Reproductive System Exam Quizlet

1. The endometrium is shed up to the basal layer during this phase of the menstrual cycle:

A. Ovulation
B. Regenerative
C. Secretory
D. Menstruation

Correct answer: D

Rationale: The correct answer is D. During the menstrual phase of the menstrual cycle, the endometrium is shed up to the basal layer. This shedding occurs as a result of decreased levels of estrogen and progesterone, leading to the breakdown and subsequent shedding of the endometrial lining. Choice A, ovulation, is incorrect as ovulation is the release of an egg from the ovary, which occurs during the mid-cycle. Choice B, regenerative, is incorrect as it does not specifically refer to the phase where the shedding of the endometrium occurs. Choice C, secretory, is incorrect as it refers to the phase where the endometrium thickens in preparation for possible implantation of a fertilized egg, not shedding.

2. What does MTP stand for?

A. Medical Termination of Parturition
B. Mechanical Transfer of Pollen
C. Medical Termination of Pregnancy
D. Maternally Transmitted Pathogens

Correct answer: C

Rationale: The correct expansion for MTP is Medical Termination of Pregnancy. This term is commonly used in healthcare to refer to the procedure of ending a pregnancy. Choices A, B, and D are incorrect because they do not accurately represent the expansion of the abbreviation MTP. Choice A refers to labor induction, choice B is related to plant reproduction, and choice D deals with the transmission of pathogens from mother to offspring.

3. Which phase of the menstrual cycle is variable?

A. Ovulatory
B. Regenerative
C. Secretory
D. Menstrual

Correct answer: B

Rationale: The regenerative phase of the menstrual cycle is the phase in which the endometrium rebuilds after menstruation. This phase can vary in duration from woman to woman and cycle to cycle. Choice A, the ovulatory phase, is not variable as it typically lasts around 24 hours. Choice C, the secretory phase, is also relatively consistent in its duration. Choice D, the menstrual phase, is the shedding of the endometrial lining and usually lasts around 3-7 days.

4. In which part of the fallopian tube is tubal abortion most common?

A. Ampullary portion
B. Isthmus
C. Interstitial portion
D. Infundibulum

Correct answer: C

Rationale: Tubal abortion is most common when the ovum implants in the interstitial portion of the fallopian tube. This location is the narrowest part of the tube, making it more prone to obstruction or difficulty in the passage of the fertilized ovum. Choices A, B, and D are incorrect because tubal abortion is more likely to occur in the interstitial portion rather than the ampullary portion, isthmus, or infundibulum of the fallopian tube.

5. 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.
