Amniocentesis deals with patterns of ______ in the amniotic fluid.
- A. Fingers
- B. DNA
- C. Chromosomes
- D. Proteins
Correct Answer: C
Rationale: Amniocentesis is a prenatal test that involves examining chromosomes in the amniotic fluid to detect genetic abnormalities. Therefore, the correct answer is 'Chromosomes.' The other choices, such as 'Fingers,' 'DNA,' and 'Proteins,' do not accurately represent what is analyzed during an amniocentesis procedure and are unrelated to the genetic information obtained through this test.

What is the area of the uterus where the fallopian tubes are inserted known as?
- A. Fundus
- B. Corpus or body
- C. Cavity
- D. Cornua
Correct Answer: D
Rationale: The correct answer is D, Cornua. The cornua refers to the upper, horn-like parts of the uterus where the fallopian tubes are inserted. The fundus (choice A) is the rounded top portion of the uterus, the corpus or body (choice B) is the main part of the uterus excluding the cervix and fundus, and the cavity (choice C) refers to the internal space within the uterus. Therefore, choices A, B, and C are incorrect as they do not specifically denote the area where the fallopian tubes are inserted.
What term is used to refer to the fertilized ovum?
- A. Zygote
- B. Embryo
- C. Foetus
- D. Pregnancy
Correct Answer: A
Rationale: The correct answer is A, Zygote. A zygote is formed when a sperm cell fertilizes an egg cell. It is the initial stage of prenatal development. Choice B, Embryo, refers to the stage of prenatal development after the zygote and before the foetus. Choice C, Foetus, is the stage of prenatal development after the embryo. Choice D, Pregnancy, is a broader term referring to the condition of having a developing baby in the uterus.
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.
When does missed abortion occur?
- A. The fetus dies and is retained in utero with the placenta and membranes.
- B. All products of conception are expelled with minimal bleeding.
- C. The cervix remains closed, and the products of conception remain in the uterus.
- D. The cervix remains closed, but there is heavy bleeding.

What is the estimated percentage of deaths due to unsafe abortions from 591 maternal deaths per 100,000 live births?
- A. 0.1
- B. 0.2
- C. 0.3
- D. 0.4
Correct Answer: D
Rationale: To calculate the estimated percentage of deaths due to unsafe abortions, you divide the number of deaths due to unsafe abortions by the total number of maternal deaths and then multiply by 100 to get the percentage. In this case, with 591 maternal deaths and 40% estimated to be due to unsafe abortions, the calculation is (591 * 0.4) / 100, which equals 2.36. Therefore, the estimated percentage of deaths due to unsafe abortions from 591 maternal deaths per 100,000 live births is 0.4 or 40%. Choices A, B, and C are incorrect percentages that do not reflect the provided information.
