1. 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.

2. 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.

3. _______ is a lytic enzyme released by the sperm.

• A. Hyaluronidase
• B. Trypsin
• C. Helicase
• D. None of the above

Correct answer: A

Rationale: Hyaluronidase is the correct answer. It is a lytic enzyme released by the sperm to help penetrate the egg's protective layer. Trypsin is a digestive enzyme produced in the pancreas, not released by sperm. Helicase is an enzyme involved in DNA replication, not released by sperm. 'None of the above' is incorrect as hyaluronidase fits the description provided in the question.

4. During menopause, what do ovaries stop producing?

• A. Progesterone and Estrogen
• B. Prolactin
• C. Human chorionic gonadotropin
• D. Oxytocin

Correct answer: A

Rationale: During menopause, the ovaries stop producing progesterone and estrogen. Progesterone and estrogen are hormones essential for the menstrual cycle and reproductive functions. Prolactin is a hormone responsible for milk production in the breasts and is not primarily produced by the ovaries. Human chorionic gonadotropin (hCG) is produced during pregnancy to support the production of progesterone and estrogen. Oxytocin is a hormone involved in labor and breastfeeding, not primarily produced by the ovaries.

5. At what point is a fetus considered viable?

• A. 26 weeks
• B. 28 weeks
• C. 37 weeks
• D. 12 weeks

Correct answer: C

Rationale: A fetus is considered viable after 37 weeks of gestation. At this stage, the fetus has a higher chance of surviving outside the womb with medical support. Choice A (26 weeks), Choice B (28 weeks), and Choice D (12 weeks) are incorrect because a fetus is not typically considered viable at those earlier gestational ages.
