1. Which lab value should be closely monitored for a patient receiving heparin therapy?

• A. Monitor aPTT
• B. Monitor INR
• C. Monitor potassium levels
• D. Monitor sodium levels

Correct answer: A

Rationale: The correct answer is to monitor aPTT. Activated Partial Thromboplastin Time (aPTT) is crucial to monitor when a patient is receiving heparin therapy. Heparin works by potentiating antithrombin III, leading to the inhibition of thrombin and factor Xa. Monitoring aPTT helps ensure the patient is within the therapeutic range for heparin, reducing the risk of bleeding complications. Monitoring INR (Choice B) is more relevant for patients on warfarin therapy. Monitoring potassium (Choice C) and sodium levels (Choice D) is important but not specific to heparin therapy.

2. 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.

3. What is the most important assessment for a patient post-surgery?

• A. Monitor vital signs
• B. Check surgical site for bleeding
• C. Check for abnormal breath sounds
• D. Check skin color

Correct answer: A

Rationale: The correct answer is to monitor vital signs post-surgery. Vital signs provide crucial information about a patient's physiological status, helping detect early signs of complications such as shock, bleeding, or infection. Checking the surgical site for bleeding is important but falls secondary to monitoring vital signs, which give a broader overview of the patient's condition. Checking for abnormal breath sounds and skin color are also important assessments, but they are not as immediate and general as monitoring vital signs in detecting various post-surgical complications.

4. A healthcare professional is preparing to administer enoxaparin to a client. Which of the following actions should the healthcare professional take?

• A. Administer the medication intramuscularly.
• B. Inject the medication into the lateral abdominal wall.
• C. Massage the injection site after administration.
• D. Discard the prefilled syringe after expelling the air bubble.

Correct answer: B

Rationale: The correct answer is to inject the medication into the lateral abdominal wall when administering enoxaparin. This is the recommended technique to ensure proper absorption and prevent tissue damage. Choice A is incorrect because enoxaparin should be administered subcutaneously, not intramuscularly. Choice C is incorrect as massaging the injection site after administration is not recommended, as it can cause bruising and discomfort. Choice D is incorrect because the prefilled syringe should not be discarded after expelling the air bubble; it should be used for the injection.

5. A nurse is caring for a client who has pneumonia. Which of the following findings should the nurse identify as an indication of the effectiveness of the treatment?

• A. Respiratory rate of 24/min
• B. White blood cell count of 15,000/mm3
• C. SpO2 of 95%
• D. Clear breath sounds

Correct answer: D

Rationale: Clear breath sounds are an essential indicator of effective pneumonia treatment as they suggest resolution of the lung infection. A normal respiratory rate (A) indicates adequate breathing but does not directly reflect the effectiveness of pneumonia treatment. An elevated white blood cell count (B) is a sign of infection and may not decrease immediately with treatment. While maintaining an SpO2 of 95% (C) is crucial for oxygenation, it may not directly indicate the effectiveness of pneumonia treatment.
