Correct Answer: A

Rationale: A TPN solution with an oily appearance and a layer of fat on top indicates that the solution is 'cracked' and should not be used as it may have separated or deteriorated. This finding suggests a need to obtain a new bag of TPN before administering. Options B, C, and D are normal aspects of TPN administration. Option B confirms the presence of essential components in the TPN solution, option C provides information about the preparation time, and option D ensures proper identification and matching of the TPN with the correct client.

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.

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: D

Rationale: The correct answer is D: Limit alcohol and nicotine prior to bedtime. Alcohol and nicotine are stimulants that can disrupt sleep patterns, so avoiding them before bedtime can promote better sleep. Choices A, B, and C are incorrect. Consuming a warm drink at bedtime may lead to frequent urination, disrupting sleep; taking an evening walk before bedtime may increase alertness rather than inducing sleep; and taking an afternoon nap can make it harder to fall asleep at night.

Correct Answer: B

Rationale: The correct answer is B. Prednisone can cause weight gain and other side effects, so clients should be informed about these potential risks. Choice A is incorrect because prednisone should not be stopped abruptly to prevent withdrawal symptoms. Choice C is incorrect because prednisone can have various side effects. Choice D is incorrect because prednisone is usually prescribed with specific dosing instructions and should not be taken irregularly or only when symptoms occur.
