2. The vulva (C) is the external genitalia and is not the structure between the uterus and the vagina.
3. The hymen (D) is a thin membrane at the opening of the vagina and does not serve as the structure between the uterus and the vagina.

- B. The skin covering the penis is hairless and loose.

A nurse is taking a health history of a male patient with a possible diagnosis of erectile dysfunction. Which of the following statements made by the patient would the nurse recognize as risk factors for erectile dysfunction?
- A. I have had type 1 diabetes mellitus since I was 8 years old.
- B. I frequently have urinary tract infections.
- C. I am taking medications to control my blood pressure.
- D. I have an enlarged prostate gland.
Correct Answer: A
Rationale: The correct answer is A because type 1 diabetes mellitus is a well-known risk factor for erectile dysfunction due to its impact on blood flow and nerve function. Diabetes can damage blood vessels and nerves that are essential for achieving and maintaining an erection. This patient's long history of type 1 diabetes increases the likelihood of developing erectile dysfunction.
Choices B, C, and D are incorrect because urinary tract infections, blood pressure medications, and an enlarged prostate gland are not directly associated with erectile dysfunction. Urinary tract infections typically do not affect erectile function, blood pressure medications may have erectile dysfunction as a side effect but are not a direct risk factor, and an enlarged prostate gland is more related to urinary symptoms rather than erectile dysfunction.
