Nursing Elites

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. What is the priority nursing intervention for a patient experiencing a myocardial infarction?

• A. Administer aspirin
• B. Administer nitroglycerin
• C. Administer morphine
• D. Prepare for surgery

Correct answer: A

Rationale: The correct answer is to administer aspirin. Administering aspirin is a priority nursing intervention for a patient experiencing a myocardial infarction because it helps reduce the risk of further clot formation. Aspirin is a common medication given during the early stages of a heart attack to prevent additional clotting. Administering nitroglycerin may also be indicated to help relieve chest pain by dilating blood vessels, but aspirin takes precedence due to its role in preventing clot progression. Administering morphine is not typically the first intervention in myocardial infarction as it can mask symptoms and delay other critical treatments. Surgery is not an immediate priority in the initial management of a myocardial infarction.

3. 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.

4. A client with diabetes mellitus is experiencing hypoglycemia. Which of the following findings should the nurse expect?

• A. Polyuria
• B. Warm, dry skin
• C. Irritability
• D. Hyperventilation

Correct answer: C

Rationale: Irritability is a common finding in clients with hypoglycemia due to decreased glucose levels in the brain. Polyuria (excessive urination) is not typically associated with hypoglycemia, but rather with hyperglycemia. Warm, dry skin is not a typical finding in hypoglycemia; instead, the skin may be cool and clammy. Hyperventilation is not a common finding in hypoglycemia; instead, shallow breathing or difficulty breathing may occur.

5. A nurse is providing discharge teaching to a client who has a new prescription for warfarin. Which of the following client statements indicates an understanding of the teaching?

• A. I will need to have my INR checked regularly while taking this medication.
• B. I should avoid eating leafy green vegetables while taking this medication.
• C. I will stop taking this medication if I experience nausea.
• D. I will avoid taking aspirin while taking this medication.

Correct answer: A

Rationale: The correct answer is A because clients taking warfarin should have their INR (International Normalized Ratio) checked regularly to monitor the medication's effectiveness and adjust the dose if needed. This monitoring helps to ensure the medication is working correctly and the client is within the therapeutic range. Choice B is incorrect because clients on warfarin should not avoid leafy green vegetables but should maintain a consistent intake. Leafy green vegetables contain vitamin K, which can affect warfarin, so it's important to maintain a consistent intake to keep INR stable. Choice C is incorrect as clients should not stop taking warfarin abruptly without consulting their healthcare provider as it can lead to serious health risks like blood clots. Choice D is incorrect because while taking warfarin, it is important to avoid unnecessary aspirin use due to an increased risk of bleeding. However, this statement does not indicate an understanding of the teaching about the need for regular INR monitoring.
