1. Which of the following is NOT a phase of the menstrual cycle?

• A. Follicular phase
• B. Ovulatory phase
• C. Luteal phase
• D. Secretory phase

Correct answer: D

Rationale: The secretory phase is not considered a distinct phase of the menstrual cycle; it is actually part of the luteal phase. During the luteal phase, the endometrium thickens due to progesterone secretion, preparing for implantation. The follicular phase is characterized by follicle development, leading to ovulation. The ovulatory phase is when the mature egg is released from the ovary. Therefore, the secretory phase is the correct answer as it is not a standalone phase but a part of the luteal phase.

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. 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.

4. What forms the vaginal lining?

• A. Squamous epithelium
• B. Stratified epithelium
• C. Vascular connective tissue
• D. Muscle coat

Correct answer: A

Rationale: The vaginal lining is primarily formed by squamous epithelium. Squamous epithelium is the correct answer because it is the type of epithelium that lines the vaginal canal. Stratified epithelium consists of multiple layers and is not the primary type found in the vaginal lining. Vascular connective tissue and muscle coat are not the main components of the vaginal lining, making them incorrect choices.

5. What is Carboprost used for?

• A. Affects milk production.
• B. Relieve constriction ring.
• C. Management of post-partum haemorrhage.
• D. Induce labor.

Correct answer: C

Rationale: Carboprost is used in the management of post-partum haemorrhage. This medication helps to reduce excessive bleeding after childbirth. Choices A, B, and D are incorrect. Carboprost does not affect milk production, relieve constriction ring, or induce labor.
