A 72-year-old woman is being assessed by the nurse for an annual physical. Which finding is of concern to the nurse?
- A. Thinning of pubic hair
- B. Increased size of the uterus
- C. Decreased size of the clitoris
- D. Loss of tone of the pelvic ligaments
Correct Answer: B
Rationale: The correct answer is B: Increased size of the uterus. In a 72-year-old woman, an increased size of the uterus can indicate potential issues such as fibroids or endometrial hyperplasia, which may require further investigation. Thinning of pubic hair (A) is a common age-related change. Decreased size of the clitoris (C) and loss of tone of the pelvic ligaments (D) can also occur with aging but are not typically concerning findings during a routine physical exam in this age group.

Morphology of fibrocytic disease:
- A. Apocrine metaplasia
- B. Proliferation of ductules
- C. Epithelial hyperplasia
- D. Giant cell
Correct Answer: C
Rationale: The correct answer is C: Epithelial hyperplasia. Fibrocytic disease involves nonproliferative and proliferative fibrocystic changes in the breast tissue. Epithelial hyperplasia is a common proliferative change seen in fibrocystic disease, characterized by increased number of epithelial cells in the ducts and lobules. Apocrine metaplasia, choice A, is another common change in fibrocystic disease but is not specific to morphology. Proliferation of ductules, choice B, is not a characteristic feature of fibrocystic disease. Giant cells, choice D, are not typically associated with fibrocystic changes.
The female genitive ducts include the following structures:
- A. uterus;
- B. vulva;
- C. vagina;
- D. ovary
Correct Answer: D
Rationale: The correct answer is D: ovary. The female genitive ducts refer to the structures involved in the production, transport, and release of eggs. The ovary is the primary organ responsible for producing eggs. The uterus, vulva, and vagina are not directly involved in egg production but rather in the reception, nurturing, and passage of the egg. Therefore, the ovary is the correct choice as it is a key structure in the female reproductive system responsible for egg production.
Prophase I of the spermatocyte phase lasts approximately:
- A. 2 hours
- B. 24 hours
- C. 2 days
- D. 16 days
Correct Answer: D
Rationale: The correct answer is D (16 days) because prophase I of spermatocyte phase involves complex processes like chromosome pairing and recombination, which take time. It is a crucial stage in sperm formation. Choices A, B, and C are incorrect as they underestimate the duration required for these intricate cellular events to occur. A shorter timeframe would not allow for proper genetic exchange and segregation, essential for genetic diversity in offspring. Thus, a longer duration like 16 days is necessary for the completion of prophase I in spermatocyte phase.
Which of these is not a function of testosterone?
- A. loss of body hair
- B. thickening of the larynx
- C. anabolism of skeletal muscle
- D. thickening of bones
Correct Answer: A
Rationale: The correct answer is A, loss of body hair. Testosterone is responsible for thickening of the larynx, anabolism of skeletal muscle, and thickening of bones. It promotes growth and development of male secondary sexual characteristics, such as increased body hair. Therefore, loss of body hair is not a function of testosterone. Choice B, thickening of the larynx, is correct because testosterone contributes to the deepening of the voice by thickening the vocal cords. Choice C, anabolism of skeletal muscle, is correct as testosterone enhances protein synthesis in muscles, leading to muscle growth. Choice D, thickening of bones, is correct because testosterone promotes bone growth and mineralization.
The outer serosal layer of the uterus is the _____.
- A. perimetrium
- B. cervix
- C. endometrium
- D. myometrium
Correct Answer: A
Rationale: The correct answer is A: perimetrium. The perimetrium is the outer serosal layer of the uterus, providing protection and support. The other choices are incorrect: B. cervix is the lower portion of the uterus, C. endometrium is the inner lining where implantation occurs, and D. myometrium is the middle muscular layer of the uterus. The perimetrium is the outermost layer, making it the correct choice.
