictly dedicated intravenous line. Because the client only has a single-lumen PICC currently infusing TPN, the nurse must establish a new, separate peripheral IV line to safely administer the prescribed medication without interrupting the continuous nutritional support or risking precipitation within the central line.

Step-by-Step Solution

1
Analyze the client's current vascular access and active infusions.
The client possesses a single-lumen PICC that is entirely dedicated to a continuous TPN infusion.
Identifying existing access determines whether a new medication can be administered safely through the current line or if alternative access is necessary.
2
Evaluate the safety principles and protocols regarding total parenteral nutrition (TPN).
TPN requires a strictly dedicated line; it cannot be paused for other medications, nor can medications be piggybacked into its tubing.
TPN solutions are complex, highly concentrated mixtures that are prone to chemical incompatibilities. Furthermore, frequently accessing the line significantly increases the risk of dangerous bloodstream infections.
3
Determine the most appropriate and safe nursing intervention for the scheduled medication.
A new peripheral IV catheter must be inserted by a qualified healthcare professional (the RN) to administer the pantoprazole.
This action ensures the scheduled medication is delivered on time while simultaneously preserving the integrity, safety, and continuous flow of the TPN line.

Key Concept

Total parenteral nutrition (TPN) must always be administered through a strictly dedicated intravenous line to prevent severe chemical incompatibilities, catheter occlusion, and life-threatening bloodstream infections.
Question 773Question →

A nurse is evaluating a client who is 11 hour post-percutaneous liver biopsy. The nurse is monitoring the client to reduce the risk of potential complications. Which of the following assessment findings or client actions require IMMEDIATE nursing intervention? (Select all that apply.)

Select all that apply

Show answer & explanation

Answer: The client's heart rate has trended upward from 7676 to 114114 beats per minute over the last 3030 minutes.; The client reports a new onset of sharp pain radiating to the right shoulder.; The client exhibits asymmetrical chest expansion and diminished breath sounds on the right side.

Answer

The findings that require immediate intervention are the upward trend in heart rate, the new sharp pain radiating to the right shoulder, and the asymmetrical chest expansion.
Following a percutaneous liver biopsy, the client is at significant risk for severe complications such as hemorrhage, bile peritonitis, and pneumothorax. An increasing heart rate is a subtle but critical early indicator of hypovolemic shock caused by internal bleeding. New onset of sharp pain radiating to the right shoulder is referred pain that strongly suggests diaphragmatic irritation from accumulating blood or bile. Furthermore, asymmetrical chest expansion with diminished breath sounds on the right side indicates a pneumothorax, which can occur if the pleural cavity was inadvertently punctured during the biopsy. All three of these findings indicate acute physiological decompensation and require immediate life-saving nursing and medical interventions.

Step-by-Step Solution

1
Analyze the clinical scenario and procedure.
The client is 11 hour post-percutaneous liver biopsy, a highly vascular organ located near the pleural cavity.
Identifying the specific procedure helps anticipate the most severe physiological risks, namely hemorrhage, bile leak, and pneumothorax.
2
Evaluate each option for signs of physiological decompensation.
Tachycardia indicates potential shock, right shoulder pain indicates diaphragmatic irritation (bleeding/bile leak), and asymmetrical chest expansion indicates pneumothorax.
Early recognition of shock, peritonitis, or respiratory compromise allows for rapid medical intervention to reduce morbidity.
3
Differentiate between life-threatening abnormalities and expected post-procedure outcomes.
Right-side positioning, normal arterial blood gases, and mild localized soreness are either expected outcomes or therapeutic interventions.
Distinguishing normal from abnormal prevents unnecessary interventions and correctly prioritizes life-saving care.

While monitoring a client receiving an initial unit of packed red blood cells, the nurse notes that 15 minutes into the infusion, the client abruptly reports severe lower back pain, chills, and a sensation of shortness of breath. The client's vital signs reveal a blood pressure of 90/60 mmHg, a heart rate of 116/min, a respiratory rate of 24/min, and a temperature of 101.2°F (38.4°C). Arrange the following nursing actions in the correct order of priority.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

1. Stop the blood transfusion.
2. Disconnect the blood tubing and initiate an infusion of normal saline using new tubing.
3. Assess the client's vital signs and respiratory status.
4. Notify the healthcare provider and the blood bank.
5. Send the remaining blood product and tubing to the blood bank for analysis.
In the event of a suspected acute hemolytic blood transfusion reaction, the absolute first priority is to stop the infusion to prevent further exposure to the incompatible antigen. Once the infusion is stopped, the nurse must maintain a patent IV line for emergency medications by infusing 0.9% sodium chloride using completely new tubing (to avoid pushing residual blood into the client). Next, the nurse performs a rapid physical assessment, including vital signs and respiratory status, to evaluate the severity of the physiological compromise. The nurse then notifies the healthcare provider to obtain emergency prescriptions and alerts the blood bank. Finally, the remaining blood, tubing, and labels are sent back to the blood bank for crossmatching and post-reaction analysis.

Step-by-Step Solution

1
Identify the complication occurring in the clinical scenario.
The client is experiencing a severe acute hemolytic transfusion reaction.
Lower back pain, chills, hypotension, and tachycardia shortly after starting a transfusion are hallmark physiological signs of an acute hemolytic reaction.
2
Determine the absolute first priority action.
Stop the blood transfusion.
The immediate priority in any adverse medication or blood reaction is to remove the causative agent to limit further physiological damage.
3
Determine the next action required to safely maintain venous access.
Disconnect the existing tubing and initiate normal saline using new tubing.
Venous access must be maintained for emergency interventions, but flushing the existing blood tubing would push more incompatible blood into the client.
4
Determine the next action to evaluate the client's condition.
Assess vital signs and respiratory status.
A rapid physiological assessment is necessary to determine the severity of the reaction and to prepare a complete, accurate report for the healthcare provider.
5
Determine the appropriate notification and follow-up protocol steps.
Notify the provider and blood bank, then send the remaining product to the laboratory.
The provider must prescribe emergency pharmacological interventions, and the blood bank must analyze the remaining product and tubing to confirm the reaction etiology.

Question 775Question →

A nurse is managing the parenteral therapies for several clients on a medical-surgical unit. Which of the following nursing actions indicate safe and appropriate practice? (Select all that apply.)

Select all that apply

Show answer & explanation

Answer: Verifying a client's baseline activated partial thromboplastin time (aPTT) and platelet count before initiating a continuous intravenous (IV) heparin infusion.; Hanging an infusion of 10% dextrose in water (D10W) at the same rate when a client's next scheduled bag of total parenteral nutrition (TPN) is temporarily delayed.

Answer

The correct actions are verifying the aPTT and platelet count prior to initiating heparin, and hanging 10% dextrose in water (D10W) when a TPN bag is delayed.
Verifying baseline coagulation values before starting heparin is essential to monitor for therapeutic effect and adverse reactions like heparin-induced thrombocytopenia. Additionally, hanging D10W when TPN is delayed is a standard safety protocol to prevent rebound hypoglycemia caused by the sudden withdrawal of a high-glucose continuous infusion.

Step-by-Step Solution

1
Evaluate the heparin administration action.
Safe practice identified.
Baseline coagulation studies (aPTT, platelets) must be documented before starting systemic anticoagulation to establish a reference point and ensure there are no pre-existing bleeding risks.
2
Calculate the correct insulin pump rate.
Unsafe practice identified.
A concentration of 100 units in 100 mL equates to 1 unit/mL. To deliver 5 units/hr, the pump must be set to 5 mL/hr, not 50 mL/hr. The described action causes a severe overdose.
3
Assess the phenytoin administration.
Unsafe practice identified.
Phenytoin is chemically incompatible with dextrose solutions and will precipitate. It must only be mixed or flushed with normal saline.
4
Evaluate the TPN substitution action.
Safe practice identified.
If TPN is abruptly stopped, substituting with D10W at the same rate prevents profound rebound hypoglycemia.
5
Determine the priority of care.
Unsafe prioritization identified.
An alarming pump for a critical vasoactive medication (nitroglycerin) takes precedence over mild peripheral site pruritus.

Key Concept

Safe parenteral therapy requires accurate dosage calculations, verification of IV fluid compatibility, proactive complication management (such as preventing hypoglycemia with TPN), and appropriate prioritization of critical medication infusions.

Question 776Question →

A client with a mechanical small bowel obstruction has been on low continuous nasogastric (NG) wall suction for the past 4848 hours. The client begins to report numbness and tingling around the mouth and muscle cramping in the calves. Morning arterial blood gas (ABG) results are: pH 7.517.51, PaCO 2_2 4343 mm Hg, HCO 3−_3^- 3232 mEq/L. To reduce the risk of a severe complication associated with these findings, which focused assessment should the nurse perform next?

Show answer & explanation

Answer: Analyze the client's electrocardiogram (ECG) rhythm strip for prominent U waves or ST depression.

Answer

Analyze the client's electrocardiogram (ECG) rhythm strip for prominent U waves or ST depression.
The correct answer addresses the most severe physiological threat stemming from the client's current status. The ABG indicates metabolic alkalosis, a direct result of gastric acid loss from NG suction. In metabolic alkalosis, potassium shifts into the cells, leading to hypokalemia. Simultaneously, calcium binds more readily to albumin, resulting in decreased ionized calcium, which causes the tetany (numbness, tingling, cramping) the client reports. The most life-threatening complication of hypokalemia is the development of cardiac dysrhythmias. The nurse must prioritize analyzing the ECG for classic signs of hypokalemia, such as prominent U waves and ST depression, to mitigate this severe risk.

Step-by-Step Solution

1
Interpret the provided arterial blood gas (ABG) values.
The pH of 7.517.51 indicates alkalosis, and the HCO 3−_3^- of 3232 mEq/L indicates a metabolic primary cause. The PaCO 2_2 is normal, indicating an uncompensated state.
Identifying the exact acid-base imbalance is the first step in anticipating the client's physiological complications.
2
Correlate the acid-base imbalance with the clinical scenario.
Prolonged nasogastric suction removes hydrochloric acid from the stomach, which is the direct cause of the metabolic alkalosis.
Understanding the etiology helps anticipate the associated secondary electrolyte shifts.
3
Identify the electrolyte derangements associated with metabolic alkalosis.
Metabolic alkalosis triggers an intracellular shift of potassium, causing hypokalemia. It also increases calcium binding to albumin, decreasing ionized calcium and causing tetany (manifested as numbness and cramping).
Electrolyte imbalances drive the most immediate and life-threatening complications.
4
Determine the highest-priority nursing assessment to reduce the risk of a severe complication.
Hypokalemia severely destabilizes cardiac conduction, risking lethal dysrhythmias. Assessing the ECG for hypokalemic indicators (U waves, ST depression) is the most critical intervention.
Cardiac dysrhythmias pose the most immediate threat to the client's life and require rapid identification.

Question 777Question →

A client with a history of recurrent seizures is admitted to the medical unit. The client has a single patent peripheral intravenous catheter with a continuous infusion of 5% dextrose in water (D5W) at 75 mL/hr. The healthcare provider prescribes an intermittent infusion of intravenous phenytoin. Which action is most appropriate for the nurse to take?

Show answer & explanation

Answer: Stop the continuous D5W infusion, flush the catheter with 0.9% sodium chloride, infuse the phenytoin, and flush again with 0.9% sodium chloride.

Answer

The correct action is to stop the continuous D5W infusion, flush the catheter with 0.9% sodium chloride, infuse the phenytoin, and flush again with 0.9% sodium chloride.
Phenytoin is highly incompatible with dextrose-containing solutions and will rapidly crystallize if they mix. Because the client only has one peripheral line, the safest approach is to stop the primary D5W infusion, flush the tubing with a compatible fluid (0.9% sodium chloride) to clear the dextrose, infuse the phenytoin, and then flush again with normal saline before resuming the D5W.

Step-by-Step Solution

1
Analyze the prescribed medication and the current continuous intravenous fluid.
The prescribed medication is phenytoin, and the running fluid is 5% dextrose in water (D5W).
Identifying the components is essential to check for drug-solution compatibility.
2
Determine the compatibility of phenytoin with D5W.
Phenytoin is highly incompatible with dextrose solutions and will form a precipitate.
Administering incompatible medications together can cause catheter occlusion and severe patient harm.
3
Select the appropriate nursing intervention for administering an incompatible medication through a single line.
The nurse must stop the primary infusion and flush the line with a compatible solution (0.9% sodium chloride) before and after administering the phenytoin.
This technique clears the tubing of the incompatible fluid, allowing safe administration without the need for a second intravenous access site.

Show answer & explanation

Answer

The correct sequence is to first stay with the client and call for help, then position the client to reduce abdominal tension, cover the exposed organs with moist sterile dressings, assess vital signs for shock, and finally prepare for emergency surgery.
Wound evisceration is a life-threatening complication that requires immediate, prioritized nursing interventions to reduce the risk of tissue necrosis and shock. The nurse must first ensure safety by calling for help while staying with the client. Next, the nurse minimizes further damage by reducing intra-abdominal tension through positioning. The exposed tissue is then protected with sterile, moist dressings. Once the immediate anatomical threat is managed, the nurse assesses the systemic response by obtaining vital signs, and finally, completes preparations for definitive surgical repair.

Step-by-Step Solution

1
Stay with the client, call for immediate assistance, and instruct a colleague to notify the surgeon.
Assistance is secured without leaving the client alone.
Evisceration is a surgical emergency. The nurse must remain with the client to prevent further injury and manage the airway and hemodynamics while delegating the notification of the healthcare provider.
2
Place the client in a low Fowler's position with the knees flexed.
Intra-abdominal pressure is decreased.
This specific position relieves tension on the abdominal wall muscles, which reduces the risk of more bowel loops protruding through the open fascia.
3
Cover the protruding bowel with sterile dressings saturated in normal saline.
The exposed bowel is protected from dehydration and infection.
Internal organs will rapidly become necrotic if allowed to dry out. Sterile saline maintains moisture, and sterile technique prevents the introduction of environmental pathogens.
4
Obtain the client's vital signs and monitor for manifestations of shock.
The client's hemodynamic status is evaluated.
The sudden exposure of internal organs and potential fluid shifts can trigger shock. Baseline vital signs are necessary to guide fluid resuscitation and inform the surgeon.
5
Prepare the client for immediate surgical intervention.
The client is readied for definitive treatment.
The only definitive treatment for an evisceration is emergency surgical repair. The nurse prepares the client by ensuring patent intravenous access and maintaining NPO status.

A nurse is caring for a client admitted with severe diabetic ketoacidosis (DKA). The client is currently receiving a continuous intravenous regular insulin infusion along with normal saline. Which assessment finding requires the most immediate intervention by the nurse?

Show answer & explanation

Answer: The sudden appearance of flattened T waves and prominent U waves on the cardiac monitor

Answer

The sudden appearance of flattened T waves and prominent U waves on the cardiac monitor.
The correct answer identifies flattened T waves and prominent U waves, which are hallmark electrocardiogram changes indicating severe hypokalemia. Continuous intravenous insulin drives both glucose and potassium into the cells, rapidly depleting serum intravascular potassium levels. Severe hypokalemia can quickly lead to lethal cardiac arrhythmias and requires immediate life-saving intervention, such as alerting the provider and preparing to administer intravenous potassium chloride.

Step-by-Step Solution

1
Analyze the physiological effects of continuous intravenous insulin therapy.
Insulin drives both serum glucose and serum potassium into the intracellular space.
Understanding the mechanism of action of the treatment helps anticipate potential iatrogenic complications.
2
Evaluate the clinical significance of the provided assessment findings.
The ABG shows expected compensation. The vital signs and abdominal pain are expected consequences of DKA. The ECG changes (flattened T wave, prominent U wave) indicate severe hypokalemia.
Differentiating between expected disease manifestations and acute, life-threatening complications is required for safe care.
3
Prioritize interventions based on immediate life threats.
Severe hypokalemia can rapidly progress to lethal cardiac arrhythmias (such as ventricular fibrillation), making it the highest priority for intervention.
According to the ABCs (Airway, Breathing, Circulation) and acute survival potential, preventing cardiac arrest supersedes managing expected symptoms.

A nurse is preparing to remove a non-tunneled central venous catheter (CVC) from a client's internal jugular vein. Place the following nursing actions in the correct chronological order to ensure client safety and prevent complications during the procedure.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence for removing a central venous catheter is to position the client supine, remove the dressing, instruct the client to bear down, withdraw the catheter, apply firm pressure, and finally inspect the catheter tip.
The safe removal of a central venous catheter prioritizes the prevention of an air embolism. The procedure begins by placing the client flat or in a slight Trendelenburg position to increase central venous pressure. After removing the dressing to free the catheter, the nurse instructs the client to bear down (Valsalva maneuver) to elevate intrathoracic pressure. The catheter is withdrawn exactly during this maneuver to ensure the vein remains under positive pressure. Immediate manual pressure is then applied to the site to achieve hemostasis and form an airtight seal over the tract. Finally, the nurse inspects the catheter tip to ensure no fragments were retained in the patient.

Step-by-Step Solution

1
Place the client in a supine or slight Trendelenburg position.
Central venous pressure is increased.
This positioning prevents an air embolism by keeping the venous pressure higher than atmospheric pressure.
2
Remove the transparent dressing and any securement devices.
The catheter is freed from the skin.
The site must be fully prepared before the client is instructed to alter their breathing pattern.
3
Instruct the client to take a deep breath and bear down.
Intrathoracic pressure is temporarily increased.
The Valsalva maneuver ensures positive pressure in the vein, further protecting against air entry.
4
Withdraw the catheter smoothly and continuously.
The catheter is completely removed from the jugular vein.
Removing the line while the client bears down minimizes the time the open tract is exposed to potential air intake.
5
Apply immediate, firm pressure to the insertion site using sterile gauze.
Hemostasis is achieved and the entry tract is sealed.
Firm pressure prevents bleeding and physically blocks air from entering the vein.
6
Inspect the distal tip of the removed catheter.
The physical integrity of the catheter is confirmed.
This verification ensures no pieces of the catheter have broken off into the client's bloodstream.

Key Concept

Safe removal of a central venous catheter requires strict adherence to procedural steps that prevent air embolism, primarily through patient positioning and the utilization of the Valsalva maneuver.
