Correct Answer: B

Rationale: The correct answer is to 'Monitor for dyskinesia.' Carbidopa-levodopa can cause dyskinesia as a side effect, characterized by involuntary movements. Monitoring for this side effect is crucial. Choice A is incorrect because carbidopa-levodopa helps manage symptoms of Parkinson's disease but does not cure it. Choice C is incorrect because carbidopa-levodopa should be taken on an empty stomach to enhance absorption. Choice D is incorrect because carbidopa-levodopa is not an opioid medication.

Correct Answer: A

Rationale: Corrected Rationale: Digitalis toxicity is a serious complication of digoxin therapy, particularly in older adults. Early symptoms include anorexia, nausea, and generalized weakness. Anorexia and weakness are common indicators of digitalis toxicity. Hyperactivity, hunger, tachycardia, increased urination, polyphagia, and polydipsia are not typical signs of digitalis toxicity. Monitoring for anorexia and weakness can help detect toxicity early and prevent life-threatening arrhythmias.

Correct Answer: B

Rationale: The correct answer is to verify the client's blood glucose level first before administering insulin. This step is crucial to determine the appropriate dose of insulin based on the client's current blood glucose level. Checking the expiration date (Choice A) is important but not the first step in this scenario. Obtaining the client's weight (Choice C) is not directly related to the immediate administration of insulin. Assessing for signs of hypoglycemia (Choice D) should be done after administering insulin to monitor for potential side effects or adverse reactions.

Correct Answer: A

Rationale: Administering pain medications as prescribed is a priority to manage chronic pain effectively. Pain medications help alleviate the client's discomfort and improve their quality of life. Encouraging physical activity, monitoring for depression, and educating about alternative therapies are important interventions but may not directly address the immediate need for pain relief in a client with chronic pain. Physical activity and alternative therapies can be beneficial as part of a holistic pain management plan, but addressing the pain directly should be the initial priority.

Correct Answer: C

Rationale: The correct adverse effect associated with vancomycin therapy is an infusion reaction, known as Red Man Syndrome. This reaction presents with rashes, flushing, tachycardia, and hypotension. It is essential to administer vancomycin over at least 60 minutes to prevent these symptoms. Hepatotoxicity, constipation, and immunosuppression are not commonly associated with vancomycin use. Ototoxicity and renal toxicity are significant risks with prolonged vancomycin therapy.
