Reproductive System Exam Quizlet

1. 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.

2. In missed abortion, what will the woman often experience?

A. Severe cramping and lower abdominal pains
B. Brownish vaginal discharge
C. Profuse per vagina bleeding
D. Open cervical OS

Correct answer: B

Rationale: In missed abortion, the woman often experiences brownish vaginal discharge. This is known as a symptom of missed abortion. Severe cramping and lower abdominal pains (Choice A) are more characteristic of an incomplete abortion, where not all pregnancy tissue is expelled. Profuse per vagina bleeding (Choice C) is more commonly associated with a complete abortion. Open cervical OS (Choice D) is a physical finding and not a typical symptom reported by the woman in missed abortion.

3. What is the definition of incomplete abortion?

A. Part of the products of conception, especially the fetus, is expelled while the placenta and membranes are retained.
B. All products of conception are expelled, and there is minimal per vaginal bleeding.
C. The cervix is closed, and the products of conception remain in the uterus.
D. The cervix dilates, and the products of conception are expelled.

Correct answer: A

Rationale: Incomplete abortion is defined as part of the products of conception, especially the fetus, being expelled while the placenta and membranes are retained. This is the correct definition, making option A the right choice. Option B is incorrect as it describes a complete abortion. Option C is incorrect because in incomplete abortion, the products of conception are not retained in the uterus, and the cervix may be open. Option D is incorrect as it describes a situation more likely to be seen in an inevitable abortion.

4. The following are delays associated with maternal mortality EXCEPT:

A. Delay in recognizing danger signs
B. Delay in arrival at a health facility
C. Delay in initiating treatment
D. Excessive blood loss

Correct answer: D

Rationale: The correct answer is D. Excessive blood loss is not a delay associated with maternal mortality but rather a direct complication. Delays in recognizing danger signs, arriving at a health facility, and initiating treatment are factors that can contribute to maternal mortality by impeding timely access to necessary care.

5. What does the umbilical cord contain?

A. Pluripotent stem cells
B. Cord blood stem cells
C. Blood stem cells
D. None of the above

Correct answer: B

Rationale: The correct answer is B: Cord blood stem cells. The umbilical cord contains stem cells that are found in cord blood, known as cord blood stem cells. These stem cells have the potential to develop into various types of cells and are used in medical treatments. Pluripotent stem cells are typically found in embryos and have the ability to develop into any type of cell in the body, not specifically in the umbilical cord. Choice C, blood stem cells, is a vague term that does not specifically refer to the stem cells found in the umbilical cord. Choice D is incorrect as the umbilical cord does contain cord blood stem cells.
