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?

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.

Correct Answer: A

Rationale: The correct answer is A: It produces the hormone hCG. The placenta is responsible for producing the hormone human chorionic gonadotropin (hCG), which is essential for maintaining pregnancy by supporting the corpus luteum to produce progesterone. This hormone is also detected in pregnancy tests. Choice B is incorrect because the placenta does not stimulate development of the follicle; rather, it supports the corpus luteum. Choice C is incorrect as the implantation site for the developing embryo is the endometrium of the uterus, not the placenta itself. Choice D is incorrect because the placenta does not stimulate the development of the corpus luteum; instead, it supports its function through hCG production.

Correct Answer: A

Rationale: The correct answer is A because spermatogonia are indeed germ cells that give rise to sperm cells through the process of spermatogenesis. They are diploid cells, not male gametes. Spermatogonia do not have flagella; instead, mature sperm cells have flagella for motility. So, the correct answer is A because spermatogonia are the precursor cells for sperm cells, they are diploid, and they do not have flagella.

Correct Answer: B

Rationale: The correct answer is B: Uterus. During a bimanual pelvic examination, the examiner can palpate the uterus between their fingers. The uterus is a key structure that can be felt for its size, shape, and position. The ovaries, fallopian tubes, and cervix are not typically felt during a bimanual exam as they are located deeper within the pelvis and are not easily palpable. Palpating the ovaries directly is not typically part of a routine pelvic examination due to their small size and position behind the uterus. The fallopian tubes are also not typically palpable during a bimanual exam as they are located laterally to the uterus. The cervix may be felt during the exam, but it is not the main structure that is typically palpated during a bimanual pelvic examination.

Correct Answer: C

Rationale: Correct Answer: C - Ectopic pregnancy Rationale: 1. IUDs do not prevent ectopic pregnancies. 2. IUD insertion increases the risk of ectopic pregnancy. 3. Ectopic pregnancy is a serious complication of IUD use. Summary of other choices: A: Young age - Age alone is not a contraindication. B: Nulliparity - Being nulliparous is not a contraindication. D: Abnormal uterine bleeding - It is a relative, not absolute contraindication.
