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 healthcare provider is providing dietary teaching to a client who has osteoporosis. Which of the following foods should the healthcare provider recommend as the best source of calcium?

• A. Broccoli
• B. Cheddar cheese
• C. Almonds
• D. Fortified orange juice

Correct answer: B

Rationale: Cheddar cheese is a rich source of calcium and should be recommended to clients with osteoporosis. While broccoli and almonds also contain calcium, cheddar cheese provides a higher amount per serving. Fortified orange juice may contain added calcium, but it is not as concentrated a source as cheddar cheese. Therefore, the best choice for a client with osteoporosis seeking a high calcium food is cheddar cheese.

3. A nurse is providing teaching to a client who has type 1 diabetes mellitus about foot care. Which of the following instructions should the nurse include?

• A. Soak your feet in warm water daily.
• B. Wear cotton socks.
• C. Trim your toenails straight across.
• D. Apply lotion to your feet after bathing.

Correct answer: C

Rationale: The correct answer is C: 'Trim your toenails straight across.' Trimming toenails straight across helps prevent ingrown toenails, which is important for clients with diabetes to prevent infections. Choice A is incorrect because soaking feet in warm water can lead to skin breakdown and infections. Choice B is incorrect as cotton socks can retain moisture, increasing the risk of fungal infections. Choice D is also incorrect as applying lotion between the toes can create a moist environment, increasing the risk of infections.

4. A nurse is assessing a client who is receiving furosemide for heart failure. Which of the following findings is the priority to report to the provider?

• A. Blood pressure of 98/58 mm Hg
• B. Urine output of 50 mL/hr
• C. Serum potassium level of 3.2 mEq/L
• D. Weight loss of 0.5 kg (1.1 lb) in 24 hours

Correct answer: C

Rationale: The correct answer is C. A serum potassium level of 3.2 mEq/L indicates hypokalemia, a potential complication of furosemide therapy, and should be reported immediately. Hypokalemia can lead to serious cardiac dysrhythmias. Choices A, B, and D are important assessments but are not as critical as managing serum potassium levels in a client receiving furosemide for heart failure.

5. A client is starting therapy with a statin medication. Which of the following instructions should the nurse include?

• A. Take the medication on an empty stomach.
• B. Avoid consuming grapefruit juice.
• C. Increase intake of dietary fiber.
• D. Take the medication in the morning.

Correct answer: B

Rationale: The correct instruction the nurse should include is to advise the client to avoid consuming grapefruit juice when taking statin medication. Grapefruit juice can interfere with the metabolism of statins, leading to an increased risk of adverse effects. Taking the medication on an empty stomach (Choice A) or in the morning (Choice D) is not specifically necessary for statins. While increasing dietary fiber intake (Choice C) is generally beneficial for health, it is not a specific instruction related to taking statin medication.
