In male embryos, which hormone is responsible for the development of the urethra, prostate, and external genitals?
- A. dihydrotestosterone (DHT)
- B. FSH
- C. Progesterone
- D. Estrogen
Correct Answer: A
Rationale: The correct answer is A: dihydrotestosterone (DHT). DHT is a potent form of testosterone responsible for male sexual development, including the formation of the urethra, prostate, and external genitals. It binds to androgen receptors in target tissues, promoting their growth and differentiation. FSH (Choice B) is follicle-stimulating hormone, which primarily regulates sperm production in males. Progesterone (Choice C) is a female sex hormone involved in the menstrual cycle and pregnancy. Estrogen (Choice D) is a female sex hormone responsible for female reproductive development. Thus, A is the correct answer as it specifically pertains to male sexual differentiation.

A nurse is teaching a client in the doctor's office about genital warts. Which of the following is the best discharge instruction to give to a client with genital warts?
- A. Advise all sexual contacts to be examined and treated.
- B. Antiviral IV drugs are recommended to prevent viral shedding.
- C. Topical applications of the antiviral drugs are recommended for clinical benefits.
- D. Use of alcohol, peroxide, witch hazel, and warm air from a hair dryer are recommended to keep the lesions dry.
Correct Answer: A
Rationale: Notifying and treating all sexual contacts is essential to prevent further spread of genital warts.
The evolutionary stages of the ovarian follicles are:
- A. secondary;
- B. tertiary (de Graaf);
- C. primordial;
- D. evolutionary;
Correct Answer: C
Rationale: The correct answer is C: primordial. Ovarian follicles go through several stages of development. Primordial follicles are the earliest stage, containing primary oocytes surrounded by a single layer of squamous cells. This stage represents the resting pool of follicles. Secondary follicles come next, with primary oocytes surrounded by multiple layers of granulosa cells. Tertiary (de Graaf) follicles are the most advanced stage, containing a fluid-filled antrum and a mature oocyte. Evolutionary is not a recognized stage in ovarian follicle development. Secondary is incorrect as it comes after primordial, and tertiary is incorrect as it is not the earliest stage.
When menstruation ends in middle age:
- A. Menopause
- B. Gestation
- C. Implantation
- D. uterus
Correct Answer: A
Rationale: The correct answer is A: Menopause. Menopause refers to the natural cessation of menstruation in middle-aged women, typically around the age of 45-55. It occurs due to declining levels of estrogen and progesterone hormones, leading to the end of reproductive capacity. Gestation (B) refers to pregnancy, not the cessation of menstruation. Implantation (C) is the process of a fertilized egg attaching to the uterus, not related to the end of menstruation. Uterus (D) is an organ involved in menstruation but does not specifically refer to the cessation of menstruation in middle age.
A client is concerned about her irregular menstrual periods since she has increased her daily workouts at the gym to 2 hours each day. What is the nurses’ best response?
- A. “Do you want to talk about the need for that much exercise?”
- B. “Exercise is healthy but can decrease body fat and cause irregular periods.”
- C. “Bingeing and purging can cause electrolyte problems in your body.”
- D. “Anorexic behavior can result in decreased estrogen levels.”
Correct Answer: B
Rationale: Rationale:
The correct answer is B because excessive exercise can lead to decreased body fat, which in turn disrupts hormone levels causing irregular periods. Choice A is inappropriate as it doesn't address the underlying issue. Choices C and D are incorrect as they refer to different conditions (bulimia and anorexia) not related to the client's concern.
The ovarian phase between the end of menstruation and beginning of ovulation is the
- A. Menstrual phase
- B. Preovulatory phase
- C. Proliferative phase
- D. Follicular phase
Correct Answer: C
Rationale: The correct answer is C: Proliferative phase. During this phase, the endometrium thickens in preparation for a potential implantation of a fertilized egg. This phase occurs after the menstrual phase and before ovulation, marking the time when the ovarian follicles are developing under the influence of FSH. The other choices are incorrect because the menstrual phase (A) refers to the shedding of the endometrium, the preovulatory phase (B) occurs just before ovulation, and the follicular phase (D) includes both the menstrual and preovulatory phases.
