Correct Answer: B

Rationale: The correct action for the nurse to take is to administer sodium polystyrene sulfonate. This medication promotes potassium excretion and helps lower serum potassium levels in clients with hyperkalemia, which is indicated by a high potassium level. Sodium bicarbonate (choice A) is not used to treat hyperkalemia. Calcium gluconate (choice C) and calcium carbonate (choice D) are used to manage hyperkalemia by stabilizing cell membranes but are not the initial treatment choice for lowering potassium levels.

Correct Answer: D

Rationale: The correct answer is D, dark-colored urine. Dark-colored urine can indicate various issues such as dehydration, liver problems, or blood in the urine, which could be concerning and require further evaluation by the provider. Choices A, B, and C are not necessarily findings that would need immediate reporting to the provider. A urine output of 50 mL in 2 hours might be low but could be influenced by various factors and might not always require immediate action. The presence of an indwelling urinary catheter is a known history and not a new finding. Frequent urination at night could be a symptom related to various conditions but may not be an urgent concern unless accompanied by other significant symptoms.

Correct Answer: C

Rationale: The correct action for the nurse to take is to limit IV exposure to light. Nitroprusside is light-sensitive, and exposure to light can lead to its degradation, potentially reducing its efficacy in treating severe hypertension. Keeping calcium gluconate at the bedside (Choice A) is not directly related to managing nitroprusside infusion. While monitoring blood pressure every 2 hours (Choice B) is important in managing hypertension, it is not the immediate action required to ensure medication efficacy. Attaching an inline filter to the IV tubing (Choice D) may help filter particles but does not address the critical concern of light sensitivity associated with nitroprusside administration.

Correct Answer: B

Rationale: The correct statement the nurse should include when teaching a client taking clopidogrel is to monitor for signs of infection. Clopidogrel affects platelet levels and can increase the risk of bleeding. Monitoring for signs of infection is crucial because a compromised immune system can make the client more susceptible to infections. Choices A, C, and D are incorrect because clopidogrel is not directly linked to alcohol restrictions, food requirements, or specific water intake instructions.

Correct Answer: B

Rationale: The correct answer is B. Limiting potassium-rich foods is crucial for clients with chronic kidney disease to prevent hyperkalemia, a common complication. Increasing intake of potassium-rich foods like bananas (choice A), protein-rich foods (choice C), or dairy products (choice D) can exacerbate hyperkalemia in these clients. Bananas, protein-rich foods, and dairy products are all high in potassium, which is detrimental for individuals with chronic kidney disease. Therefore, choices A, C, and D are incorrect.
