WALDEN UNIVERSITY NURS 6551 OB MIDTERM EXAM (LATEST
UPDATE): 200 COMPREHENSIVE EXAM QUESTIONS AND EVIDENCE-
BASED RATIONALES ON BREAST DISORDERS, GYNECOLOGIC PAIN, HIV
TESTING PROTOCOLS, MENSTRUAL DYSFUNCTION, CONTRACEPTION,
AND VAGINAL INFECTIONS
1. Which of the following is the most common cause of cyclic
mastalgia?
A. Fibrocystic breast changes
B. Hormonal fluctuations associated with the menstrual cycle
C. Excessive caffeine intake
D. Ill-fitting brassieres
Correct Answer: B
Rationale: Cyclic mastalgia is primarily driven by the hormonal changes
(estrogen and progesterone) that occur during the menstrual cycle,
leading to breast tissue proliferation and pain.
2. When evaluating a patient with mastalgia, which clinical finding is
most concerning for underlying malignancy?
A. Bilateral, diffuse breast tenderness
B. Pain that resolves after menstruation
C. Unilateral, fixed palpable mass with skin dimpling
D. Sharp, burning pain in the upper outer quadrant
Correct Answer: C
Rationale: While most mastalgia is benign, a fixed, palpable mass
accompanied by skin changes (like dimpling or nipple retraction) is a
,classic warning sign for breast cancer and requires immediate
diagnostic imaging.
3. A 42-year-old female presents with heavy, painful periods and an
enlarged, tender uterus. Which condition is most likely frequently
underdiagnosed due to its symptom overlap with other pelvic pain
conditions?
A. Endometriosis
B. Uterine fibroids
C. Adenomyosis
D. Pelvic inflammatory disease
Correct Answer: C
Rationale: Adenomyosis frequently presents with dysmenorrhea and
menorrhagia, which mimic other common pelvic pain conditions like
endometriosis or fibroids, leading to frequent underdiagnosis until
imaging (MRI/ultrasound) or histology confirms it.
4. According to the 2006 CDC recommendations for HIV testing in
healthcare settings, what is the standard protocol?
A. Test only patients who report high-risk behaviors
B. Test all patients unless they explicitly decline to be tested (opt-out)
C. Require written informed consent before testing
D. Test only pregnant women and intravenous drug users
Correct Answer: B
Rationale: The 2006 CDC guidelines shifted to routine, opt-out HIV
screening for all patients aged 13-64 in healthcare settings, removing
the requirement for separate written consent and extensive pre-test
counseling.
,5. What is the most common type of menstrual dysfunction associated
with hyperandrogenism, such as in Polycystic Ovary Syndrome
(PCOS)?
A. Primary dysmenorrhea
B. Hypomenorrhea
C. Irregular bleeding (oligomenorrhea/amenorrhea)
D. Menorrhagia
Correct Answer: C
Rationale: Hyperandrogenism disrupts the hypothalamic-pituitary-
ovarian axis, leading to chronic anovulation, which typically manifests as
irregular, infrequent bleeding (oligomenorrhea) or complete absence of
menstruation (amenorrhea).
6. Which statement about the subdermal progestin implant (e.g.,
Nexplanon) is false?
A. It provides contraceptive protection for up to 3 years
B. After removal, its contraceptive effects last 10 more months on
average
C. It is a highly effective, long-acting reversible contraceptive
D. Irregular bleeding is a common side effect
Correct Answer: B
Rationale: The subdermal progestin implant is effective for 3 years.
Once removed, the contraceptive effect wears off rapidly, typically
within days, and does not persist for 10 months.
7. What is the most common symptom of vulvovaginal candidiasis?
A. Foul, fishy-smelling vaginal discharge
B. Dysuria and urinary frequency
C. Thick, white, cottage cheese-like discharge
D. Vulvar pruritus
, Correct Answer: D
Rationale: While cottage cheese-like discharge is classic, vulvar pruritus
(itching) is overwhelmingly the most common and bothersome
symptom reported by patients with vulvovaginal candidiasis.
8. A patient presents with breast pain. Which of the following
characteristics suggests non-cyclic mastalgia?
A. Pain is bilateral and diffuse
B. Pain is localized to the upper outer quadrant of one breast
C. Pain is associated with the luteal phase of the menstrual cycle
D. Pain resolves with the onset of menses
Correct Answer: B
Rationale: Non-cyclic mastalgia is typically unilateral, localized, and
often described as sharp or burning, whereas cyclic mastalgia is usually
bilateral, diffuse, and tied to the menstrual cycle.
9. Which diagnostic tool is considered the gold standard for confirming
a diagnosis of adenomyosis?
A. Transvaginal ultrasound
B. Endometrial biopsy
C. Magnetic Resonance Imaging (MRI)
D. Hysteroscopy
Correct Answer: C
Rationale: While transvaginal ultrasound is often the first-line imaging,
MRI is considered the gold standard non-invasive diagnostic tool for
adenomyosis, showing thickening of the junctional zone. Histology after
hysterectomy is definitive.
10. A 28-year-old woman with PCOS is experiencing irregular bleeding.
Which underlying mechanism best explains this?
