Nursing Elites

1. A client with acute kidney injury (AKI) is experiencing hyperkalemia. What intervention should the nurse prioritize?

• A. Administer IV calcium gluconate.
• B. Administer sodium polystyrene sulfonate (Kayexalate).
• C. Administer insulin with dextrose.
• D. Restrict potassium intake in the client's diet.

Correct answer: A

Rationale: The correct intervention for a client with acute kidney injury (AKI) experiencing hyperkalemia is to administer IV calcium gluconate. Calcium gluconate helps stabilize the myocardium and prevent life-threatening arrhythmias in hyperkalemia by antagonizing the cardiac effects of high potassium levels. Choice B, administering sodium polystyrene sulfonate (Kayexalate), is used to lower potassium levels in the gastrointestinal tract but is not the priority in acute severe hyperkalemia. Choice C, administering insulin with dextrose, helps drive potassium into cells but is not the priority in a client at risk for arrhythmias due to hyperkalemia. Choice D, restricting potassium intake in the client's diet, is a long-term strategy but is not the immediate priority in managing acute hyperkalemia.

2. A client with hypertension is prescribed a thiazide diuretic. What dietary recommendation should the nurse make?

• A. Encourage a diet low in carbohydrates and fats.
• B. Avoid foods high in vitamin K, such as spinach and kale.
• C. Increase salt intake to prevent dehydration.
• D. Eat potassium-rich foods like bananas and oranges.

Correct answer: D

Rationale: The correct answer is D: 'Eat potassium-rich foods like bananas and oranges.' Thiazide diuretics can lead to potassium loss, so it is essential for clients to consume potassium-rich foods to maintain adequate levels. Choice A is incorrect because focusing solely on low carbohydrates and fats does not address the specific issue of potassium loss. Choice B is unrelated as vitamin K content is not a concern with thiazide diuretics. Choice C is incorrect as increasing salt intake would exacerbate hypertension and not prevent dehydration.

3. The nurse is planning to administer two medications at 0900. Which property of the drugs indicates a need to monitor the client for toxicity?

• A. Short half-life
• B. High therapeutic index
• C. Highly protein-bound
• D. Low bioavailability

Correct answer: C

Rationale: The correct answer is C, 'Highly protein-bound.' Drugs that are highly protein-bound can displace from protein-binding sites, leading to increased free drug levels in the blood, which can result in toxicity. Monitoring the client for toxicity is crucial when administering highly protein-bound drugs. Choices A, B, and D are incorrect. A short half-life does not necessarily indicate a need for monitoring toxicity; a high therapeutic index indicates a wide safety margin between the effective dose and the toxic dose, reducing the risk of toxicity; low bioavailability refers to the fraction of the drug that reaches the systemic circulation unchanged and does not directly relate to the risk of toxicity.

4. A 5-week-old infant who developed projectile vomiting over the last two weeks is diagnosed with hypertrophic pyloric stenosis. Which intervention should the nurse plan to implement?

• A. Instruct the mother to give the child sugar water only.
• B. Offer oral rehydration solution every 2 hours.
• C. Provide Pedialyte feedings via nasogastric tube.
• D. Maintain intravenous fluid therapy per prescription.

Correct answer: D

Rationale: The correct intervention for a 5-week-old infant diagnosed with hypertrophic pyloric stenosis and experiencing projectile vomiting is to maintain intravenous fluid therapy. Intravenous fluids are crucial for rehydrating an infant suffering from dehydration due to rapid fluid loss from vomiting. Instructing the mother to provide sugar water only (choice A) is inappropriate and insufficient for rehydration. Offering oral rehydration solution every 2 hours (choice B) may not be effective if the infant continues to vomit. Providing Pedialyte feedings via nasogastric tube (choice C) may also not be as effective as intravenous fluid therapy in rapidly replenishing fluids and stabilizing the child's condition.

5. A client receiving radiation therapy for breast cancer reports dry, peeling skin at the treatment site. What action should the nurse recommend?

• A. Apply lotion to the treatment area.
• B. Use mild soap and water to cleanse the area.
• C. Cover the area with a sterile dressing.
• D. Allow the skin to air dry after washing.

Correct answer: B

Rationale: The correct recommendation for a client with dry, peeling skin at a radiation therapy treatment site is to use mild soap and water to cleanse the area. This approach helps in preventing skin irritation and reduces the risk of infection. Applying lotion (Choice A) may further irritate the skin due to the chemicals present in the lotion. Covering the area with a sterile dressing (Choice C) is not necessary unless there is an open wound that needs protection. Allowing the skin to air dry after washing (Choice D) may lead to further dryness and peeling.
