Amniotic fluid index of 18 cm in the 3rd trimester is interpreted as:
- A. Hydrops fetalis
- B. Normal amniotic fluid volume
- C. Reduced amniotic fluid volume
- D. Increased amniotic fluid volume
Correct Answer: B
Rationale: The correct answer is B: Normal amniotic fluid volume. An amniotic fluid index of 18 cm in the 3rd trimester is considered within the normal range (5-25 cm). This level indicates adequate amniotic fluid for fetal development and is not indicative of hydrops fetalis (A), reduced amniotic fluid volume (C), or increased amniotic fluid volume (D). It is crucial to monitor amniotic fluid levels as deviations from the normal range can impact fetal well-being.
If a woman's white blood cell count was 20,000 after delivery and increased to 40,000 by the second day, this likely indicates

- C. there is a faster return to pre-pregnancy weight in mothers of formula-fed infants

Shortly before menstruation:
- A. Blood levels of estrogen and progesterone decrease
- B. Blood levels of estrogen and progesterone increase
- C. Blood levels of FSH stabilize
- D. The corpus luteum secretes progesterone
Correct Answer: A
Rationale: Before menstruation, blood levels of estrogen and progesterone decrease, leading to the shedding of the endometrium.
Which hormonal effect is noted during the menstrual cycle?
- A. Luteinizing hormone (LH) and follicle-stimulating hormone (FSH) secretion rise
- C. A negative feedback mechanism is exhibited by the anterior pituitary gland and ovaries.
- D. The posterior pituitary gland secretes LH.
Correct Answer: A
Rationale: The correct answer is A because during the menstrual cycle, LH and FSH secretion rise to stimulate ovarian follicle development and trigger ovulation. This process is crucial for maintaining the menstrual cycle. Choice B is incorrect as it is incomplete. Choice C is incorrect as negative feedback is primarily between the hypothalamus, pituitary gland, and ovaries, not just the anterior pituitary gland and ovaries. Choice D is incorrect because LH is primarily secreted by the anterior pituitary gland, not the posterior pituitary gland.
