1. A solid ball of 12-16 cells having undergone mitotic division after fertilization is:

• A. Zygote
• B. Blastomere
• C. Morula
• D. Blastocyst

Correct answer: C

Rationale: A morula is a stage in embryonic development where a solid ball of 12-16 cells is formed after several rounds of mitotic division following fertilization. The zygote is the initial cell formed by the fusion of sperm and egg. Blastomere refers to individual cells in a developing embryo. A blastocyst is a later stage where a fluid-filled cavity forms within the embryo. Therefore, the correct answer is 'Morula.'

2. 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.

3. 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.

4. In which of the following types of spontaneous abortions would the nurse assess dark brown vaginal discharge and a negative pregnancy test?

• A. Threatened
• B. Imminent
• C. Missed
• D. Incomplete

Correct answer: C

Rationale: Dark brown vaginal discharge and a negative pregnancy test are characteristic of a missed abortion. In a missed abortion, the fetus has died, but the products of conception are retained in the uterus. This can lead to symptoms like dark brown vaginal discharge as the body tries to expel the nonviable pregnancy. A threatened abortion is characterized by vaginal bleeding without dilation of the cervix, and the pregnancy remains viable. Imminent abortion involves cervical dilation and effacement with no passage of tissue. In an incomplete abortion, only part of the products of conception are expelled, leading to persistent bleeding and cramping.

5. The upper folds of the labia minora surround the clitoris and unite to form the:

• A. Frenulum
• B. Prepuce
• C. Fourchette
• D. Vestibule

Correct answer: B

Rationale: The correct answer is B: Prepuce. The upper folds of the labia minora surround the clitoris and unite to form the prepuce, which is a hood-like structure protecting the clitoris. The frenulum (choice A) is a small fold of tissue under the tongue or upper lip, not related to the female genitalia. The fourchette (choice C) refers to the area where the labia minora meet at the posterior end of the vulva, not involving the clitoris. The vestibule (choice D) is the space between the labia minora containing the vaginal and urethral openings, not directly formed by the upper folds of the labia minora.
