Which of the following hormones promotes endometrial growth?
- A. LH
- B. FSH
- C. Estrogen
- D. Progesterone
Correct Answer: C
Rationale: Estrogen is the hormone responsible for promoting endometrial growth. Estrogen helps thicken the endometrium during the menstrual cycle in preparation for implantation. LH (Choice A) and FSH (Choice B) are involved in regulating the menstrual cycle but do not directly promote endometrial growth. Progesterone (Choice D) is important for maintaining the endometrium after ovulation but is not the primary hormone responsible for promoting its growth.

During an ectopic pregnancy, what is the likelihood of a rupture in the ampullary portion of the tube?
- A. Frequent
- B. Uncommon
- C. Occasional
- D. Never
Correct Answer: A
Rationale: During an ectopic pregnancy, a rupture in the ampullary portion of the tube is frequent. This is due to the increased pressure within the fallopian tube as the embryo grows, leading to the rupture of the tube. Choices B, C, and D are incorrect as they do not accurately describe the common occurrence of rupture in this specific part of the tube during an ectopic pregnancy.
Which of the following are layers of endometrium in pregnancy EXCEPT?
- A. Decidua compacta
- B. Decidua spongiosum
- C. Decidua functionalis
- D. Decidua basalis
Correct Answer: C
Rationale: During pregnancy, the layers of endometrium include decidua compacta, decidua spongiosum, and decidua basalis. Decidua functionalis is the layer that sheds during menstruation and regenerates each cycle, not a layer of the endometrium during pregnancy. Therefore, choice C is the correct answer. Decidua compacta is the layer closest to the conceptus, decidua spongiosum is the middle layer, and decidua basalis is the layer adjacent to the myometrium.
Which of the following are types of induced abortions?
- A. Therapeutic abortion
- B. Missed abortion
- C. Inevitable abortion
- D. Threatened abortion
Correct Answer: A
Rationale: The correct answer is A, therapeutic abortion, which is a type of induced abortion performed for medical reasons. Missed abortion, inevitable abortion, and threatened abortion are types of spontaneous abortions, not induced abortions. Missed abortion refers to a non-viable pregnancy, inevitable abortion is a miscarriage that cannot be stopped, and threatened abortion is when there is bleeding during pregnancy without cervical dilation.
_______ is a lytic enzyme released by the sperm.
- A. Hyaluronidase
- B. Trypsin
- C. Helicase
- D. None of the above
Correct Answer: A
Rationale: Hyaluronidase is the correct answer. It is a lytic enzyme released by the sperm to help penetrate the egg's protective layer. Trypsin is a digestive enzyme produced in the pancreas, not released by sperm. Helicase is an enzyme involved in DNA replication, not released by sperm. 'None of the above' is incorrect as hyaluronidase fits the description provided in the question.
When does threatened abortion occur?
- A. The patient experiences slight vaginal bleeding through an undilated cervix.
- B. The patient experiences heavy bleeding and cervical dilation.
- C. The patient experiences severe cramping and heavy bleeding.
- D. The patient experiences painless bleeding and an open cervix.
Correct Answer: A
Rationale: Threatened abortion occurs when the patient experiences slight vaginal bleeding through an undilated cervix. This is characterized by bleeding without cervical dilation, distinguishing it from inevitable abortion (heavy bleeding and cervical dilation), incomplete abortion (severe cramping and heavy bleeding), and missed abortion (painless bleeding and an open cervix).
