What keeps the endometrium from shedding if conception occurs?
- A. The anterior pituitary temporarily stops producing luteinizing hormone (LH) and follicle stimulating hormone (FSH).
- B. Human chorionic gonadotropin maintains the corpus luteum, keeping estrogen and progesterone levels high.
- C. None
- D. None
Correct Answer: B
Rationale: hCG maintains the corpus luteum which prevents endometrial shedding.

During a pregnant woman’s second trimester anatomy scan, the fetus was in breech position. The patient is now 34 weeks pregnant and asks how she can tell if the baby is in the right position. What test might be ordered to determine this?
- A. a biophysical profile
- B. an ultrasound
- C. a fetoscopy
- D. a nonstress test
Correct Answer: B
Rationale: An ultrasound can determine the fetus's position. Other tests are not typically used for this purpose.

The nurse is reviewing the hormonal blood work from a patient who is tracking their cycle to try to conceive this month. The patient’s estradiol and progesterone levels are low. What statement would the nurse include in the patient teaching?
- A. “You have already ovulated this month. Let us know if you are not pregnant, and we will try again next month.”
- B. “You should have intercourse tonight and tomorrow. This is the best time to try to conceive.”
- C. “You are at the very beginning of your cycle and will be getting your period very soon.”
- D. “We can’t tell where you are in your cycle from this blood work. You may need to repeat it next week.”
Correct Answer: C
Rationale: Low estradiol and progesterone levels suggest the patient is in the early follicular phase, just before menstruation.

What is the purpose of the ovum’s zona pellucida?
- A. Prevents multiple sperm from fertilizing the ovum
- B. Stimulates the ovum to begin mitotic cell division
- C. Allows the 46 chromosomes from each gamete to merge
- D. Makes a pathway for more than one sperm to reach the ovum
Correct Answer: A
Rationale: The zona pellucida is a protective layer surrounding the ovum (egg cell). One of its primary functions is to prevent multiple sperm from fertilizing the egg by only allowing one sperm to penetrate and fertilize the ovum. This is crucial for ensuring that the resulting embryo has the correct genetic material (46 chromosomes) and does not have an abnormal number of chromosomes, which could lead to developmental issues. The zona pellucida acts as a physical barrier that helps to maintain the genetic integrity of the offspring.
