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.

Correct Answer: B

Rationale: The correct answer is B: Hypotension. Metoprolol, a beta-blocker, can lead to a decrease in blood pressure, resulting in hypotension. Monitoring blood pressure regularly is essential to detect and manage this adverse effect. Choices A, C, and D are incorrect because metoprolol typically does not cause bradycardia, tachycardia, or hyperglycemia as its primary adverse effects.

Correct Answer: B

Rationale: The correct answer is B: 'Monitor for constipation.' Calcium carbonate can cause constipation as a side effect. Educating clients on dietary adjustments, such as increasing fluid intake and fiber consumption, can help alleviate this issue. Choice A is incorrect because calcium carbonate supplementation is used to treat hypocalcemia, not cause it. Choice C is incorrect because calcium carbonate should be taken with food for optimal absorption. Choice D is incorrect because calcium carbonate is available over the counter, not as a prescription medication.

Correct Answer: C

Rationale: Correct. Trazodone is an antidepressant that can impact mood and behavior. Monitoring for changes in mood or behavior is crucial to assess the effectiveness and potential side effects of the medication. Monitoring blood glucose levels is not typically associated with trazodone use. While trazodone can affect liver function in some cases, monitoring liver function is not the primary concern compared to assessing mood changes. Trazodone can cause changes in heart rate in some patients, but the priority monitoring in this case should be related to its effects on mood.

Correct Answer: B

Rationale: The correct answer is B: Respiratory status. When caring for a client with asthma, it is essential to monitor their respiratory status to detect any changes in breathing or signs of airway obstruction. Monitoring heart rate (choice A) may be important in some situations but is not the priority when managing asthma. Blood glucose levels (choice C) and liver function (choice D) are not directly related to asthma and would not be the primary focus of monitoring for a client with this condition.
