Correct Answer: A

Rationale: The correct answer is A: Utilize a pressure-reducing mattress. This intervention is crucial for preventing pressure ulcers in patients at risk for impaired skin integrity, such as those with HIV. By redistributing pressure, a pressure-reducing mattress helps to alleviate pressure on vulnerable areas, reducing the risk of skin breakdown. Limiting physical activity (B) can lead to muscle atrophy and worsen skin integrity. Applying antibiotic ointment (C) may not address the root cause of skin breakdown. Avoiding synthetic fabrics (D) may be helpful in some cases, but it is not as effective as using a pressure-reducing mattress.

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: B

Rationale: The correct order is B: Kidney, ureters, bladder, urethra. 1. Kidneys filter blood and produce urine. 2. Ureters transport urine from kidneys to bladder. 3. Bladder stores urine until expelled. 4. Urethra carries urine from bladder out of the body. Other choices are incorrect because they do not follow the anatomical flow of urine through the urinary system.

Correct Answer: C

Rationale: The correct answer is C because African-American ethnicity and previous cesarean birth are established risk factors for placenta previa due to the potential for scarring and abnormal placental implantation. Male fetus does not influence the risk. Asian-American ethnicity and previous preterm birth are not significant risk factors. European-American ethnicity and previous spontaneous abortion are also not associated with an increased risk of placenta previa.

Correct Answer: B

Rationale: The correct answer is B: Vulvodynia. Vulvodynia is characterized by chronic vulvar pain or discomfort, including stabbing pain and burning, without an identifiable cause. In this case, the young girl is experiencing these symptoms despite not being sexually active, ruling out other conditions like vulvitis (inflammation of the vulva), vaginitis (inflammation of the vagina), and Bartholin's cyst (fluid-filled swelling near the vaginal opening). The absence of sexual activity suggests that the pain is not related to an infection or trauma, further supporting the diagnosis of vulvodynia.
