A nurse is caring for a client with a new prescription for atorvastatin. Which of the following should the nurse monitor?

Correct Answer: A

Rationale: The correct answer is A: Liver function tests. Atorvastatin, a medication commonly used to lower cholesterol levels, can potentially cause liver damage as a side effect. Monitoring liver function tests is essential to detect any abnormalities early. Choices B, C, and D are incorrect because atorvastatin is not known to directly impact potassium levels, blood glucose levels, or serum calcium levels. While these parameters may be monitored for other reasons, the priority when administering atorvastatin is to monitor liver function due to the risk of hepatotoxicity.

Correct Answer: A

Rationale: Corrected Rationale: Decreased urine output can indicate renal complications or dehydration, which are common post-surgical complications. Monitoring urine output is crucial for detecting early signs of kidney dysfunction or fluid imbalances. Increased appetite, improved mobility, and normal temperature are not typical signs of immediate post-surgical complications and would not be the priority for monitoring in this case.

Correct Answer: B

Rationale: The correct answer is B. Prednisone can cause weight gain and other side effects, so clients should be informed about these potential risks. Choice A is incorrect because prednisone should not be stopped abruptly to prevent withdrawal symptoms. Choice C is incorrect because prednisone can have various side effects. Choice D is incorrect because prednisone is usually prescribed with specific dosing instructions and should not be taken irregularly or only when symptoms occur.

Correct Answer: B

Rationale: The correct answer is B: Peripheral edema. Peripheral edema, the accumulation of fluid causing swelling in the extremities, is a classic sign of heart failure due to fluid overload. This occurs because the heart's reduced pumping efficiency leads to fluid backup in the circulatory system. Choices A, C, and D are incorrect. Decreased heart rate is not typically associated with heart failure; instead, tachycardia or an increased heart rate may be observed. Increased energy levels are not an expected finding in heart failure, as this condition often causes fatigue and weakness. Hyperglycemia is not a direct sign of heart failure; however, it can be present in individuals with uncontrolled diabetes or as a result of certain treatments, but it is not a specific indicator of heart failure.

Correct Answer: A

Rationale: Corrected Rationale: Metoprolol is a beta-blocker commonly used to treat conditions like hypertension and angina. As a beta-blocker, it primarily affects the cardiovascular system by reducing heart rate and blood pressure. Therefore, the nurse should monitor the client's blood pressure regularly to assess the drug's effectiveness and ensure that it is within the therapeutic range. Monitoring liver function, serum potassium levels, or blood glucose is not typically required for clients taking metoprolol, as its primary impact is on the heart and blood vessels, making choice A the most appropriate monitoring parameter.
