At what point is a fetus considered viable?
- A. 26 weeks
- B. 28 weeks
- C. 37 weeks
- D. 12 weeks
Correct Answer: C
Rationale: A fetus is considered viable after 37 weeks of gestation. At this stage, the fetus has a higher chance of surviving outside the womb with medical support. Choice A (26 weeks), Choice B (28 weeks), and Choice D (12 weeks) are incorrect because a fetus is not typically considered viable at those earlier gestational ages.

What forms the vaginal lining?
- A. Squamous epithelium
- B. Stratified epithelium
- C. Vascular connective tissue
- D. Muscle coat
Correct Answer: A
Rationale: The vaginal lining is primarily formed by squamous epithelium. Squamous epithelium is the correct answer because it is the type of epithelium that lines the vaginal canal. Stratified epithelium consists of multiple layers and is not the primary type found in the vaginal lining. Vascular connective tissue and muscle coat are not the main components of the vaginal lining, making them incorrect choices.
What is one of the roles of the oxytocin hormone?
- A. Stimulates milk ejection.
- B. Stimulates the production of milk.
- C. Stimulates the development of lactoferrin.
- D. Stimulates the secretion of relaxin.
Correct Answer: A
Rationale: The correct answer is A: 'Stimulates milk ejection.' Oxytocin is responsible for contracting the muscles around the milk ducts, pushing milk into the nipples for breastfeeding. This process is known as milk ejection or let-down. The other choices are incorrect because oxytocin's primary function is to facilitate milk ejection rather than directly stimulating the production of milk, the development of lactoferrin, or the secretion of relaxin.

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.
Which of the following data should not be included in the identification data of gynecological history?
- A. Parity
- B. Lost normal menstrual period
- C. EDD (Expected date of delivery)
- D. Last delivery
Correct Answer: C
Rationale: The correct answer is C: EDD (Expected date of delivery). In a gynecological history, EDD is not typically included as it pertains more to obstetric history. Parity, lost normal menstrual period, and last delivery are important components of gynecological history. Parity refers to the number of times a woman has given birth to a fetus past 20 weeks' gestation. Lost normal menstrual period can provide insight into potential gynecological issues, while last delivery details the most recent childbirth experience. Therefore, EDD is the outlier in this context.
