Reproductive System Exam Questions

1. Where does fertilization normally occur?

A. Ampulla
B. Interstitial portion
C. Isthmus
D. Infundibulum

Correct answer: A

Rationale: Fertilization typically occurs in the ampulla of the fallopian tube. The ampulla provides the ideal environment for fertilization due to the presence of cilia that help transport the egg and sperm, as well as the nourishing fluid within this region. The interstitial portion, isthmus, and infundibulum of the fallopian tube are not the primary sites for fertilization. The interstitial portion connects the fallopian tube to the uterine cavity, the isthmus is the narrowest part near the uterus, and the infundibulum is the funnel-shaped end near the ovary, where the egg is captured after ovulation.

2. What is the function of luteinizing hormone?

A. Maintains the corpus luteum
B. Ripens the Graafian follicle
C. Prepares the breasts for lactation
D. Produces regrowth of the endometrium

Correct answer: A

Rationale: Luteinizing hormone is responsible for maintaining the corpus luteum after ovulation. This is crucial for the production of progesterone, which helps prepare the endometrium for implantation and supports early pregnancy. Choices B, C, and D are incorrect: B is the function of follicle-stimulating hormone (FSH) which stimulates the growth of ovarian follicles, C is mainly regulated by prolactin, and D is primarily associated with estrogen and progesterone.

3. In Primary Health care, the concept of accessibility requires that:

A. Patients should be required to accept one service in order to gain access to another type of service.
B. A referral network, including transportation, to higher-level facilities should be coupled to PHC services.
C. Patients' access to services should be contingent on social or cultural backgrounds, age, and marital status.
D. Patients' access to services should be based on one's educational status.

Correct answer: B

Rationale: In Primary Health care, accessibility entails having a referral network and transportation system in place to link patients to higher-level facilities when needed. Choice A is incorrect because patients should not be required to accept one service to access another. Choice C is incorrect as access to services should not be contingent on social or cultural backgrounds, age, or marital status. Choice D is also incorrect because educational status should not determine patients' access to healthcare services.

4. What is the purpose of Hysterosalpingo-contrast Sonography?

A. Check a woman's tubes and is done with an X-ray and dye test called a hysterosalpingogram
B. Detect Human Chorionic Gonadotrophic hormone (HCG) in urine or whole blood.
C. Diagnose ovarian cancer using MRI technology.
D. Detect cancer cells in the cervix.

Correct answer: A

Rationale: Hysterosalpingo-contrast Sonography is a test used to check a woman's fallopian tubes with an X-ray and dye test called a hysterosalpingogram. This test is specifically designed to evaluate the patency of the fallopian tubes and the uterine cavity. Choices B, C, and D are incorrect as they do not align with the purpose of Hysterosalpingo-contrast Sonography.

5. Which hormone is primarily responsible for the development of female secondary sexual characteristics?

A. Progesterone
B. Testosterone
C. Estrogen
D. Oxytocin

Correct answer: C

Rationale: Estrogen is primarily responsible for the development of female secondary sexual characteristics. Progesterone, while important in the menstrual cycle and pregnancy, is not primarily responsible for secondary sexual characteristics. Testosterone is the primary male sex hormone. Oxytocin is involved in labor, lactation, and social bonding, but not in the development of female secondary sexual characteristics.
