Correct Answer: A

Rationale: The correct answer is A. When a client reports drowsiness while taking clonidine, the nurse should assess how long the client has been taking the medication. Drowsiness is a common side effect that can occur in the early weeks of treatment with clonidine. By understanding the duration of medication use, the nurse can determine if the drowsiness is a temporary effect that may decrease over time. Choices B, C, and D are incorrect because assessing the client's dietary habits, checking for signs of infection, or evaluating the client's sleep pattern would not directly address the drowsiness associated with clonidine use.

Correct Answer: A

Rationale: A serum calcium level of 11 mg/dL indicates hypercalcemia, which can be a complication of hyperparathyroidism and requires immediate intervention. Hypercalcemia can lead to serious complications such as cardiac dysrhythmias, renal failure, and neurologic symptoms. Monitoring and managing serum calcium levels are crucial in clients with hyperparathyroidism. Serum phosphorus, magnesium, and albumin levels are important to assess in clients with hyperparathyroidism, but they do not require immediate intervention as hypercalcemia poses a more urgent risk.

Correct Answer: A

Rationale: The correct answer is A, Graves' disease. The symptoms described in the client are classic manifestations of hyperthyroidism, which is commonly caused by Graves' disease, an autoimmune condition affecting the thyroid. Weight loss, racing heart rate, difficulty sleeping, moist skin with fine hair, prominent eyes, lid retraction, and a staring expression are all indicative of hyperthyroidism. Choice B, Cushing's syndrome, is characterized by weight gain, hypertension, and a rounded face due to excess cortisol. Choice C, Addison's disease, presents with symptoms such as weight loss, fatigue, and hyperpigmentation due to adrenal insufficiency. Choice D, hypothyroidism, typically features symptoms opposite to those described in the client, such as weight gain, bradycardia, and dry skin.

Correct Answer: D

Rationale: Individuals who are homeless and have a history of alcoholism are at the highest risk for presenting with TB in this scenario. Homeless individuals often live in crowded conditions with poor ventilation, increasing the likelihood of TB transmission. Additionally, alcoholism can weaken the immune system, making individuals more susceptible to developing TB. The other options, such as a daycare worker, an office worker, or a high school student, do not inherently carry the same level of risk factors for TB transmission as being homeless with a history of alcoholism.
