1. At what age does the first menstrual period typically occur?

• A. 9 and 15 years
• B. 2 and 10 years
• C. 1 and 5 years
• D. 18 and 20 years

Correct answer: A

Rationale: The first menstrual period, known as menarche, typically occurs between the ages of 9 and 15 years. This marks the onset of puberty in females. Choices B, C, and D are incorrect because the first menstrual period does not occur as early as 2 years old, 1 year old, or as late as 18 to 20 years old.

2. Which of the following are types of induced abortions?

• A. Therapeutic abortion
• B. Missed abortion
• C. Inevitable abortion
• D. Threatened abortion

Correct answer: A

Rationale: The correct answer is A, therapeutic abortion, which is a type of induced abortion performed for medical reasons. Missed abortion, inevitable abortion, and threatened abortion are types of spontaneous abortions, not induced abortions. Missed abortion refers to a non-viable pregnancy, inevitable abortion is a miscarriage that cannot be stopped, and threatened abortion is when there is bleeding during pregnancy without cervical dilation.

3. What type of epithelium lines the fallopian tubes?

• A. Ciliated epithelium.
• B. Stratified epithelium.
• C. Columnar epithelium.
• D. Endometrium.

Correct answer: A

Rationale: The correct answer is A: Ciliated epithelium. The fallopian tubes are lined with ciliated epithelium, which helps to move the egg from the ovary to the uterus. Choice B, Stratified epithelium, is incorrect because the fallopian tubes are lined with a single layer of cells. Choice C, Columnar epithelium, is incorrect as it does not accurately describe the lining of the fallopian tubes. Choice D, Endometrium, is incorrect because the endometrium is the inner lining of the uterus, not the fallopian tubes.

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. Which one is not a barrier method for birth control?

• A. Diaphragms
• B. Cervical caps
• C. Vaults
• D. Intrauterine Devices (IUDs)

Correct answer: D

Rationale: The correct answer is D, Intrauterine Devices (IUDs). Barrier methods of birth control physically block sperm from reaching the egg. Diaphragms, cervical caps, and vaults are examples of barrier methods as they create a barrier that prevents sperm from reaching the cervix. In contrast, IUDs work by altering the cervical mucus and uterine lining, making it difficult for sperm to reach the egg, but they do not physically block sperm like barrier methods do.
