Reproductive System Exam Quizlet

1. Which hormone is detected in pregnancy tests?

A. Estrogen
B. Progesterone
C. Luteinizing hormone (LH)
D. Human chorionic gonadotropin (hCG)

Correct answer: D

Rationale: Human chorionic gonadotropin (hCG) is the hormone detected in pregnancy tests. During pregnancy, the placenta produces hCG, which can be detected in the urine or blood to confirm pregnancy. Estrogen and progesterone are also essential hormones in pregnancy but are not typically used for pregnancy tests. Luteinizing hormone (LH) is involved in the menstrual cycle and ovulation, not pregnancy.

2. Which of the following is included in a gynecological examination?

A. Abdominal examination
B. General and systemic examination
C. Obstetric exam
D. Pelvic examination

Correct answer: A

Rationale: Correct! A gynecological examination typically includes an abdominal examination to assess the overall health of the patient. This includes checking for any abnormalities, tenderness, or masses. General and systemic examinations are also important as they provide valuable information about the patient's overall health status. Pelvic examination is another essential component of a gynecological exam to assess the reproductive organs. Obstetric exams, focusing on pregnant women, are not part of routine gynecological examinations.

3. Inevitable abortion occurs when:

A. The ovum dies in utero and the decidua capsularis remains intact.
B. The cervix is open, and the products of conception are about to be expelled.
C. The products of conception are expelled before the 20th week of gestation.
D. The fetus dies and is expelled in the first trimester.

Correct answer: B

Rationale: Inevitable abortion occurs when the cervix is open, and the products of conception are about to be expelled. This is a critical point in the process of spontaneous abortion, indicating that expulsion of the products of conception is imminent. Choice A is incorrect as it describes a missed abortion where the ovum dies but the decidua capsularis remains intact. Choice C is incorrect as it describes an incomplete abortion where the products of conception are expelled before the completion of 20 weeks of gestation. Choice D is incorrect as it describes a missed abortion where the fetus dies and is expelled in the first trimester.

4. Polymenorrhoea is defined as:

A. Menstruation that occurs at an interval less than 35 days
B. Menstruation that occurs at an interval greater than 35 days
C. Menstruation that occurs at an interval less than 21 days
D. Menstruation that occurs at an interval greater than 21 days

Correct answer: C

Rationale: Polymenorrhoea is defined as menstruation that occurs at intervals shorter than 21 days. Choice A is incorrect because it describes menstruation at intervals less than 35 days. Choice B is incorrect as it describes menstruation at intervals greater than 35 days. Choice D is incorrect as it describes menstruation at intervals greater than 21 days.

5. 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.
