Reproductive Health Exam Questions And Answers

1. What type of epithelium lines the vagina?

A. Ciliated epithelium.
B. Squamous epithelium.
C. Columnar epithelium.
D. Transitional epithelium.

Correct answer: B

Rationale: The correct answer is B: Squamous epithelium. The vagina is lined with non-keratinized stratified squamous epithelium. This type of epithelium provides protection against abrasion and pathogens. Choice A, Ciliated epithelium, is incorrect as ciliated epithelium is found in areas like the fallopian tubes to help move the egg towards the uterus. Choice C, Columnar epithelium, is incorrect as columnar epithelium is typically found in areas like the intestines. Choice D, Transitional epithelium, is incorrect as this type of epithelium is found in areas like the urinary bladder.

2. Which technique is used to detect HIV/AIDS?

A. Northern blot and ELISA
B. Immunoblot and ELISA
C. Western blot and ELISA
D. Southern blot and ELISA

Correct answer: C

Rationale: The correct answer is C: Western blot and ELISA. Western blot and ELISA are commonly used techniques in the detection of HIV/AIDS. Western blot is used to confirm the presence of HIV antibodies in a patient's blood after an initial positive ELISA test. Northern blotting is a technique used for RNA analysis, not for detecting HIV/AIDS (Choice A). Immunoblotting is another term for Western blotting, so Choice B is incorrect. Southern blotting is used for DNA analysis, not for detecting HIV/AIDS (Choice D).

3. Discuss the anatomical/physiological changes in pregnancy under the following: Uterus

A. The uterus softens in the anterior midline, becomes flexible at the uterocervical junction, blood vasculature increases in size and number, and hypertrophy of myometrial cells occurs.
B. The uterus decreases in size during pregnancy and remains rigid.
C. The uterus size remains unchanged, and no changes occur in the blood vasculature.
D. Uterus becomes more rigid and hypertrophies.

Correct answer: A

Rationale: During pregnancy, the uterus undergoes various anatomical and physiological changes. The correct answer, Choice A, accurately describes these changes. The uterus softens in the anterior midline, becomes flexible at the uterocervical junction, experiences an increase in blood vasculature size and number, and myometrial cells hypertrophy. This softening and increased vascularity are essential for accommodating the growing fetus and facilitating delivery. Choices B, C, and D are incorrect because they do not reflect the typical changes that occur in the uterus during pregnancy. The uterus does not decrease in size, remain unchanged in size, become more rigid, or hypertrophy without the described softening and vascular changes.

4. Which of the following are outcomes of an ectopic pregnancy EXCEPT?

A. Tubal abortion
B. Tubal rupture
C. Intra-tubal bleeding
D. Secondary abdominal pregnancy

Correct answer: D

Rationale: Ectopic pregnancy occurs when a fertilized egg implants outside the uterus. Common outcomes include tubal abortion (spontaneous termination of ectopic pregnancy within the fallopian tube), tubal rupture (rupture of the fallopian tube leading to internal bleeding), and intra-tubal bleeding. Secondary abdominal pregnancy, on the other hand, is a rare occurrence and not a typical outcome of an ectopic pregnancy. It involves the implantation of a fertilized egg in the peritoneal cavity rather than the uterus.

5. A menstrual disorder with irregular or continuous bleeding from the uterus is known as:

A. Menorrhagia
B. Metrorrhagia
C. Polymenorrhoea
D. Epimenorrhoea

Correct answer: B

Rationale: Metrorrhagia is the correct term for irregular or continuous bleeding from the uterus. Menorrhagia refers to heavy menstrual bleeding, not necessarily irregular. Polymenorrhoea is characterized by frequent menstrual periods, while Epimenorrhoea is not a recognized medical term related to menstrual disorders.
