The largest ovarian ligament is the _____ ligament.
- A. ovarian
- B. broad
- C. suspensory
- D. sacral
Correct Answer: B
Rationale: The correct answer is B: broad ligament. The broad ligament is the largest ovarian ligament, providing support to the uterus and ovaries. It consists of layers of peritoneum and serves as a protective barrier. The other choices are incorrect because the ovarian ligament specifically connects the ovary to the uterus, the suspensory ligament supports the ovary and contains blood vessels, and the sacral ligament is not related to the ovary.

Which of the following is not involved in parturition.
- A. an increase in prostaglandin secretion
- B. an increase in uterine oxytocin receptors
- C. an increase in luteinising hormone secretion.
- D. an increase in oxytocin secretion.
Correct Answer: C
Rationale: Step-by-step rationale:
1. Parturition is the process of giving birth.
2. Luteinising hormone (LH) is primarily involved in the menstrual cycle and ovulation, not parturition.
3. Prostaglandins and oxytocin play crucial roles in initiating and sustaining labor.
4. An increase in uterine oxytocin receptors is necessary for effective uterine contractions during parturition.
5. Therefore, an increase in luteinising hormone secretion is not involved in parturition.
Summary of incorrect choices:
A: Incorrect - an increase in prostaglandin secretion is involved in parturition.
B: Incorrect - an increase in uterine oxytocin receptors is necessary for parturition.
D: Incorrect - an increase in oxytocin secretion is crucial for initiating labor.
Spermatogenesis:
- A. occurs in several stages;
- B. includes stages of meiosis I;
- C. includes stages of meiosis II;
- D. it is stimulated by the FSH;
Correct Answer: A
Rationale: Correct Answer: A
Rationale: Spermatogenesis is a complex process involving several stages such as mitosis, meiosis, and maturation. It starts with the division of spermatogonia through mitosis, followed by meiosis I and II to form haploid spermatids. These spermatids then undergo maturation to become spermatozoa. Therefore, spermatogenesis occurs in several stages, making choice A the correct answer.
Summary of Incorrect Choices:
B: While spermatogenesis does involve meiosis, it includes both meiosis I and II, not just meiosis I.
C: Spermatogenesis includes both meiosis I and II, not just meiosis II.
D: Spermatogenesis is primarily regulated by hormones such as testosterone and LH, not FSH.
Which patients meet the criteria for Chlamydia screening?
- A. A 40-year-old woman who is sexually active and uses barrier protection consistently
- B. A 15-year-old female woman who is sexually active with one partner
- C. A 22-year-old woman who is sexually active and uses barrier protection inconsistently
- D. A 23-year-old woman who has had four sexual partners in the last 3 months
Correct Answer: C
Rationale: The correct answer is C because the 22-year-old woman who is sexually active and uses barrier protection inconsistently is at higher risk for Chlamydia infection. Inconsistent use of barrier protection increases the likelihood of exposure to the infection. The other choices (A, B, D) do not specifically mention increased risk factors for Chlamydia. Choice A mentions consistent barrier protection, which lowers the risk. Choice B mentions having one partner, which may reduce the risk compared to multiple partners. Choice D mentions having multiple partners, which increases the risk, but it does not mention current risky behavior like inconsistent barrier protection.
Which of the following suggestions should a nurse give breast-feeding mothers to prevent or eliminate mastitis and breast abscess?
- A. Offer the opposite breast at each feeding to their infants.
- B. Minimize frequent nursing of the infants.
- C. Avoid breast-feeding.
- D. Avoid bathing or showering regularly.
Correct Answer: A
Rationale: Alternating breasts during feedings helps prevent blockages and infections.
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.
