The veins of the ovary can open into:
- A. inferior vena cava;
- B. uterine vein;
- C. renal vein;
- D. internal iliac vein;
Correct Answer: D
Rationale: The correct answer is D: internal iliac vein. The veins of the ovary drain into the ovarian veins, which then connect to the pampiniform plexus, ultimately draining into the internal iliac vein. This pathway allows for the blood from the ovary to be carried back to the heart. The other choices (A, B, C) are incorrect as the ovarian veins do not typically open into the inferior vena cava, uterine vein, or renal vein.

The contraction of the myoepithelial breast cells is stimulated by _____.
- A. estrogen
- B. progesterone
- C. oxytocin
- D. prolactin
Correct Answer: C
Rationale: The correct answer is C: oxytocin. Myoepithelial cells contract to facilitate milk ejection during breastfeeding. Oxytocin is the hormone responsible for stimulating this contraction. Estrogen and progesterone are involved in breast development and preparing for lactation but do not directly stimulate myoepithelial cell contraction. Prolactin is responsible for milk production but does not directly trigger myoepithelial cell contraction.
The menstrual cycle is triggered each month by
- A. the release of blood from the uterus
- B. the buildup of the lining of the uterus
- C. hormones
- D. sexual intercourse
Correct Answer: C
Rationale: The correct answer is C: hormones. Hormones, specifically estrogen and progesterone, control the menstrual cycle by regulating the release of an egg from the ovary, thickening the uterine lining, and preparing the body for pregnancy or menstruation. Hormonal fluctuations throughout the cycle signal the body to shed the uterine lining if fertilization does not occur. Choices A and B are incorrect as they describe events during the menstrual cycle rather than the trigger itself. Choice D, sexual intercourse, does not directly trigger the menstrual cycle but may lead to conception, which is one of the outcomes of the menstrual cycle.
Select the following structures which participate in forming the pelvic brim
- A. Arcuate line
- B. Margin ala of sacrum
- C. Pubic tubercle
- D. Sacral promontory
Correct Answer: A
Rationale: The correct answer is A: Arcuate line. The pelvic brim is formed by structures at the pelvic inlet. The arcuate line is a ridge on the inner surface of the ilium that contributes to the boundary of the pelvic brim. The other choices, B: Marginal ala of sacrum, C: Pubic tubercle, and D: Sacral promontory, do not directly participate in forming the pelvic brim. The marginal ala of the sacrum is part of the sacrum, the pubic tubercle is located on the pubis bone, and the sacral promontory is a landmark on the sacrum but does not contribute to the pelvic brim.
Which of the following suggestions should a nurse give a client with a prostate cancer to deal with his impotency?
- A. Abstain from any sexual activity.

- C. Practice sexual intercourse at least two to three times daily until successful.
- D. Perform pelvic floor retraining exercises.

What is line “D” pointing to?
- A. Follicular fluid
- B. Germinal epithelium
- C. Ovarian cortex
- D. Ovarian medulla
Correct Answer: D
Rationale: The correct answer is D: Ovarian medulla. Line "D" is pointing to the inner region of the ovary known as the medulla, which contains blood vessels, nerves, and connective tissue. This is confirmed by the location and characteristics of the structures in that region.
Explanation:
1. Follicular fluid (Choice A) is found within the follicles in the ovarian cortex, not in the medulla.
2. Germinal epithelium (Choice B) is the outermost layer of the ovary, whereas the medulla is located deeper within the ovary.
3. Ovarian cortex (Choice C) is the outer layer of the ovary where follicles develop, while the medulla is the inner region.
In summary, the correct answer is D (Ovarian medulla) as it accurately identifies the inner region of the ovary where blood vessels and connective tissue are located, distinguishing it from the other choices.
