Correct Answer: C

Rationale: The correct answer is C: Risk for infection related to altered immunologic response. This is the priority nursing diagnosis for a patient preparing for hematopoietic stem cell transplant (HSCT) because the patient's immune system will be severely compromised post-transplant, leading to a high risk of infections. It is crucial to prioritize infection prevention to ensure the patient's safety and well-being. Choice A is incorrect because while fatigue is common in cancer patients, it is not the priority in this case where infection risk is higher. Choice B is incorrect as altered nutrition can be addressed after managing the risk for infection. Choice D is incorrect as body image disturbance is important but not as critical as preventing infections in this highly vulnerable patient population.

Correct Answer: B

Rationale: The correct answer is B because it directly addresses the patient's ethnohistory by asking about the differences in their life here compared to back home. This question helps the nurse understand the patient's cultural background, beliefs, and practices. Option A focuses solely on language, which is not sufficient to understand ethnohistory. Option C inquires about caregivers during sickness, which is important but does not specifically relate to ethnohistory. Option D compares treatment approaches, which is relevant but doesn't explore the broader cultural context as effectively as option B.

Correct Answer: D

Rationale: The correct answer is D. The nurse should arrange for a referral to a rehabilitation facility for vision training. This option directly addresses the patient's inability to read medication bottles accurately due to a vision problem. Vision training can help improve the patient's ability to manage medication independently. A: Asking the social worker to investigate alternative housing arrangements is not relevant to the patient's vision problem affecting medication management. B: Asking the social worker to investigate community support agencies may not directly address the patient's vision issue and medication management. C: Encouraging the patient to explore surgical corrections for the vision problem is not appropriate without considering less invasive options first, such as vision training.

Correct Answer: B

Rationale: The correct answer is B: Dribbling of urine. This finding should be followed up on after catheter removal because it may indicate urinary retention or incomplete bladder emptying, which can lead to complications such as urinary tract infection. A: Increasing fluid intake is important for overall hydration but is not a specific finding that requires follow-up after catheter removal. C: Voiding in small amounts may be a normal response initially after catheter removal and does not necessarily indicate a problem. D: Voiding within 6 hours of catheter removal is a positive sign of bladder function recovery and does not require immediate follow-up.

Correct Answer: C

Rationale: The correct answer is C because primary brain tumors originate from cells within the brain itself. These tumors develop from abnormal growth of brain cells. Choice A is incorrect as primary brain tumors do not come from outside the central nervous system (CNS). Choice B is incorrect as primary brain tumors do not typically start in glands. Choice D is incorrect as primary brain tumors do not arise from nerve tissue elsewhere in the body. In summary, the nurse should explain to the patient that the tumor originated from cells within his brain to provide accurate information about the nature of primary brain tumors.
