Structurally, the ovary displays:
- A. on the outside, an elastic tissue;
- B. on the surface, the glandular parenchyma;
- C. the cortical area, which contains ovarian follicles;
- D. the medullar area, which contains blood vessels;
Correct Answer: C
Rationale: Step 1: The ovary is a complex organ with distinct internal structures.
Step 2: The ovarian cortex houses ovarian follicles, which are crucial for reproductive functions.
Step 3: Ovarian follicles contain oocytes and support cells for oocyte development.
Step 4: Therefore, choice C is correct as it accurately describes the structural aspect of the ovary.
Summary: Choices A, B, and D are incorrect as they do not accurately describe the structural components of the ovary. Choice A talks about elastic tissue, choice B mentions glandular parenchyma, and choice D refers to blood vessels, none of which are specific to the structural arrangement of the ovary.

The external male reproductive organs consist of the penis, testes, and
- A. urethra
- B. prostate
- C. scrotum
- D. seminal vesicle
Correct Answer: C
Rationale: The correct answer is C: scrotum. The scrotum is a pouch of skin that houses the testes, which are responsible for producing sperm and testosterone. It is considered an external male reproductive organ because it plays a crucial role in maintaining the optimal temperature for sperm production. The penis is also an external male reproductive organ, but it is not part of the scrotum. The urethra is a passage for both urine and semen, and while it is part of the male reproductive system, it is not considered an external reproductive organ. The prostate and seminal vesicle are internal male reproductive organs involved in producing and secreting seminal fluid, making them incorrect choices in this context.
What hormone(s) stimulates the growth of the endometrium during the proliferative phase of the uterine (menstrual) cycle?
- A. Estrogens
- B. Progesterones
- C. Insulin
- D. Testosterone
Correct Answer: A
Rationale: Estrogens stimulate growth of the endometrium during the proliferative phase by promoting cell proliferation and thickening of the endometrial lining. Estrogens also increase blood flow to the endometrium. Progesterone, on the other hand, prepares the endometrium for implantation and supports pregnancy, but does not directly stimulate growth during the proliferative phase. Insulin and testosterone do not have direct roles in stimulating endometrial growth during this phase.
A young woman is given daily injections of a substance beginning on the 16th day of her normal menstrual cycle and continuing for 3 weeks. As long as the injections continue, she does not menstruate. The injected substance could be which of the following?
- A. Testosterone
- B. FSH
- C. An inhibitor of progesterone’s actions
- D. A prostaglandin E2 inhibitor
Correct Answer: C
Rationale: The correct answer is C: An inhibitor of progesterone’s actions. Progesterone is responsible for maintaining the uterine lining, and inhibiting its actions would prevent menstruation. Testosterone (A) and FSH (B) do not directly affect menstruation. Prostaglandin E2 (D) is involved in the menstrual process, but inhibiting it would not necessarily stop menstruation.
The nurse monitors a client who has gone through an endoscopic examination. Following a culdoscopy, what does a nurse need to observe for in this client?
- A. The nurse observes the client for any discomfort in the shoulders.
- B. The nurse observes the client for the signs of internal bleeding and the symptoms of shock.
- C. The nurse observes the client for changes in skin color and for any rise in body temperature.
- D. The nurse observes the quantity and frequency of urinary output.
Correct Answer: A
Rationale: Discomfort in the shoulders is a common side effect after culdoscopy due to gas insufflation.
The menstrual cycle lasts on average 28 days. Day 1 is the first day that ___________ starts, and usually finishes by day 5
- A. Menopause
- B. ovulation
- C. Implantation
- D. menstruation
Correct Answer: D
Rationale: The correct answer is D: menstruation. Day 1 of the menstrual cycle is the first day of menstruation, which typically lasts around 3-7 days. Menstruation is the shedding of the uterine lining when pregnancy has not occurred. This marks the beginning of a new cycle. Menopause (A) is the cessation of menstruation and fertility typically occurring in women in their 40s-50s. Ovulation (B) is the release of an egg from the ovary, usually occurring around day 14 of the cycle. Implantation (C) is the attachment of a fertilized egg to the uterus, which occurs around 6-10 days after ovulation.
