1. Causes of metrorrhagia include:

• A. Cervical carcinoma
• B. Uterine polyp
• C. Cervical endometriosis
• D. Infections like Chlamydia

Correct answer: A

Rationale: Metrorrhagia refers to irregular menstrual bleeding that occurs between periods. Cervical carcinoma, a type of cancer that develops in the cervix, can lead to metrorrhagia. Uterine polyps, which are growths attached to the inner wall of the uterus, can also cause abnormal bleeding. While infections like Chlamydia can cause abnormal vaginal bleeding, they are not common causes of metrorrhagia. Cervical endometriosis, although a possible gynecological condition, is not a typical cause of metrorrhagia. Therefore, the correct answer is cervical carcinoma as it is a known cause of metrorrhagia, making the other options incorrect.

2. Which animal is an ovoviviparous animal?

• A. Basking shark
• B. Bonobo
• C. Blue shark
• D. None of the above

Correct answer: C

Rationale: The correct answer is the Blue shark. Ovoviviparous animals produce eggs that develop inside the body of the parent, and the offspring are born alive. The basking shark does not fall under this category as it is ovoviviparous, meaning it lays eggs that hatch inside the female's body. The bonobo is a separate species and not relevant to the question.

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. A woman is considered to be in menopause if she has experienced the cessation of her menses for a period of:

• A. 6 months
• B. 12 months
• C. 18 months
• D. 24 months

Correct answer: B

Rationale: Menopause is defined as the cessation of menses for 12 months. This period is significant because it indicates the end of a woman's reproductive years. Choices A, C, and D are incorrect as they do not align with the established criteria for defining menopause.

5. Each breast is situated on each side of the sternum and extends between the:

• A. 1st and 6th rib
• B. 2nd and 6th rib
• C. 3rd and 6th rib
• D. 4th and 6th rib

Correct answer: B

Rationale: The correct answer is B: 2nd and 6th rib. Each breast is situated between the 2nd and 6th ribs. This anatomical location is important for understanding breast examination techniques and identifying potential abnormalities. Choices A, C, and D are incorrect because the breasts do not extend as far as the 1st, 3rd, or 4th rib, respectively. Understanding the precise anatomical location of structures is crucial in healthcare to ensure accurate assessments and interventions.
