Reproductive System Exam Questions
1. Discuss the anatomical/physiological changes in pregnancy under the following: Cardiovascular system
- A. The heart is displaced upward and to the left by the enlarging uterus, cardiac capacity increases, and blood pressure declines slightly.
- B. The heart is displaced downward and to the right, and blood pressure increases.
- C. The cardiovascular system remains unchanged during pregnancy.
- D. Cardiovascular changes include increased peripheral resistance and reduced cardiac output.
Correct answer: A
Rationale: During pregnancy, the cardiovascular system undergoes changes such as the heart being displaced upward and to the left by the enlarging uterus, increased cardiac capacity, and a slight decline in blood pressure. Choice B is incorrect as the heart is displaced upwards, not downwards, and blood pressure typically decreases slightly. Choice C is incorrect as the cardiovascular system does undergo changes during pregnancy. Choice D is incorrect as cardiovascular changes in pregnancy involve increased cardiac output rather than reduced output.
2. Incomplete abortion is characterized by:
- A. Heavy bleeding.
- B. Open os.
- C. Severe cramping.
- D. Light bleeding.
Correct answer: B
Rationale: Incomplete abortion is characterized by an open os, which means that the cervix is dilated, allowing for passage of tissue. This condition typically presents with heavy bleeding as parts of the products of conception are expelled. Severe cramping may also be present due to uterine contractions. Therefore, the correct characteristic of incomplete abortion is an open os (Choice B). Choices A, C, and D are incorrect as heavy bleeding and severe cramping are symptoms associated with incomplete abortion, but they do not specifically define it, and light bleeding is not characteristic of incomplete abortion.
3. What is the role of relaxin hormone?
- A. Relaxation of the symphysis pubis.
- B. Stimulation of milk production.
- C. Stimulating the development of the nipple and duct system in the breast.
- D. None of the above.
Correct answer: A
Rationale: The correct answer is A: Relaxation of the symphysis pubis. Relaxin hormone is responsible for loosening the ligaments in the pelvic area, particularly the symphysis pubis, to prepare for childbirth. Choice B, stimulation of milk production, is incorrect as this is primarily regulated by prolactin. Choice C, stimulating the development of the nipple and duct system in the breast, is incorrect as this is mainly influenced by estrogen and progesterone during pregnancy. Therefore, the correct role of relaxin hormone is the relaxation of the symphysis pubis.
4. What is the content of the acrosome?
- A. Lipids
- B. Hormones
- C. Digestive enzymes
- D. None of the above
Correct answer: C
Rationale: The correct answer is C: Digestive enzymes. The acrosome is a structure found in sperm cells that contains enzymes used to penetrate the egg during fertilization. Choice A (Lipids) and Choice B (Hormones) are incorrect as the primary content of the acrosome is digestive enzymes, not lipids or hormones. Choice D (None of the above) is incorrect as the acrosome does contain a specific substance, which are digestive enzymes.
5. During menopause, what do ovaries stop producing?
- A. Progesterone and Estrogen
- B. Prolactin
- C. Human chorionic gonadotropin
- D. Oxytocin
Correct answer: A
Rationale: During menopause, the ovaries stop producing progesterone and estrogen. Progesterone and estrogen are hormones essential for the menstrual cycle and reproductive functions. Prolactin is a hormone responsible for milk production in the breasts and is not primarily produced by the ovaries. Human chorionic gonadotropin (hCG) is produced during pregnancy to support the production of progesterone and estrogen. Oxytocin is a hormone involved in labor and breastfeeding, not primarily produced by the ovaries.
