Correct Answer: A

Rationale: The correct answer is A because sildenafil works by enhancing the effects of nitric oxide, which is released during sexual stimulation to relax the muscles in the penis and increase blood flow for an erection. Therefore, sexual stimulation is necessary for the medication to be effective. Explanation of other choices: B: While sildenafil is typically taken 30 minutes to 4 hours before sexual activity, it does not need to be exactly 1 hour prior. C: Facial flushing and headache are common side effects of sildenafil but do not require immediate reporting unless severe or persistent. D: Sildenafil may cause temporary visual disturbances like changes in color vision, but permanent visual changes are rare.

Correct Answer: D

Rationale: The correct answer is D: Incentives to palliative care. Palliative care focuses on improving the quality of life for patients with serious illnesses by addressing their physical, emotional, and spiritual needs. As the American population ages, the emphasis on palliative care in long-term care facilities is crucial. Regulations emphasizing incentives for palliative care ensure that patients receive appropriate symptom management, comfort care, and support to enhance their overall well-being. Choice A: Ongoing acute care is not the correct answer because palliative care is different from acute care, which focuses on treating the underlying medical condition. Choice B: Restorative measures are not the correct answer as palliative care aims to improve quality of life rather than focusing on restoring physical function. Choice C: Mobility and socialization are important aspects of care in long-term facilities, but palliative care goes beyond these aspects to provide holistic support for patients facing serious illnesses.

Correct Answer: A

Rationale: The correct answer is A: Provide emotional support to the patient and her family. This is the priority as the patient has received devastating news and needs immediate support. Emotional support can help the patient cope with the diagnosis, express feelings, and make decisions. B: Implementing distraction techniques may not address the patient's emotional needs in this critical situation. C: Offering to inform the family of the diagnosis is important but not the priority at this moment. D: Teaching about maintaining a positive attitude may not be appropriate as the patient is facing a terminal illness.

Correct Answer: C

Rationale: The correct answer is C: Apply petroleum jelly to the affected area. This is because petroleum jelly helps to soothe and protect the skin, reducing dryness and irritation caused by radiation therapy. Ice (A) can further damage the skin, shaving (B) can increase the risk of infection, and soap (D) can be too harsh on the sensitive skin. Therefore, instructing the patient to apply petroleum jelly is the most appropriate recommendation to promote skin healing and comfort.

Correct Answer: A

Rationale: The correct answer is A: Tumor lysis syndrome (TLS). In this scenario, the oncology patient has completed treatment for non-Hodgkin lymphoma. TLS is a potential complication post-treatment due to the rapid breakdown of cancer cells, leading to release of intracellular contents like potassium, phosphorus, and uric acid into the bloodstream. This can result in electrolyte imbalances, renal failure, and cardiac arrhythmias. The nurse should assess for signs such as hyperkalemia, hyperphosphatemia, hypocalcemia, and elevated uric acid levels. Monitoring renal function and fluid status is crucial. Summary of other choices: B: Syndrome of inappropriate ADH (SIADH) is characterized by excessive release of antidiuretic hormone leading to water retention and dilutional hyponatremia. Not typically associated with post-treatment complications in oncology patients. C: Disseminated intravascular coagulation (DIC)
