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. Which of the following is the most concerning electrolyte imbalance for a patient on furosemide?

• A. Hypokalemia
• B. Hyperkalemia
• C. Hyponatremia
• D. Hypercalcemia

Correct answer: A

Rationale: The correct answer is Hypokalemia. Furosemide, a loop diuretic, can lead to potassium depletion in the body, causing hypokalemia. This is a significant concern as low potassium levels can result in cardiac arrhythmias and other serious complications. Hyperkalemia (Choice B) is unlikely to occur as a result of furosemide use. Hyponatremia (Choice C) is more commonly associated with thiazide diuretics. Hypercalcemia (Choice D) is not typically linked to furosemide use.

3. A client has a new prescription for furosemide. Which of the following instructions should the nurse include?

• A. Avoid consuming dairy products.
• B. Increase your intake of potassium-rich foods.
• C. Limit fluid intake to prevent dehydration.
• D. Take the medication at bedtime.

Correct answer: B

Rationale: The correct answer is to instruct the client to increase their intake of potassium-rich foods when taking furosemide. Furosemide is a loop diuretic that can cause potassium loss, so consuming potassium-rich foods like bananas and oranges can help maintain adequate potassium levels. Choice A is incorrect because there is no need to avoid consuming dairy products. Choice C is incorrect because while fluid intake may need to be monitored, the general instruction is not to limit fluids to prevent dehydration. Choice D is incorrect because furosemide is usually best taken during the day to avoid disrupting sleep with frequent urination.

4. A nurse is caring for a client who is receiving continuous enteral nutrition through a nasogastric tube. Which of the following actions should the nurse take?

• A. Administer the feeding using a large-bore syringe
• B. Check the placement of the tube every 8 hours
• C. Flush the tube with 5 mL of water every 6 hours
• D. Maintain the client in an upright position

Correct answer: B

Rationale: The correct action for the nurse to take is to check the placement of the nasogastric tube every 8 hours. This is crucial to ensure that the tube is correctly positioned in the stomach, reducing the risk of complications such as aspiration. Administering the feeding using a large-bore syringe (Choice A) is not recommended for enteral nutrition. Flushing the tube with water every 6 hours (Choice C) is not necessary for continuous enteral nutrition. Maintaining the client in an upright position (Choice D) is generally preferred to reduce the risk of aspiration, but it is not the most critical action compared to verifying tube placement.

5. Which lab value is most critical to monitor in a patient receiving insulin therapy?

• A. Monitor blood glucose
• B. Monitor potassium levels
• C. Monitor calcium levels
• D. Monitor sodium levels

Correct answer: A

Rationale: The correct answer is to monitor blood glucose levels. When a patient is receiving insulin therapy, it is crucial to monitor blood glucose levels regularly to prevent hypoglycemia, a potential side effect of insulin therapy. Monitoring potassium, calcium, or sodium levels is important for different medical conditions or treatments and is not directly related to insulin therapy.
