Nursing Elites

1. A nurse is caring for a client who has chronic kidney disease and a serum potassium level of 6.0 mEq/L. Which of the following findings should the nurse expect?

• A. Hypokalemia
• B. Hypocalcemia
• C. Hypoglycemia
• D. Hyperkalemia

Correct answer: D

Rationale: The correct answer is D: Hyperkalemia. In chronic kidney disease, there is decreased renal excretion of potassium, leading to elevated serum potassium levels. Hypokalemia (Choice A) is low potassium levels, which is the opposite finding in this scenario. Hypocalcemia (Choice B) is decreased calcium levels and is not directly related to chronic kidney disease or elevated potassium levels. Hypoglycemia (Choice C) is low blood sugar levels and is not typically associated with chronic kidney disease or high potassium levels.

2. Which electrolyte imbalance is commonly seen in patients taking furosemide?

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

Correct answer: A

Rationale: The correct answer is A: Hypokalemia. Furosemide, a loop diuretic, can lead to potassium loss in the urine, resulting in hypokalemia. This electrolyte imbalance is commonly seen in patients taking furosemide and requires close monitoring. Choices B, C, and D are incorrect because furosemide does not typically cause hyponatremia, hyperkalemia, or hypercalcemia as frequently as it causes hypokalemia.

3. 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.

4. A client who has a positive stool culture for Clostridium difficile should be placed in which type of room for infection control purposes?

• A. Wear a face shield prior to entering the room.
• B. Place the client in a private room.
• C. Place the client in a negative pressure room.
• D. Use an alcohol-based hand rub following client care.

Correct answer: B

Rationale: Placing the client in a private room is the appropriate infection control measure for C. difficile to prevent the spread of infection. While wearing a face shield may be necessary for procedures that generate splashes or sprays, it is not the primary precaution for C. difficile. Negative pressure rooms are typically used for airborne infections, not for C. difficile. Using an alcohol-based hand rub is important for hand hygiene but is not specific to managing C. difficile infection.

5. What is the recommended dietary restriction for a patient with chronic kidney disease?

• A. Limit potassium intake
• B. Limit fluid intake
• C. Increase protein intake
• D. Increase carbohydrate intake

Correct answer: B

Rationale: The correct answer is to limit fluid intake for a patient with chronic kidney disease. This restriction helps manage fluid balance to prevent fluid overload. Choices A, C, and D are incorrect. Limiting potassium intake is essential for some patients with kidney disease, but it is not the primary dietary restriction. Increasing protein intake is usually not recommended due to the impaired kidney function in these patients. Increasing carbohydrate intake is also not a standard recommendation for patients with chronic kidney disease.
