Correct Answer: D

Rationale: Blue-gray skin discoloration is a common sign of Amiodarone toxicity, known as blue-gray discoloration, which can affect areas like the face, neck, or hands. It is important to monitor for this side effect, as it can be a visible indicator of potential toxicity. Choices A, B, and C are incorrect. Light yellow urine is not typically associated with Amiodarone toxicity. Tinnitus is not a common manifestation of Amiodarone toxicity. A productive cough is not a recognized symptom of Amiodarone toxicity.

Correct Answer: A

Rationale: Corrected Rationale: Hydrochlorothiazide is a diuretic known to cause electrolyte imbalances, particularly hyponatremia (low sodium levels). The nurse should closely monitor the client for signs of hyponatremia by assessing their electrolyte levels. Choice B, Hyperkalemia, is incorrect as hydrochlorothiazide is more likely to cause hypokalemia (low potassium levels) rather than hyperkalemia. Choice C, Hypercalcemia, is incorrect because hydrochlorothiazide is not known to cause increased calcium levels. Choice D, Hypoglycemia, is also incorrect as it is not a common adverse effect of hydrochlorothiazide.

Correct Answer: B

Rationale: When a client is prescribed Clopidogrel, an antiplatelet medication, the nurse should instruct them to avoid taking aspirin or other NSAIDs. This is because both medications can increase the risk of bleeding when taken together, potentially leading to serious health complications. Therefore, it is crucial for the client to follow this instruction to ensure their safety and well-being while on Clopidogrel. Choices A, C, and D are incorrect because taking Clopidogrel with food, avoiding foods high in potassium, or taking the medication at bedtime are not specific instructions related to the safe use of Clopidogrel and do not address the potential interaction with aspirin, which is essential for the client's well-being.

Correct Answer: A

Rationale: Constipation is a common adverse effect of Verapamil, a calcium channel blocker. Verapamil can slow down bowel movements and lead to constipation as a side effect. Therefore, the client reporting frequent constipation should alert the nurse to a potential adverse effect of Verapamil. Choices B, C, and D are not typically associated with Verapamil use. Increased urination is not a common side effect of Verapamil, peeling skin is more likely related to a dermatological issue, and ringing in the ears is not a known adverse effect of Verapamil.

Correct Answer: B

Rationale: Enalapril, an ACE inhibitor, can cause hyperkalemia as an adverse effect due to decreased aldosterone levels, leading to potassium retention. Monitoring potassium levels is essential to prevent complications associated with hyperkalemia. Bradycardia (Choice A) is not a common adverse effect of Enalapril. Enalapril does not typically affect glucose levels, so hypoglycemia (Choice C) is not a common concern with this medication. Enalapril does not directly impact calcium levels, so hypocalcemia (Choice D) is not a typical adverse effect.
