Reproductive Health Exam Questions And Answers

1. Where does the ovum receive the sperm?

A. Animal pole
B. Vegetal pole
C. Zona pellucida
D. None of the above

Correct answer: C

Rationale: The correct answer is C, 'Zona pellucida.' The ovum receives the sperm at the zona pellucida, which is the glycoprotein layer surrounding the plasma membrane of the oocyte. This layer plays a crucial role in preventing polyspermy. Choices A and B, 'Animal pole' and 'Vegetal pole,' are incorrect as they refer to different regions of the egg and are not where the sperm fertilizes the ovum. Choice D, 'None of the above,' is incorrect as the sperm indeed interacts with the zona pellucida during fertilization.

2. A menstrual disorder with irregular or continuous bleeding from the uterus is known as:

A. Menorrhagia
B. Metrorrhagia
C. Polymenorrhoea
D. Epimenorrhoea

Correct answer: B

Rationale: Metrorrhagia is the correct term for irregular or continuous bleeding from the uterus. Menorrhagia refers to heavy menstrual bleeding, not necessarily irregular. Polymenorrhoea is characterized by frequent menstrual periods, while Epimenorrhoea is not a recognized medical term related to menstrual disorders.

3. The placenta is developed from which part of the trophoblast?

A. Chorionic Frondosum
B. Anchoring Villi
C. Chorionic Laeve
D. Body Stalk

Correct answer: A

Rationale: The correct answer is A: Chorionic Frondosum. The placenta is developed from the chorionic frondosum part of the trophoblast. This structure gives rise to the fetal part of the placenta. Choices B, C, and D are incorrect. Anchoring Villi are projections from the chorionic plate that attach the placenta to the uterine wall. Chorionic Laeve refers to the smooth chorion that covers the fetal surface of the placenta. The Body Stalk is a structure that connects the early embryo to the trophoblastic pole of the blastocyst.

4. Which department of the Government ministries was given the mandate to pilot a draft population policy?

A. The department of planning and development
B. National census
C. Human rights
D. Central statistics

Correct answer: A

Rationale: The correct answer is A: The department of planning and development. In the extract provided, it explicitly mentions that this department was tasked with piloting the population policy. The other choices are incorrect because the National census is primarily responsible for collecting demographic data, Human rights focus on ensuring and protecting human rights, and Central statistics deal with statistical data collection and analysis, none of which directly align with piloting a population policy.
