1. A client has a central venous catheter. Which of the following actions should be taken to prevent an air embolism?

A. Keep the catheter clamped when not in use
B. Have the client perform the Valsalva maneuver while the catheter is removed
C. Use a non-coring needle to access the catheter
D. Flush the catheter with 0.9% sodium chloride every 24 hours

Correct answer: B

Rationale: The correct action to prevent an air embolism in a client with a central venous catheter is to have the client perform the Valsalva maneuver while the catheter is removed. This maneuver helps to close the airway and prevent air from entering the bloodstream. Keeping the catheter clamped at all times (Choice A) is not necessary and may lead to clot formation. Using a non-coring needle (Choice C) is important for accessing the catheter but does not specifically prevent air embolism. Flushing the catheter with 0.9% sodium chloride (Choice D) helps maintain patency but does not directly prevent air embolism.

2. A nurse is planning care for a client who has pneumonia. Which of the following interventions should the nurse include to promote airway clearance?

A. Encourage the client to increase fluid intake.
B. Suction the client every 2 hours.
C. Perform chest physiotherapy every 8 hours.
D. Administer oxygen via nasal cannula.

Correct answer: A

Rationale: Encouraging the client to increase fluid intake is essential to promote airway clearance in pneumonia. Adequate hydration helps to thin respiratory secretions, making them easier to expectorate. Suctioning every 2 hours may be too frequent and can lead to airway trauma and irritation. Chest physiotherapy is not typically indicated for pneumonia unless there are specific complications. Administering oxygen via nasal cannula may be necessary to maintain oxygen saturation but does not directly promote airway clearance.

3. What is the best initial action when a patient presents with confusion?

A. Administer IV fluids
B. Perform a neurological assessment
C. Administer electrolytes
D. Prepare for a CT scan

Correct answer: B

Rationale: When a patient presents with confusion, the best initial action is to perform a neurological assessment. This assessment helps in identifying potential causes of confusion such as neurological issues, infections, metabolic abnormalities, or medication side effects. Administering IV fluids (Choice A) may be necessary based on assessment findings, but it is not the first step. Administering electrolytes (Choice C) would also depend on the assessment results. Preparing for a CT scan (Choice D) may be indicated later in the diagnostic process but is not the initial action when a patient presents with confusion.

4. Which lab value should be monitored for a patient on warfarin therapy?

A. Monitor INR
B. Monitor potassium levels
C. Monitor platelet count
D. Monitor sodium levels

Correct answer: A

Rationale: The correct answer is to monitor INR for a patient on warfarin therapy. INR monitoring is crucial as it helps assess the therapeutic effectiveness and safety of warfarin. INR stands for International Normalized Ratio, and it measures the blood's ability to clot. Monitoring potassium levels (Choice B) is not specific to warfarin therapy. Monitoring platelet count (Choice C) is important but not the primary lab value for assessing warfarin therapy. Monitoring sodium levels (Choice D) is not directly related to warfarin therapy.

5. A nurse is caring for a client who has heart failure and a prescription for digoxin. Which of the following findings should the nurse report to the provider?

A. Heart rate of 60/min
B. Respiratory rate of 16/min
C. Sodium level of 138 mEq/L
D. Weight gain of 1.5 kg (3.3 lb) in 24 hours

Correct answer: D

Rationale: The correct answer is D. A weight gain of 1.5 kg (3.3 lb) in 24 hours can indicate fluid retention and worsening heart failure in clients taking digoxin. This rapid weight gain could be due to fluid accumulation, a common sign of heart failure exacerbation. Reporting this finding to the provider is crucial for prompt intervention. Choices A, B, and C are within normal ranges and not directly indicative of worsening heart failure in this context, making them less urgent to report compared to the significant weight gain.
