1. Which of the following is not a barrier method of birth control?

• A. Vaults
• B. Diaphragms
• C. Sterilization
• D. Cervical caps

Correct answer: C

Rationale: The correct answer is C, Sterilization. Sterilization is a permanent form of birth control that involves surgical procedures to prevent pregnancy by blocking the fallopian tubes or vas deferens. Barrier methods physically prevent sperm from reaching the egg, such as vaults, diaphragms, and cervical caps. These devices create a barrier to sperm, unlike sterilization. Therefore, choices A, B, and D are all considered barrier methods of birth control.

2. _______ 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.

3. During which phase of the menstrual cycle does the Graafian follicle rupture?

• A. Regenerative
• B. Menstruation
• C. Ovulation
• D. Proliferative

Correct answer: C

Rationale: The correct answer is C: Ovulation. The Graafian follicle ruptures during the ovulation phase, releasing the mature egg from the ovary. This process marks the midpoint of the menstrual cycle. Choice A, Regenerative, is incorrect as it does not correspond to a specific phase of the menstrual cycle. Choice B, Menstruation, is incorrect because menstruation is the shedding of the uterine lining and occurs after ovulation if fertilization does not occur. Choice D, Proliferative, is incorrect as it refers to the phase in which the uterine lining thickens in preparation for a potential embryo implantation, which happens after ovulation.

4. In which part of the fallopian tube is tubal abortion most common?

• A. Ampullary portion
• B. Isthmus
• C. Interstitial portion
• D. Infundibulum

Correct answer: C

Rationale: Tubal abortion is most common when the ovum implants in the interstitial portion of the fallopian tube. This location is the narrowest part of the tube, making it more prone to obstruction or difficulty in the passage of the fertilized ovum. Choices A, B, and D are incorrect because tubal abortion is more likely to occur in the interstitial portion rather than the ampullary portion, isthmus, or infundibulum of the fallopian tube.

5. What is the most common symptom in all clinical types of abortion EXCEPT:

• A. Lower abdominal pain
• B. Per vaginal bleeding
• C. Show
• D. Backache

Correct answer: C

Rationale: The correct answer is C. 'Show' is not a common symptom in all types of abortion. Lower abdominal pain, per vaginal bleeding, and backache are common symptoms associated with abortion. Lower abdominal pain may result from uterine contractions, per vaginal bleeding is a typical presentation, and backache can be a symptom due to the process of abortion. 'Show' refers to the mucus plug that blocks the cervix during pregnancy and is not a typical symptom of abortion.
