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.

Which hormone regulates the production of milk after childbirth?
- A. Prolactin
- B. Oxytocin
- C. Estrogen
- D. Progesterone
Correct Answer: A
Rationale: The correct answer is Prolactin. Prolactin is the hormone responsible for regulating the production of milk after childbirth. It stimulates the mammary glands in the breasts to produce milk. Oxytocin, on the other hand, is responsible for the ejection of milk from the breasts. Estrogen and progesterone play roles in the menstrual cycle and pregnancy but are not directly involved in milk production. Therefore, choices B, C, and D are incorrect.
Which of the following hormone ratios is MOST likely to be increased in a patient with PCOS?
- A. Progesterone/estrogen
- B. LH/FSH
- C. FSH/LH
- D. Glucagon/insulin
Correct Answer: B
Rationale: In patients with Polycystic Ovary Syndrome (PCOS), the LH/FSH ratio is most likely to be increased. This hormonal imbalance is a key characteristic of PCOS, where elevated LH levels relative to FSH contribute to the pathophysiology of the condition. Choice A, progesterone/estrogen ratio, is not typically a defining feature of PCOS. Choice C, FSH/LH ratio, is the reverse of what is commonly observed in PCOS. Choice D, glucagon/insulin ratio, is not directly related to the hormonal imbalances seen in PCOS.
What is the most common cause of abortion in Zambia?
- A. Tuberculosis
- B. HIV
- C. Ascariasis
- D. Malaria
Correct Answer: D
Rationale: Malaria is the most common cause of abortion in Zambia due to its significant impact on maternal health. Malaria can lead to severe complications during pregnancy, increasing the risk of spontaneous abortion. Tuberculosis (Choice A), HIV (Choice B), and Ascariasis (Choice C) are serious health conditions, but they are not typically identified as the primary cause of abortion in Zambia as malaria.
Discuss the anatomical/physiological changes in pregnancy under the following: Cardiovascular system
- A. The heart is displaced upward and to the left by the enlarging uterus, cardiac capacity increases, and blood pressure declines slightly.
- B. The heart is displaced downward and to the right, and blood pressure increases.
- C. The cardiovascular system remains unchanged during pregnancy.
- D. Cardiovascular changes include increased peripheral resistance and reduced cardiac output.
Correct Answer: A
Rationale: During pregnancy, the cardiovascular system undergoes changes such as the heart being displaced upward and to the left by the enlarging uterus, increased cardiac capacity, and a slight decline in blood pressure. Choice B is incorrect as the heart is displaced upwards, not downwards, and blood pressure typically decreases slightly. Choice C is incorrect as the cardiovascular system does undergo changes during pregnancy. Choice D is incorrect as cardiovascular changes in pregnancy involve increased cardiac output rather than reduced output.
What are the Carunculae Myrtiformes?
- A. Tissues between the vagina and the perineum
- B. A component of the clitoral prepuce
- C. The remnants of the torn hymen
- D. Structures that partially close the vaginal introitus
Correct Answer: C
Rationale: The Carunculae Myrtiformes are the remnants of the torn hymen. They are not tissues between the vagina and the perineum (Choice A), a part of the clitoral prepuce (Choice B), or structures that partially close the vaginal introitus (Choice D). Understanding the anatomy of the female reproductive system is crucial for healthcare professionals to provide accurate care and information.
