Section 1: Women's Health & Preventive Screening (Questions 1–35)
1. A 21-year-old female presents for her first well-woman exam and has never been sexually
active. According to ACOG guidelines, which screening should the APRN recommend at this
visit?
A. Pelvic ultrasonography to evaluate ovarian health
B. Mammogram to establish a baseline for breast tissue
C. Pap smear for cervical cancer screening
D. HPV co-testing to assess for high-risk strains
Rationale: C. The American College of Obstetricians and Gynecologists recommends initiating
Pap smear screening for women at age 21, regardless of sexual activity history, making
cervical cytology the appropriate screening tool at this visit. HPV co-testing begins at age 30,
and mammography is typically initiated at age 40 or 50 based on risk factors.
2. A 67-year-old woman has had three consecutive negative Pap cytology results, with her
most recent test performed 3 years ago. What should the APRN recommend regarding her
next screening?
A. Continue Pap smears every 3 years indefinitely
B. Schedule Pap smear every 5 years with HPV co-testing
C. Discontinue routine cervical cancer screening

D. Perform annual Pap smears for the next 5 years
Rationale: C. Routine cervical cancer screening can be discontinued after age 65 if the patient
has had three consecutive negative cytology results or two consecutive negative co-testing
results within the prior 10 years, with the most recent test within 5 years. No further
screening is recommended for this patient.
3. A 52-year-old female presents with intense vulvar and vaginal itching, thick white "cottage
cheese" discharge, and vulvar erythema. Which diagnosis should the APRN make for this
patient?
A. Bacterial vaginosis characterized by thin gray discharge
B. Vulvovaginal candidiasis with typical fungal symptoms
C. Trichomoniasis presenting with frothy yellow-green discharge
D. Atrophic vaginitis related to postmenopausal changes
Rationale: B. The classic presentation of vulvovaginal candidiasis includes intense pruritus,
thick white "cottage cheese-like" discharge, and vulvar erythema. Vaginal pH is typically
normal (3.8-4.5) in candidiasis, unlike BV or trichomoniasis where the pH is elevated.
4. A 30-year-old female presents with a thin, homogeneous gray discharge with a fishy odor
that is more noticeable after intercourse. What is the most likely diagnosis?
A. Vulvovaginal candidiasis with thick white discharge
B. Bacterial vaginosis with characteristic amine odor
C. Trichomoniasis with frothy green discharge
D. Chlamydia infection with mucopurulent discharge
Rationale: B. Bacterial vaginosis classically causes a thin, homogeneous discharge with a
characteristic fishy amine odor that is often more noticeable after intercourse due to the
alkalinity of semen. This is caused by an overgrowth of anaerobic bacteria and a disruption of
normal vaginal flora.
5. A 28-year-old female presents with vulvar tenderness, burning, and edema. A wet mount
preparation reveals the presence of pseudohyphae and spores. What is the most likely
diagnosis?

,Page 3 of 78
A. Bacterial vaginosis with clue cells on microscopy
B. Vulvovaginal candidiasis with fungal elements present
C. Trichomoniasis with flagellated protozoa observed
D. Herpes simplex virus infection with vesicular lesions
Rationale: B. The presence of pseudohyphae and spores on a wet mount preparation with
potassium hydroxide is diagnostic for candida infection, also known as vulvovaginal
candidiasis. Bacterial vaginosis shows clue cells, trichomoniasis shows flagellated protozoa,
and HSV presents with vesicular lesions.
6. A 35-year-old female presents with vaginal irritation and a wet mount that shows
flagellated protozoa. The cervix appears inflamed and friable on examination. What is the
most likely causative agent?
A. Candida albicans causing fungal vaginal infection
B. Trichomonas vaginalis causing protozoan infection
C. Gardnerella vaginalis associated with bacterial vaginosis
D. Herpes simplex virus causing genital herpes
Rationale: B. The presence of flagellated protozoa on the wet mount is indicative of
trichomoniasis, a sexually transmitted infection caused by Trichomonas vaginalis. The
"strawberry cervix" appearance with inflamed, friable tissue is a classic finding in
trichomoniasis.
7. A 42-year-old woman presents for preventive care and has never undergone breast cancer
screening. Which approach is most appropriate for this patient?
A. Wait until age 60 because she has no family history of breast cancer
B. Order annual breast MRI as the only screening test for this patient
C. Discuss and initiate age-appropriate mammography screening
D. Screening is unnecessary without breast symptoms or concerns
Rationale: C. Average-risk women in this age range should receive age-appropriate
mammographic screening rather than waiting for symptoms or relying on MRI alone.
Mammography remains the gold standard for breast cancer screening in average-risk women
beginning at age 40-50.

8. A 55-year-old woman presents with a new hard, irregular, fixed breast mass on self-
examination. Which finding warrants prompt diagnostic evaluation rather than routine
screening alone?
A. Bilateral cyclic breast tenderness that varies with menstrual cycle
B. Symmetric nodularity felt before the onset of menstruation
C. A new hard, irregular, fixed breast mass on examination
D. Mild breast tenderness reported after engaging in exercise
Rationale: C. A new suspicious breast mass requires diagnostic imaging and further evaluation
because its characteristics (hard, irregular, fixed) may indicate malignancy. Cyclic tenderness
and symmetric nodularity are typically benign findings.
9. A 45-year-old female presents with symptoms of urine leakage during physical exertion
such as coughing, sneezing, or laughing. What diagnostic test is most appropriate for this type
of incontinence?
A. Urodynamic testing with cystometry for bladder pressure measurement
B. Cough stress test to observe for urine leakage with increased abdominal pressure
C. Ultrasound to evaluate for structural abnormalities of the urinary tract
D. Cystoscopy to visualize the bladder lining directly
Rationale: B. The cough stress test is a simple, non-invasive diagnostic test for stress
incontinence. The provider observes for urine leakage when the patient coughs vigorously,
confirming the diagnosis of stress urinary incontinence.
10. A 48-year-old female presents with concerns about ovarian cancer risk. Which of the
following is NOT considered a risk factor for ovarian cancer?
A. Caucasian race with Northern European ancestry
B. Multiparity with multiple pregnancies carried to term
C. Late onset of menopause after age 55
D. Family history of ovarian or breast cancer
Rationale: B. Nulliparity (never having carried a pregnancy to term) is associated with an
increased incidence of ovarian cancer. Conversely, multiparity is protective. Other risk factors
include Caucasian race, late menopause, and family history.
