NUR 230 MATERNAL EXAM 1 PREP 2026 QUESTIONS WITH VERIFIED
ANSWERS DETAILED RATIONALES GRADED A+
Part I: Reproductive Anatomy & Physiology (Questions 1–25)
1. A nurse is teaching a class about female reproductive anatomy. Which structure
is primarily responsible for the production of estrogen and progesterone?
A. Fallopian tubes
B. Ovaries
C. Uterus
D. Cervix
Rationale: The ovaries are the primary female reproductive organs responsible for
producing estrogen and progesterone, which regulate the menstrual cycle,
pregnancy, and secondary sex characteristics. The fallopian tubes transport the
ovum, the uterus is the site of implantation, and the cervix is the lower portion of
the uterus.
2. The nurse is assessing a patient's menstrual history. Ovulation typically occurs
on which day of a 28-day menstrual cycle?
A. Day 7
B. Day 10
C. Day 14
D. Day 21
1|Page
,Page 2 of 75
Rationale: Ovulation typically occurs on day 14 of a 28-day menstrual cycle,
approximately 14 days before the next menstrual period. The surge of luteinizing
hormone (LH) from the anterior pituitary triggers ovulation.
3. The hormone responsible for the "let-down" reflex during breastfeeding is
which of the following?
A. Prolactin
B. Estrogen
C. Oxytocin
D. Progesterone
Rationale: Oxytocin is responsible for the milk ejection reflex (let-down). It is
released from the posterior pituitary in response to nipple stimulation and causes
contraction of the myoepithelial cells surrounding the alveoli in the breast.
4. Which hormone is primarily responsible for stimulating milk production in the
breast?
A. Prolactin
B. Oxytocin
C. Estrogen
D. Progesterone
Rationale: Prolactin, secreted by the anterior pituitary, stimulates the alveoli in
the breasts to produce milk. Oxytocin is responsible for milk ejection, not
production.
5. A nurse is explaining the phases of the ovarian cycle. During which phase does
the corpus luteum form?
A. Follicular phase
B. Luteal phase
C. Ovulatory phase
D. Menstrual phase
2|Page
,Page 3 of 75
Rationale: After ovulation, the ruptured follicle transforms into the corpus luteum
during the luteal phase. The corpus luteum secretes progesterone to prepare the
endometrium for potential implantation.
6. The layer of the uterus that is shed during menstruation is the:
A. Myometrium
B. Perimetrium
C. Endometrium
D. Serosa
Rationale: The endometrium is the inner lining of the uterus that thickens each
cycle and is shed during menstruation if implantation does not occur.
7. Which structure connects the fetal side of the placenta to the fetus?
A. Fallopian tube
B. Umbilical cord
C. Cervix
D. Vagina
Rationale: The umbilical cord connects the fetus to the placenta, containing two
arteries and one vein that facilitate nutrient and gas exchange.
8. A nurse is reviewing the function of the fallopian tubes. What is the primary
role of these structures?
A. Produce estrogen
B. Transport the ovum to the uterus
C. Serve as the site of implantation
D. Produce progesterone
Rationale: The fallopian tubes transport the ovum from the ovary to the uterus
and are the typical site of fertilization. The uterus is the site of implantation.
9. Which of the following is a primary function of the placenta?
A. Production of red blood cells
B. Exchange of nutrients, gases, and waste products
3|Page
, Page 4 of 75
C. Regulation of maternal blood pressure
D. Synthesis of vitamin D
Rationale: The placenta serves as the interface for exchange of nutrients, oxygen,
carbon dioxide, and waste products between the maternal and fetal circulations.
10. The nurse is teaching about the male reproductive system. Which structure is
responsible for sperm production?
A. Prostate gland
B. Testes
C. Epididymis
D. Vas deferens
Rationale: The testes are the primary male reproductive organs responsible for
spermatogenesis (sperm production) and testosterone secretion.
11. Which hormone is primarily responsible for the development of secondary
sexual characteristics in females?
A. Progesterone
B. Estrogen
C. Prolactin
D. Oxytocin
Rationale: Estrogen is responsible for the development of female secondary
sexual characteristics, including breast development and body fat distribution.
12. A nurse is discussing the menstrual cycle with a patient. What is the role of
follicle-stimulating hormone (FSH)?
A. Triggers ovulation
B. Stimulates follicle maturation in the ovary
C. Maintains the corpus luteum
D. Inhibits estrogen production
Rationale: FSH, released by the anterior pituitary, stimulates the growth and
maturation of ovarian follicles. LH triggers ovulation.
