Reproductive Health Exam

1. Which phase of the menstrual cycle is variable?

A. Ovulatory
B. Regenerative
C. Secretory
D. Menstrual

Correct answer: B

Rationale: The regenerative phase of the menstrual cycle is the phase in which the endometrium rebuilds after menstruation. This phase can vary in duration from woman to woman and cycle to cycle. Choice A, the ovulatory phase, is not variable as it typically lasts around 24 hours. Choice C, the secretory phase, is also relatively consistent in its duration. Choice D, the menstrual phase, is the shedding of the endometrial lining and usually lasts around 3-7 days.

2. Which of the following structures is responsible for the production of sperm?

A. Epididymis
B. Seminal vesicles
C. Testes
D. Prostate gland

Correct answer: C

Rationale: The testes are the male reproductive organs responsible for the production of sperm through a process called spermatogenesis. The epididymis is a structure where sperm mature and are stored temporarily. Seminal vesicles produce a significant portion of the fluid that ultimately becomes semen, but they do not produce sperm. The prostate gland contributes additional fluid to semen but does not produce sperm. Therefore, the correct answer is the testes.

3. Which of the following is an example of a viviparous animal?

A. Goat
B. Duck
C. Crocodile
D. None of the above

Correct answer: A

Rationale: The correct answer is A, goat. Viviparous animals give birth to live young ones instead of laying eggs. Ducks and crocodiles are oviparous, meaning they lay eggs, making them incorrect choices. 'None of the above' is incorrect because goats are a valid example of viviparous animals.

4. Which component of reproductive health ensures the provision of quality reproductive health services at all levels of the health care system?

A. Safe motherhood
B. Adolescent health and development
C. Health service delivery
D. Reproductive health information

Correct answer: C

Rationale: Health service delivery is the component of reproductive health that specifically focuses on ensuring the provision of quality reproductive health services at all levels of the healthcare system. While safe motherhood and adolescent health are important aspects of reproductive health, they do not directly address the quality of health services delivery. Reproductive health information, although crucial, is not the component responsible for ensuring the quality of services provided.

5. The patient about to undergo gynecological surgery is put on nil by mouth for ____ before surgery to prevent aspiration.

A. 2-4 hours
B. 3-5 hours
C. 4-6 hours
D. 5-7 hours

Correct answer: C

Rationale: Patients undergoing gynecological surgery are typically advised to be nil by mouth for 4-6 hours before the procedure to reduce the risk of aspiration. This duration allows the stomach to empty its contents, decreasing the likelihood of regurgitation and aspiration of stomach contents during surgery. Choices A, B, and D have shorter durations and may not provide sufficient time for adequate gastric emptying, increasing the risk of aspiration.
