Correct Answer: C

Rationale: Step 1: After mastoid surgery, patients may experience pain and dizziness, hence addressing the safe use of analgesics and antivertiginous agents is crucial for symptom management. Step 2: Analgesics help in managing post-operative pain, while antivertiginous agents help control dizziness, reducing the risk of falls. Step 3: Educating the patient on safe use ensures proper pain and symptom management, preventing complications. Step 4: Other choices are incorrect as they do not directly address immediate post-operative care needs such as pain and dizziness management.

Correct Answer: C

Rationale: Rationale: Choice C is correct because understanding the illness from the patient's perspective helps nurses provide individualized care. By empathizing with the patient's experience, nurses can tailor support to meet their specific needs. Describing personal experiences (A) may not be appropriate as it shifts the focus from the patient. Encouraging fighting for a cure (B) may not align with the patient's wishes for quality of life. Assisting with life review (D) can be beneficial but may not be a priority for all patients. Providing interventions for end-of-life closure (E) is important, but understanding the illness from the patient's perspective (C) forms the foundation for effective support.

Correct Answer: C

Rationale: The correct answer is C because providing realistic emotional preparation for death is a priority in caring for a patient with a terminal illness like leukemia. This helps the patient and their loved ones cope with the impending loss and make the most of the time left. Option A focuses solely on prolonging life, which may not align with the patient's wishes. Option B, providing financial advice, is important but not the top priority in this situation. Option D, maximizing family social interactions after the patient's death, is not immediate and does not address the patient's emotional needs.

Correct Answer: B

Rationale: The correct answer is B because hearing loss and tinnitus caused by aspirin are typically irreversible. Aspirin is known to cause ototoxicity, which can lead to permanent damage to the auditory system. The nurse should inform the patient that the hearing loss and tinnitus may not improve even after discontinuing aspirin. Choice A is incorrect because hearing loss caused by aspirin is usually permanent. Choice C is incorrect because aspirin is a known cause of tinnitus and hearing loss. Choice D is incorrect because tolerance to aspirin does not prevent or reverse ototoxic effects like tinnitus and hearing loss.

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.
