Correct Answer: A

Rationale: The correct answer is A because limiting high-sodium foods is essential in managing hypertension and preventing complications. High sodium intake can lead to increased blood pressure levels. Choice B is important too, but solely relying on medications without lifestyle modifications may not be as effective in controlling hypertension. Choice C is also crucial for monitoring progress, but without dietary changes, blood pressure control may be challenging. Choice D, limiting high-fat foods, is beneficial for overall health but is not as directly related to managing hypertension as limiting high-sodium foods.

Correct Answer: B

Rationale: The correct answer is B: Potassium. Spironolactone is a potassium-sparing diuretic, which means it helps retain potassium while eliminating sodium. This is beneficial for patients with cirrhosis and ascites as they are at risk of low potassium levels. Choice A, Sodium, is incorrect as Spironolactone does not spare the elimination of sodium but rather helps eliminate it. Choice C, Phosphate, is incorrect as Spironolactone does not directly affect phosphate levels. Choice D, Albumin, is incorrect as Spironolactone does not spare the elimination of albumin.

Correct Answer: B

Rationale: Checking the client's gag reflex is the appropriate action in this scenario. It helps assess the client's ability to swallow safely without the risk of aspiration. Adding a thickening agent to the fluids (Choice A) may be considered later if swallowing difficulties persist. Feeding the client only solid foods (Choice C) can increase the risk of aspiration in this case, and increasing the rate of intravenous fluids (Choice D) does not address the swallowing concern.

Correct Answer: C

Rationale: In a client with COPD, it is crucial to prevent carbon dioxide retention by avoiding high oxygen levels. As the client's oxygen is running at 6 liters per minute and he is showing signs of oxygen toxicity, such as flushed color and low respirations, the nurse's priority should be to lower the oxygen rate. This action helps prevent worsening the client's condition. Obtaining an EKG, placing the client in high Fowler's position, or taking baseline vital signs are important assessments but addressing the potential oxygen toxicity takes precedence in this scenario.

Correct Answer: D

Rationale: Choice D is the correct answer because stopping medications when feeling better can be harmful in heart failure. It is essential to complete the full course of medication as prescribed by the healthcare provider to effectively manage heart failure. Choices A, B, and C demonstrate good understanding and compliance with heart failure management strategies, such as monitoring weight, restricting sodium intake, and adhering to prescribed medications, respectively.
