Correct Answer: A

Rationale: The correct answer is A: Improved academic performance. Physical activity has been shown to improve academic performance by enhancing concentration and cognitive function. This benefit is particularly important for elementary school students who are developing foundational skills. Choice B, increased social interactions, while important for overall development, may not directly relate to the academic aspect that the nurse is focusing on. Choice C, enhanced physical strength, is a valid benefit of physical activity but may not be as relevant to academic performance as the ability to concentrate and learn. Choice D, better sleep patterns, is also a valuable outcome of physical activity but is not as directly linked to academic performance as improved cognitive function.

Correct Answer: A

Rationale: The most important intervention for the nurse to implement prior to the discharge of a homeless client with alcohol dependency who had a tuberculin skin test prescribed is to identify how the client will follow-up to have the results read. This is crucial to ensure proper diagnosis and treatment. Providing written information (Choice B) is helpful but not as critical as ensuring the follow-up plan. Determining if the client understands the purpose of the test (Choice C) is important but not as immediate as ensuring the follow-up plan. Explaining when the results should be read (Choice D) is important, but the priority is to make sure the client has a plan in place for follow-up.

Correct Answer: D

Rationale: Respite care provides temporary relief for primary caregivers, allowing them to attend the reunion while ensuring the client is cared for.

Correct Answer: D

Rationale: In this scenario of severe hypertension (180/110 mm Hg), the nurse should prepare to administer Clonidine (Catapres), which is an antihypertensive medication commonly used to rapidly lower blood pressure in acute situations. Atenolol and Nifedipine are also antihypertensive medications, but Clonidine is more appropriate for immediate blood pressure reduction in this critical situation. Hydrochlorothiazide is a diuretic often used for long-term management of hypertension, not for rapid lowering of severely elevated blood pressure.

Correct Answer: B

Rationale: A nurse with Marfan syndrome who is postmenopausal can safely care for the client because Marfan syndrome does not affect the ability to care for this client, and postmenopausal status minimizes the risk of radiation exposure affecting reproductive health. Choice A is incorrect because pregnancy increases the risk of radiation exposure to the fetus. Choice C is incorrect because a nurse with a cold may have a compromised immune system and should not be exposed to radiation therapy. Choice D is incorrect because lactation can increase the risk of radiation exposure to breast tissue.
