1. What is the typical measurement of the anterior wall of the vaginal canal?

• A. 10 cm
• B. 11 cm
• C. 11.5 cm
• D. 7.5 cm

Correct answer: D

Rationale: The typical measurement of the anterior wall of the vaginal canal is 7.5 cm. This measurement is anatomically accurate, making choice D the correct answer. Choices A, B, and C provide measurements that are larger than the typical measurement of the anterior wall of the vaginal canal and are therefore incorrect.

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. How do contraceptive oral pills help in birth control?

• A. Preventing ovulation
• B. Killing ova
• C. Killing sperms
• D. More than one of the above

Correct answer: A

Rationale: Contraceptive oral pills primarily work by preventing ovulation, which means Choice A is correct. Choices B and C are incorrect because oral contraceptive pills do not kill ova or sperms. Choice D is incorrect because only preventing ovulation is the primary mechanism of action for oral contraceptive pills.

4. _______ 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.

5. What is one goal of family planning?

• A. Ensuring that all couples and individuals have the basic right to decide freely and responsibly the number and spacing of their children
• B. Limiting couples and individuals to one or two children
• C. Forcing couples and individuals to have only one child and adopt siblings from an orphanage
• D. Providing a permanent method of family planning after having three children

Correct answer: A

Rationale: The correct answer is A. Family planning aims to ensure that all couples and individuals have the basic right to decide freely and responsibly the number and spacing of their children. This promotes reproductive autonomy and allows individuals to make informed choices about their family size. Choices B, C, and D are incorrect because they involve imposing restrictions or decisions on family size rather than empowering individuals to make their own choices.
