Section 1: Reproductive Anatomy, Physiology, and Endocrinology (10 Questions)
Q1: A 28-year-old graduate nursing student is reviewing the hypothalamic-pituitary-ovarian (HPO) axis
with a preceptor. During the mid-follicular phase of the menstrual cycle, which hormone is primarily
responsible for the selection and dominance of a single ovarian follicle while simultaneously suppressing
the development of competing follicles?
A. Estrogen, through negative feedback on GnRH pulsatility, suppresses LH surge and prevents follicular
selection.
B. Inhibin B, secreted by granulosa cells, selectively suppresses FSH secretion from the anterior pituitary,
allowing the dominant follicle to continue developing while atretic follicles regress. [CORRECT]
C. Progesterone, rising from the corpus luteum, maintains follicular dominance through positive
feedback on the pituitary.
D. Activin, produced by the dominant follicle, stimulates FSH secretion to promote multi-follicular
development.
Correct Answer: B
Rationale: Inhibin B is produced by granulosa cells of the developing dominant follicle and exerts
selective negative feedback on FSH secretion, creating a relative FSH decline that causes subordinate
follicles to undergo atresia while the dominant follicle continues maturing. ACOG supports this
understanding of follicular selection physiology. The dominant follicle's continued growth is sustained by
its increasing sensitivity to FSH and later LH. This mechanism is foundational for understanding ovulation
induction protocols and PCOS pathophysiology in advanced practice.
Q2: A 35-year-old patient presents with secondary amenorrhea. Laboratory studies reveal low estradiol,
low FSH, and low LH. Which anatomical structure is most likely dysfunctional based on this hormonal
pattern?
,A. Ovaries, indicating primary ovarian insufficiency with elevated gonadotropins.
B. Hypothalamus or pituitary, indicating hypogonadotropic hypogonadism with disrupted GnRH
pulsatility or pituitary failure. [CORRECT]
C. Endometrium, indicating Asherman syndrome with intact ovarian function.
D. Adrenal glands, indicating adrenal hyperplasia with androgen excess.
Correct Answer: B
Rationale: Low estradiol with concurrently low FSH and LH indicates hypogonadotropic hypogonadism,
pointing to a central defect at the hypothalamic or pituitary level rather than primary ovarian failure.
ACOG Practice Bulletin No. 141 recommends evaluating for functional hypothalamic amenorrhea,
pituitary adenomas, or Sheehan syndrome. The APRN must differentiate central from peripheral causes
to guide appropriate imaging (MRI for pituitary) versus ovarian assessment.
Q3: During a pelvic examination workshop, a WHNP student is asked to identify the ligament that
provides the primary support for the uterus and maintains its anteverted position. Which structure
should the student correctly identify?
A. The cardinal ligaments, which primarily prevent uterine prolapse and support the cervix.
B. The round ligaments, which maintain the anteverted position of the uterus by anchoring the fundus
anteriorly. [CORRECT]
C. The uterosacral ligaments, which pull the cervix posteriorly and superiorly toward the sacrum.
D. The broad ligament, which is a peritoneal fold providing passive rather than active uterine support.
Correct Answer: B
Rationale: The round ligaments arise from the lateral aspect of the uterine fundus, pass through the
inguinal canal, and insert into the labia majora, maintaining the uterus in an anteverted and anteflexed
position. ACOG Clinical Consensus No. 13 emphasizes understanding pelvic support anatomy for
diagnosing and managing pelvic organ prolapse. WHNPs must recognize that round ligament pain during
pregnancy and pelvic support defects share anatomical foundations relevant to patient education and
surgical referral decisions.
Q4: A 24-year-old patient asks her WHNP about the physiological changes in cervical mucus during the
menstrual cycle. Which description most accurately reflects the characteristics of estrogen-dominant
cervical mucus at the time of peak fertility?
A. Thick, opaque, and acidic with low spinnbarkeit, creating a barrier to sperm penetration.
B. Thin, clear, watery, and alkaline with high spinnbarkeit and ferning pattern, facilitating sperm
transport and capacitation. [CORRECT]
C. Scant, viscous, and cellular with minimal elasticity, reflecting progesterone dominance.
D. Blood-tinged and purulent, indicating normal ovulatory spotting and cervical inflammation.
, Correct Answer: B
Rationale: Estrogen-stimulated cervical mucus becomes thin, clear, and stretchy (spinnbarkeit) with a
ferning pattern on drying, creating channels that facilitate sperm penetration and transport through the
cervix. ACOG supports this knowledge for fertility awareness-based methods and infertility evaluation.
WHNPs counseling patients on natural family planning must understand these physiological markers to
teach accurate fertility awareness and differentiate normal from pathological cervical discharge.
Q5: A 42-year-old perimenopausal patient reports irregular menstrual cycles. Her FSH is elevated at 35
mIU/mL, estradiol is variable, and inhibin B is low. Which pathophysiological explanation best describes
the hormonal changes driving her clinical presentation?
A. Accelerated follicular depletion reduces inhibin B secretion, removing negative feedback on FSH and
causing erratic FSH elevations that stimulate intermittent follicular development. [CORRECT]
B. Pituitary hyperplasia causes excessive GnRH secretion, leading to sustained FSH elevation and
continuous estrogen production.
C. Ovarian theca cells become hyperresponsive to LH, producing excessive androgens that suppress FSH
and cause anovulation.
D. Endometrial progesterone receptors downregulate, causing unopposed estrogen action and
continuous bleeding.
Correct Answer: A
Rationale: Perimenopause is characterized by accelerated follicular depletion, which reduces inhibin B
production and removes its negative feedback on FSH; the resulting FSH elevation stimulates remaining
follicles erratically, causing variable estrogen levels and irregular cycles. ACOG Practice Bulletin No. 141
describes this as the hallmark endocrine transition to menopause. WHNPs must recognize this pattern
to differentiate normal perimenopause from pathological bleeding requiring endometrial evaluation and
to counsel patients on symptom management.
Q6: A 30-year-old patient with a history of anorexia nervosa presents with amenorrhea. Her BMI is 16.5
kg/m², leptin is low, and kisspeptin neurons show reduced activity. Which mechanism best explains the
disruption of her reproductive endocrine function?
A. Excessive cortisol from chronic stress directly suppresses ovarian steroidogenesis.
B. Low leptin levels signal inadequate energy stores, suppressing hypothalamic kisspeptin neurons and
reducing GnRH pulsatility, leading to hypogonadotropic hypogonadism. [CORRECT]
C. Thyroid dysfunction from malnutrition causes elevated TRH, which stimulates prolactin and
suppresses ovulation.
D. Low estrogen from fat depletion causes positive feedback on the pituitary, increasing FSH and LH.
