1. Which contraceptive option suppresses sperm motility and inhibits the implantation of the blastocyst?

• A. Copper-T
• B. Diaphragm
• C. Contraceptive pills
• D. Condom

Correct answer: A

Rationale: The correct answer is A, Copper-T. Copper-T is an intrauterine device that releases copper ions, which suppress sperm motility and inhibit the implantation of the blastocyst. This method mainly works by preventing fertilization and, if fertilization occurs, by making the endometrium less receptive to implantation. Choices B, C, and D are incorrect. The diaphragm is a barrier method that prevents sperm from reaching the cervix; contraceptive pills mainly work by suppressing ovulation and altering cervical mucus to prevent sperm from reaching the egg; condoms are barrier methods that prevent sperm from entering the vagina.

2. 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.

3. What is the measurement of the breast areola?

• A. 3.5cm
• B. 2.5cm
• C. 4.5cm
• D. 1.5cm

Correct answer: B

Rationale: The correct answer is 2.5 cm. The average measurement of the areola is approximately 2.5 cm. Choices A, C, and D are incorrect as they do not align with the typical measurement of the breast areola.

4. How many autosomes does a human primary spermatocyte have?

• A. 34
• B. 44
• C. 54
• D. 33

Correct answer: B

Rationale: A human primary spermatocyte has 44 autosomes. Autosomes are chromosomes that are not involved in determining an individual's sex. In humans, there are a total of 46 chromosomes in a somatic cell, with 22 pairs of autosomes and one pair of sex chromosomes. Therefore, the correct answer is 44 autosomes, making choice B the correct answer. Choices A, C, and D are incorrect as they do not represent the accurate number of autosomes in a human primary spermatocyte.

5. 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.
