1. Which hormone regulates the production of milk after childbirth?

• A. Prolactin
• B. Oxytocin
• C. Estrogen
• D. Progesterone

Correct answer: A

Rationale: The correct answer is Prolactin. Prolactin is the hormone responsible for regulating the production of milk after childbirth. It stimulates the mammary glands in the breasts to produce milk. Oxytocin, on the other hand, is responsible for the ejection of milk from the breasts. Estrogen and progesterone play roles in the menstrual cycle and pregnancy but are not directly involved in milk production. Therefore, choices B, C, and D are incorrect.

2. What is dysmenorrhoea?

• A. Heavy menstruation
• B. Light menstruation
• C. Painful menstruation
• D. Infrequent menstruation

Correct answer: C

Rationale: Dysmenorrhoea is the medical term for painful menstruation. It is characterized by cramp-like abdominal pain that occurs just before or during menstruation. Choice A, heavy menstruation, is referred to as menorrhagia. Choice B, light menstruation, is not a term used to describe a specific menstrual condition. Choice D, infrequent menstruation, is known as oligomenorrhea, not dysmenorrhoea.

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 space is present between the bladder and the uterus?

• A. Vesico-uterine pouch
• B. Pubovesical pouch
• C. Retro-uterine pouch
• D. Recto-uterine pouch

Correct answer: A

Rationale: The correct answer is the vesico-uterine pouch. This space is specifically located between the bladder and the uterus. The pubovesical pouch is incorrect as it refers to the space between the pubic bone and the bladder. The retro-uterine pouch, also known as the pouch of Douglas, is located between the uterus and rectum. The recto-uterine pouch is not a recognized anatomical term, making it an incorrect choice.

5. Amniocentesis, a prenatal diagnostic test used to determine fetal sex, genetic anomalies, and biochemical abnormalities, is based on:

• A. The karyotyping of the amniotic fluid
• B. Chorionic villus sampling
• C. Umbilical cord blood sampling
• D. Ultrasound

Correct answer: A

Rationale: The correct answer is A. Amniocentesis involves the analysis of the fetal cells present in the amniotic fluid, which is extracted from the amniotic sac surrounding the developing fetus. This fluid contains cells shed by the fetus, which can be cultured and analyzed to obtain a karyotype, providing information about the fetal sex, genetic anomalies, and biochemical abnormalities. Choices B, C, and D are incorrect because chorionic villus sampling involves obtaining a sample of the chorionic villi from the placenta, not the amniotic fluid; umbilical cord blood sampling is typically used for other purposes like assessing the baby's blood for infections or genetic disorders; and ultrasound is a diagnostic imaging technique that does not involve the analysis of fetal cells for genetic information.
