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: A

Rationale: The correct answer is A: 'Avoid alcohol while taking this medication.' Metronidazole can cause a disulfiram-like reaction with alcohol, leading to symptoms like nausea, vomiting, flushing, and headache. Therefore, clients should be instructed to avoid alcohol consumption. Choice B is incorrect because metronidazole is not considered safe during pregnancy, especially in the first trimester. Choice C is incorrect as metronidazole is not known to cause increased appetite. Choice D is also incorrect as hair loss is not a common side effect of metronidazole.

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 to assess the patient's heart rate. Levothyroxine is a thyroid hormone replacement medication that can increase metabolism. One of the potential side effects of levothyroxine is tachycardia (rapid heart rate). Therefore, it is essential for the healthcare provider to assess the patient's heart rate before administering the medication to monitor for any signs of tachycardia. Giving levothyroxine with food may affect its absorption, so it is typically recommended to administer it on an empty stomach. Administering it in the evening is not necessary unless specifically prescribed by the healthcare provider, and giving it with calcium supplements can interfere with the absorption of levothyroxine.

Correct Answer: B

Rationale: The correct answer is B: Hypokalemia. Furosemide is a loop diuretic that can lead to potassium loss through urine, causing hypokalemia. Hyperkalemia (choice A) is not a side effect of furosemide. Hyponatremia (choice C) and hypernatremia (choice D) are related to sodium levels rather than potassium, and they are not typically associated with furosemide use.
