Question 1 of 5
Which hormone is responsible for stimulating the growth and development of the ovarian follicles?
Correct Answer: C
Rationale: The correct answer is C: Follicle-stimulating hormone (FSH). FSH stimulates the growth and development of ovarian follicles by promoting the production of estrogen in the ovaries. It helps in the maturation of the follicles and ultimately leads to ovulation. Estrogen (
A) and Progesterone (
B) are hormones produced by the ovaries but do not directly stimulate the growth of ovarian follicles. Luteinizing hormone (LH) (
D) is responsible for triggering ovulation and the formation of the corpus luteum, not for the growth and development of ovarian follicles.
Question 2 of 5
Which of the following hormones is responsible for inducing ovulation?
Correct Answer: D
Rationale: The correct answer is D: Luteinizing hormone (LH). LH surge triggers ovulation by stimulating the release of the mature egg from the ovarian follicle. Estrogen and progesterone play roles in the menstrual cycle but do not directly induce ovulation. FSH is involved in follicular development but not ovulation.
Question 3 of 5
What is the primary hormone responsible for maintaining the endometrium during pregnancy?
Correct Answer: A
Rationale: The correct answer is A: Progesterone. Progesterone is the primary hormone responsible for maintaining the endometrium during pregnancy. It helps to thicken the endometrial lining, ensuring a suitable environment for implantation and supporting the developing embryo. Progesterone also inhibits uterine contractions, preventing premature labor. Estrogen, FSH, and LH do not play a primary role in maintaining the endometrium during pregnancy. Estrogen is involved in the initial thickening of the endometrium, while FSH and LH are primarily responsible for ovulation and follicle development.
Question 4 of 5
Which of the following tests is used to assess fetal lung maturity?
Correct Answer: D
Rationale: The correct answer is D: Lecithin-sphingomyelin (L/S) ratio. This test is used to assess fetal lung maturity by measuring the ratio of two substances found in the amniotic fluid. An L/S ratio greater than 2:1 is indicative of mature fetal lungs. This test is crucial in determining if a baby can breathe adequately after birth. The other choices are incorrect because:
A) Non-stress test monitors fetal heart rate and movements,
B) Biophysical profile assesses fetal well-being, and
C) Amniocentesis is a procedure to collect amniotic fluid for genetic testing.
Question 5 of 5
What is the recommended amount of weight gain during pregnancy for a woman with a normal BMI?
Correct Answer: B
Rationale: The correct answer is B (20-30 pounds). This range is recommended for pregnant women with a normal BMI to support the health of both the mother and the baby. Gaining too little weight can lead to complications like low birth weight, while gaining too much weight increases the risk of gestational diabetes and high blood pressure. The other choices are incorrect because they either fall below or exceed the recommended weight gain range, which can pose risks to the pregnancy. It is crucial for the mother to maintain a healthy weight gain to ensure a safe and successful pregnancy.
