Complete Q&A with Verified Answers & Detailed
Rationales
SECTION I: REPRODUCTIVE ANATOMY & PHYSIOLOGY
1. A nurse is teaching a client about the menstrual cycle. Which
hormone is responsible for ovulation?
A) Estrogen
B) Progesterone
C) Follicle-stimulating hormone (FSH)
D) Luteinizing hormone (LH)
Answer: D) Luteinizing hormone (LH)
Rationale: Luteinizing hormone (LH) surge triggers ovulation, which is
the release of a mature oocyte from the ovarian follicle. FSH stimulates
follicle development and estrogen production. Estrogen promotes
endometrial proliferation, and progesterone prepares the endometrium
for implantation. Understanding the hormonal cascade is essential for
fertility assessment and menstrual cycle education .

2. A nurse is explaining the phases of the menstrual cycle to a client.
Which phase occurs after ovulation and is characterized by
progesterone secretion?
A) Follicular phase
B) Ovulatory phase
C) Luteal phase
D) Menstrual phase
Answer: C) Luteal phase
Rationale: The luteal phase occurs after ovulation, when the ruptured
follicle transforms into the corpus luteum, which secretes progesterone
to prepare the endometrium for implantation. If fertilization does not
occur, the corpus luteum degenerates, progesterone levels fall, and
menstruation begins. The follicular phase occurs before ovulation; the
ovulatory phase is when the egg is released; the menstrual phase is
shedding of the endometrium .
3. A nurse is teaching a client about fertilization. Where does
fertilization typically occur?
A) Ovary
B) Uterus
C) Fallopian tube (ampulla)
D) Cervix
Answer: C) Fallopian tube (ampulla)
Rationale: Fertilization typically occurs in the ampulla (outer third) of
the fallopian tube. The sperm meets the ovum in the fallopian tube, and
the zygote then travels to the uterus for implantation. Implantation
,3|Page
occurs in the endometrium of the uterus. The cervix is the lower part of
the uterus that connects to the vagina .
4. A nurse is assessing a client's knowledge of reproductive anatomy.
Which structure is responsible for producing estrogen and
progesterone during pregnancy?
A) Ovaries
B) Corpus luteum
C) Placenta
D) Pituitary gland
Answer: C) Placenta
Rationale: During pregnancy, the placenta becomes the primary source
of estrogen and progesterone production after the first trimester. Initially,
the corpus luteum produces these hormones to maintain the pregnancy
until the placenta takes over. The ovaries produce hormones in non-
pregnant states, and the pituitary gland produces FSH and LH .
5. A nurse is teaching a client about the changes that occur during
the menstrual cycle. Which hormone is responsible for endometrial
proliferation (thickening)?
A) Estrogen
B) Progesterone
C) LH
D) FSH
Answer: A) Estrogen
, 4|Page
Rationale: Estrogen is responsible for endometrial proliferation
(thickening) during the follicular phase. Progesterone, secreted during
the luteal phase, stabilizes the endometrium and prepares it for
implantation. FSH stimulates follicle development, and LH triggers
ovulation .
6. A nurse is explaining the function of the fallopian tubes to a client.
Which statement about the fallopian tubes is correct?
A) The fallopian tubes produce eggs
B) The fallopian tubes are the site of fertilization
C) The fallopian tubes are where implantation occurs
D) The fallopian tubes produce estrogen
Answer: B) The fallopian tubes are the site of fertilization
Rationale: The fallopian tubes (oviducts) are the site where fertilization
occurs. The ovaries produce eggs (ova). Implantation occurs in the
endometrium of the uterus. The ovaries produce estrogen and
progesterone. The fallopian tubes transport the ovum toward the uterus .
7. A nurse is teaching a client about the corpus luteum. Which
statement by the client indicates understanding?
A) "The corpus luteum forms after the egg is released and produces
progesterone"
B) "The corpus luteum is where the egg is stored before ovulation"
C) "The corpus luteum produces estrogen during the follicular phase"
D) "The corpus luteum is part of the fallopian tube"
Answer: A) "The corpus luteum forms after the egg is released and
produces progesterone"
