Correct Answer: B

Rationale: The correct answer is B. Monitoring for signs of restlessness, sweating, and excessive weight loss during thyroid replacement therapy is essential in managing hyperthyroidism. Restlessness can indicate increased metabolic rate, sweating can be due to excessive heat production, and weight loss can be a sign of overactive thyroid function. Providing extra blankets (Choice A) may worsen symptoms of heat intolerance. Balancing activity and rest (Choice C) is important, but not specific to hyperthyroidism. Encouraging activity to prevent constipation (Choice D) is not directly related to managing hyperthyroidism.

Correct Answer: A

Rationale: The correct answer is A: abdominal pain related to decreased peristalsis. Ulcerative colitis causes inflammation and ulcers in the colon, leading to abdominal pain due to decreased peristalsis. This impairs the movement of stool through the colon, resulting in pain. Choice B is incorrect as diarrhea is a common symptom of ulcerative colitis, not hyperosmolar intestinal contents. Choice C is incorrect as ulcerative colitis often leads to diarrhea and not fluid volume excess. Choice D is incorrect as activity intolerance is not directly related to ulcerative colitis, whereas abdominal pain is a common symptom associated with the condition.

Correct Answer: C

Rationale: The correct answer is C: "Take zidovudine every 4 hours around the clock." Zidovudine is an antiretroviral medication used to treat HIV/AIDS. It is crucial for the client to adhere to the prescribed dosing schedule to maintain therapeutic blood levels. Taking the medication every 4 hours around the clock helps to ensure consistent levels in the body, maximizing its efficacy. Taking it with meals (choice A) or on an empty stomach (choice B) is not specifically indicated for zidovudine. Choice D is incorrect as taking OTC drugs without consulting a healthcare provider can lead to drug interactions or adverse effects. Hence, choice C is the most appropriate instruction to ensure the client benefits from the medication.

Correct Answer: D

Rationale: The correct answer is D: leukocytosis. Carbamazepine can cause bone marrow suppression, leading to leukocytosis. Monitoring for elevated white blood cell count is essential to detect this potential complication early. A: Adult respiratory distress syndrome is not a common complication of carbamazepine. B: Elevated levels of phenytoin is not a direct complication of carbamazepine use. C: Diplopia is a common side effect of carbamazepine, not a potential complication like leukocytosis.

Correct Answer: C

Rationale: Rationale: Choice C is the correct answer because drinking lots of water at night actually helps prevent UTIs by flushing out bacteria from the urinary tract. Holding the urge to urinate (Choice A) can increase the risk of UTIs as bacteria can multiply in stagnant urine. Insertion of instruments and catheters (Choice B) can introduce bacteria, leading to infection. Unhygienic cleaning after defecation (Choice D) can also introduce bacteria to the urinary tract, causing UTIs. Therefore, Choice C is the exception as it does not contribute to the common causes of UTIs.
