Correct Answer: B

Rationale: The Cowper glands, also known as bulbourethral glands, are a pair of small exocrine glands located below the prostate gland, within the posterior aspect of the male urethra. These glands are responsible for producing a clear, viscous fluid that helps lubricate the urethra, neutralize acidic urine remnants, and provide a conducive environment for sperm to survive in the urethra. Inflammation of the Cowper glands can result in conditions such as urethritis or other discomfort related to the male reproductive system.

Correct Answer: D

Rationale: Radical trachelectomy is a surgical procedure that involves the removal of the cervix while preserving the uterus. This procedure is often offered to young women diagnosed with early-stage cervical cancer who wish to preserve their fertility and have children in the future. By removing the cervix and part of the upper vagina, while leaving the uterus intact, radical trachelectomy offers these patients a chance at preserving their ability to conceive and carry a pregnancy to term. It is a fertility-sparing option in the management of cervical cancer, particularly in younger patients like the 25-year-old mentioned in the question.

Rationale: Megestrol is a synthetic progestational agent that has been found to promote significant weight gain in AIDS patients with wasting syndrome by increasing body fat stores. It is commonly used to stimulate appetite and increase caloric intake in patients experiencing anorexia and weight loss due to various medical conditions, including AIDS-related wasting. Megestrol works by increasing appetite and improving food intake, leading to weight gain and improved nutritional status in patients with HIV/AIDS. It has been shown to be effective in reversing weight loss and improving quality of life in these patients. Therefore, the drug megestrol is the most appropriate choice for promoting weight gain in AIDS patients with wasting syndrome and anorexia.

Correct Answer: A

Rationale: A person whose vision is measured at 20/40 can see an object from 40 feet away that a person with 20/20 vision can see from 20 feet away. In this measurement system, the first number represents how far away the person is from the eye chart (the testing distance), and the second number indicates how far away a person with normal vision can be from the chart to see the same line of letters or objects. Therefore, if someone has 20/40 vision, it means they need to be at 20 feet to see what a person with 20/20 vision can see at 40 feet.
