The client on amiodarone develops symptoms of hypothyroidism. What is the nurse's best response?

Correct Answer: C

Rationale: The correct response is C: Monitor the client's thyroid function tests regularly. This is the best approach because amiodarone can cause hypothyroidism, so monitoring thyroid function tests allows early detection and appropriate management. Option A is not necessary unless the client presents with severe symptoms. Option B is incorrect as hypothyroidism is a serious side effect that requires monitoring and possible treatment adjustments. Option D is not recommended as abruptly stopping amiodarone can lead to serious cardiac arrhythmias. Regular monitoring ensures timely intervention if thyroid levels are abnormal.

Correct Answer: B

Rationale: The correct answer is B because blurred vision can be a serious side effect of amiodarone indicating potential optic nerve damage. Instructing the client to report this symptom to the healthcare provider immediately is crucial for further evaluation and management. Choice A is incorrect as blurred vision should not be dismissed as a common side effect. Choices C and D are incorrect as advising the client to stop or discontinue the medication abruptly can be harmful and should only be done under healthcare provider guidance.

Correct Answer: A

Rationale: The correct response is to administer acetaminophen as prescribed for the headache. This is because headaches are a common side effect of nitroglycerin due to vasodilation. Acetaminophen can help relieve the headache without interfering with the therapeutic effects of nitroglycerin. Holding the next dose (B) is not appropriate as it can lead to inadequate treatment of the client's condition. Discontinuing nitroglycerin (C) abruptly can be dangerous as it may cause rebound hypertension. Notifying the healthcare provider (D) is not necessary unless the headache persists or worsens.

Correct Answer: D

Rationale: The primary effect of a calcium channel blocker on the heart is to decrease blood pressure. Calcium channel blockers block the entry of calcium into the smooth muscle cells of blood vessels and the heart. This causes vasodilation and reduces the force of contraction in the heart, leading to a decrease in blood pressure. Choices A and B are incorrect as calcium channel blockers typically do not directly affect heart rate. Choice C is incorrect because calcium channel blockers actually tend to lower blood pressure rather than increase it.

Correct Answer: A

Rationale: Rationale for Correct Answer A: The nurse should notify the healthcare provider immediately because a cough can be a sign of a serious side effect of amiodarone called pulmonary toxicity. Prompt action is necessary to prevent further complications. The healthcare provider needs to assess the client, possibly order diagnostic tests, and determine the appropriate course of action. Summary of Incorrect Choices: B: Reassuring the client without further assessment could lead to delayed recognition of a serious issue. C: Continuing amiodarone without addressing the cough may worsen the condition. D: Discontinuing amiodarone without consulting the healthcare provider may not be appropriate and could lead to adverse effects or worsening of the client's condition.
