1. 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.

2. Amniocentesis, a prenatal diagnostic test used to determine fetal sex, genetic anomalies, and biochemical abnormalities, is based on:

• A. The karyotyping of the amniotic fluid
• B. Chorionic villus sampling
• C. Umbilical cord blood sampling
• D. Ultrasound

Correct answer: A

Rationale: The correct answer is A. Amniocentesis involves the analysis of the fetal cells present in the amniotic fluid, which is extracted from the amniotic sac surrounding the developing fetus. This fluid contains cells shed by the fetus, which can be cultured and analyzed to obtain a karyotype, providing information about the fetal sex, genetic anomalies, and biochemical abnormalities. Choices B, C, and D are incorrect because chorionic villus sampling involves obtaining a sample of the chorionic villi from the placenta, not the amniotic fluid; umbilical cord blood sampling is typically used for other purposes like assessing the baby's blood for infections or genetic disorders; and ultrasound is a diagnostic imaging technique that does not involve the analysis of fetal cells for genetic information.

3. Cryptorchidism is a condition where _________.

• A. One or both testes are not developed
• B. One or both testes fail to descend into the scrotum
• C. One or both testes are not formed
• D. None of the above

Correct answer: B

Rationale: Cryptorchidism is a condition where one or both testes fail to descend into the scrotum. This means that the testes do not properly move from the abdomen into the scrotum during fetal development. Choice A is incorrect because the issue is not about development but descent. Choice C is incorrect as it implies that the testes were never formed, which is not the case in cryptorchidism. Choice D is incorrect as cryptorchidism does involve the testes but rather their descent into the scrotum.

4. During the menstrual cycle, which hormone maintains the corpus luteum?

• A. Luteinizing hormone
• B. Follicle-stimulating hormone
• C. Progesterone
• D. Relaxin

Correct answer: A

Rationale: During the menstrual cycle, luteinizing hormone maintains the corpus luteum. The correct answer is A. Luteinizing hormone stimulates the corpus luteum to produce progesterone. Choice B, Follicle-stimulating hormone, is involved in stimulating the growth of follicles in the ovaries. Choice C, Progesterone, is produced by the corpus luteum and plays a role in preparing the endometrium for implantation. Choice D, Relaxin, is involved in processes such as softening the cervix and ligaments during pregnancy, but it is not responsible for maintaining the corpus luteum.

5. The products of conception are retained in which of the following?

• A. Complete abortions
• B. Incomplete abortions
• C. Threatened abortion
• D. Mixed abortion

Correct answer: B

Rationale: In incomplete abortions, the products of conception are retained. In a complete abortion, all the products of conception are expelled from the uterus. Threatened abortion refers to a situation where there is vaginal bleeding but the cervix remains closed, and it does not necessarily involve retention of products of conception. Mixed abortion is not a recognized medical term related to retained products of conception.
