Correct Answer: A

Rationale: The correct answer is A: Diabetes. Erectile dysfunction can be caused by organic factors, such as diabetes, which affects blood flow and nerve function. Diabetes can lead to damage of blood vessels and nerves, impacting the ability to achieve and maintain an erection. Testosterone deficiency (choice B) can also contribute to erectile dysfunction, but it is not an organic cause. Anxiety (choice C) and depression (choice D) are psychological factors that can lead to erectile dysfunction, not organic causes. Parkinsonism (choice E) can affect sexual function, but it is not a common organic cause of erectile dysfunction.

Correct Answer: D

Rationale: The correct answer is D, performance of pelvic muscle exercises. Pelvic muscle exercises, also known as Kegel exercises, help strengthen the pelvic floor muscles which support the bladder, uterus, and bowel. By strengthening these muscles, the risk of developing cystocele, rectocele, and uterine prolapse postpartum is reduced. It is a proactive approach to prevent these conditions. Choice A, maintenance of good perineal hygiene, is important for preventing infections but does not specifically address the risk of pelvic organ prolapse. Choice B, prevention of constipation, is also important but does not directly target the muscle weakness that contributes to prolapse. Choice C, increased fluid intake for 2 weeks postpartum, is not as effective in preventing prolapse as pelvic muscle exercises. In summary, pelvic muscle exercises are the most appropriate recommendation as they directly address strengthening the muscles that support the pelvic organs, reducing the risk of prolapse postpartum.

Parkinsonism (choice E) can affect sexual function, but it is not a common organic cause of erectile dysfunction.

Correct Answer: C

Rationale: Rationale: Option C is correct because adequate hydration helps prevent hypercalcemia by promoting the excretion of excess calcium in the urine. This reduces the risk of calcium buildup in the blood. Consuming 2 to 4 liters of fluid daily ensures proper hydration, which is crucial for patients at risk for hypercalcemia. Stool softeners (Option A) are not contraindicated and can help prevent constipation, which may be a side effect of some cancer treatments. Laxatives (Option B) should not be taken daily as they can lead to dehydration and electrolyte imbalances. Restricting calcium intake (Option D) is not the primary intervention for preventing hypercalcemia; rather, maintaining adequate hydration is key.

Correct Answer: A

Rationale: The correct answer is A because administering a lethal dose of medication to a patient whose death is imminent directly causes the patient's death, constituting assisted suicide. This action is intentional and aims to end the patient's life. In contrast, choices B, C, and D do not involve intentionally causing the patient's death. Choice B involves a medication error but not with the intent to end the patient's life. Choice C respects the patient's autonomy in refusing treatment. Choice D honors the patient's wishes for end-of-life care. Thus, only choice A aligns with the definition of assisted suicide.
