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. A nurse is caring for a client who has a new prescription for spironolactone. Which of the following laboratory values should the nurse monitor to evaluate the effectiveness of the medication?

• A. Serum sodium.
• B. Serum calcium.
• C. Serum potassium.
• D. Serum glucose.

Correct answer: C

Rationale: Corrected Rationale: Spironolactone is a potassium-sparing diuretic, so serum potassium should be monitored to evaluate its effectiveness. Monitoring serum potassium levels is crucial because spironolactone can cause hyperkalemia as a side effect. Serum sodium, serum calcium, and serum glucose levels are not directly affected by spironolactone and would not provide an accurate assessment of the medication's effectiveness.

3. A client with lactose intolerance and has eliminated dairy products from his diet should increase consumption of which of the following foods?

• A. Spinach
• B. Peanut butter
• C. Ground beef
• D. Carrots

Correct answer: A

Rationale: Spinach is the correct answer because it is a good source of calcium. Since the client has eliminated dairy products due to lactose intolerance, which are a common source of calcium, increasing spinach consumption can help compensate for the lost calcium. Peanut butter, ground beef, and carrots are not significant sources of calcium and therefore not the best choice for this client.

4. When discussing clients designating a health care proxy in situations requiring a durable power of attorney for health care (DPAHC), what information should the charge nurse include?

• A. The proxy should make health care decisions for the client regardless of the client's ability to do so.
• B. The proxy can make financial decisions if the need arises.
• C. The proxy can make treatment decisions if the client is under anesthesia.
• D. The proxy should manage legal issues for the client.

Correct answer: C

Rationale: The correct answer is C. The charge nurse should include information that the proxy can make treatment decisions if the client is under anesthesia. This is a key function of a durable power of attorney for health care. Choices A, B, and D are incorrect because a health care proxy's role is specifically related to making health care decisions, not financial decisions, legal issues, or decisions made under anesthesia.

5. A nurse is teaching a prenatal class about infections. Which statement by a participant indicates a need for further teaching?

• A. I can clean the cat's litter box during pregnancy.
• B. I can visit someone with the flu after receiving the vaccine.
• C. I should take antibiotics for viral infections.
• D. I should wash my hands after gardening.

Correct answer: C

Rationale: The correct answer is C. This statement indicates a need for further teaching because antibiotics are ineffective against viral infections. It is important to educate the participant that antibiotics are only effective against bacterial infections, not viral ones. Choices A, B, and D are correct statements that promote good hygiene practices and infection prevention during pregnancy.
