Correct Answer: B

Rationale: Pruritus is a common symptom in clients with cirrhosis due to bile salts accumulating in the skin. Applying lotion to the skin helps soothe the itching and can prevent skin breakdown. Acetaminophen can worsen liver damage in clients with cirrhosis as it is metabolized in the liver. Encouraging a high-protein diet is not directly related to relieving pruritus. Providing a warm bath may further dry the skin, exacerbating the itching. Therefore, the most appropriate intervention to help relieve pruritus in a client with cirrhosis is to apply lotion to the skin.

Correct Answer: B

Rationale: The correct answer is B: Lowered cholesterol levels. Atorvastatin is a medication commonly prescribed to lower cholesterol levels, which is crucial in reducing the risk of further cardiovascular events, including myocardial infarction (MI). Monitoring cholesterol levels is essential to assess the effectiveness of atorvastatin therapy and its role in preventing future cardiac complications. Choices A, C, and D are incorrect because increased blood pressure, decreased heart rate, and improved liver function are not direct indicators of atorvastatin's effectiveness in a client with a history of MI.

Correct Answer: C

Rationale: Regular monitoring of blood pressure is crucial for individuals with hypertension to assess the effectiveness of the prescribed medication and to ensure blood pressure is within the target range. This helps in managing hypertension and preventing complications associated with high blood pressure. Choices A, B, and D are incorrect because while taking the medication in the morning may be recommended for some drugs, it is not the key instruction for hydrochlorothiazide. Avoiding foods high in potassium and decreasing high-sodium foods are important dietary considerations for certain conditions, but they are not the immediate focus when starting hydrochlorothiazide.

Correct Answer: C

Rationale: Fludrocortisone, such as Florinef, is a mineralocorticoid that promotes sodium retention and potassium excretion, which can lead to hypernatremia. Therefore, the nurse should closely monitor for hypernatremia when a client with Addison's disease is being treated with fludrocortisone. Hyperkalemia (Choice A) is incorrect because fludrocortisone promotes potassium excretion, leading to hypokalemia rather than hyperkalemia. Hyponatremia (Choice B) is incorrect as fludrocortisone promotes sodium retention. Hypocalcemia (Choice D) is unrelated to the action of fludrocortisone.

Correct Answer: C

Rationale: The correct instruction for a client prescribed levothyroxine (Synthroid) is to take the medication on an empty stomach. This ensures optimal absorption of levothyroxine. Taking it with a meal can interfere with absorption due to food interactions. Taking it at bedtime may lead to inconsistent absorption as it should be taken at the same time every day in the morning. Taking it with an antacid can reduce the absorption of levothyroxine, making it less effective.
