1. 1A patient with recurrent abdominal discomfort is being evaluated for possible irritable bowel syndrome. The FNP has documented stool frequency and appearance. Which question completes assessment of the characteristic relationship between pain and bowel function?

   1. A. Does the pain change after you have a bowel movement?
   2. B. Does the pain change after you swallow a solid meal?
   3. C. Does the pain change after you empty your bladder?
   4. D. Does the pain change after you take a deep breath?

   Answer: A

   Explanation: NIDDK states, "Your pain is related to your bowel movements. For example, your pain may improve or get worse after bowel movements." Asking about defecation completes this symptom relationship; swallowing, urination, and inspiration assess other relationships and do not establish it.

2. 2A woman has thin homogeneous vaginal discharge, vaginal pH 5.2, a positive amine odor test, and clue cells. Which diagnosis best explains this combination?

   1. A. Vulvovaginal candidiasis
   2. B. Bacterial vaginosis
   3. C. Genital herpes infection
   4. D. Atrophic vaginitis

   Answer: B

   Explanation: CDC lists "Clue cells (e.g., vaginal epithelial cells studded with adherent bacteria) on microscopic examination", "pH of vaginal fluid >4.5", and "A fishy odor of vaginal discharge before or after addition of 10% KOH (i.e., the whiff test)" among the Amsel criteria for BV. These three findings, together with homogeneous thin discharge, meet the requirement for at least three criteria. Yeast, herpes, and atrophic vaginitis do not best explain this complete combination.

3. 3An adult has uncomplicated bacterial rhinosinusitis, prefers to avoid immediate antibiotics, and can reliably return if symptoms worsen. Which initial plan is consistent with CDC guidance and the patient's preference?

   1. A. Arrange watchful waiting with reliable clinical follow-up.
   2. B. Arrange immediate macrolide therapy with routine clinical follow-up.
   3. C. Arrange immediate sinus radiographs with routine clinical follow-up.
   4. D. Arrange immediate respiratory fluoroquinolone therapy with follow-up.

   Answer: A

   Explanation: CDC states, "Healthcare professionals should encourage watchful waiting for uncomplicated cases for which reliable follow-up is available." This patient meets those conditions and prefers observation. Routine radiographs and immediate broad or resistance-prone antibiotic choices do not match the indicated initial strategy.

4. 4A woman starts outpatient treatment for mild-to-moderate PID. The FNP arranges early reassessment of fever and pelvic tenderness. Within what interval should clinical improvement ordinarily be evident according to CDC?

   1. A. Within approximately two weeks of treatment initiation
   2. B. Within approximately one month of treatment initiation
   3. C. Within approximately three days of treatment initiation
   4. D. Within approximately one week of treatment initiation

   Answer: C

   Explanation: CDC states, "Women should demonstrate clinical improvement" and specifies "<3 days after therapy initiation." Early improvement in fever and tenderness should occur by this interval; waiting one to four weeks would miss the recommended early response assessment.

5. 5During evaluation of newly elevated thyroid hormone levels, a patient reports taking a supplement made from seaweed. Which nutrient intake should the FNP quantify to investigate a potential contributor to thyroid hormone excess?

   1. A. Daily calcium intake
   2. B. Daily iodine intake
   3. C. Daily folate intake
   4. D. Daily iron intake

   Answer: B

   Explanation: NIDDK explains, "In some people, consuming large amounts of iodine may cause the thyroid to make too much thyroid hormone." Seaweed products can supply substantial iodine. Quantifying iodine exposure addresses this mechanism; calcium, folate, and iron do not substitute for an iodine history.

6. 6Vulvar itching, edema, and thick curdy discharge prompt a vaginal wet preparation. KOH microscopy shows budding yeast and pseudohyphae; pH is 4.2. What is the most likely diagnosis?

   1. A. Bacterial vaginosis
   2. B. Trichomonal vaginitis
   3. C. Gonococcal cervicitis
   4. D. Vulvovaginal candidiasis

   Answer: D

   Explanation: CDC supports diagnosis when a wet preparation "demonstrates budding yeasts, hyphae, or pseudohyphae". Yeast structures with the symptoms and normal acidic pH support candidiasis. The alternatives do not account for those fungal findings.

7. 7A healthy adult has uncomplicated acute bronchitis with colored sputum. Vital signs and lung examination do not suggest pneumonia. Which management plan should the FNP recommend?

   1. A. Begin a short macrolide course with symptom management.
   2. B. Use symptom management without routine antibiotic therapy.
   3. C. Begin an oral cephalosporin course with symptom management.
   4. D. Begin an amoxicillin-clavulanate course with symptom management.

   Answer: B

   Explanation: CDC states, "Routine treatment of uncomplicated acute bronchitis with antibiotics is not recommended, regardless of cough duration." It also notes that colored sputum does not establish bacterial infection. Symptom care is appropriate; none of the antibiotic strategies gains an indication from sputum color.

   Reference: Outpatient Clinical Care for Adults — Adult treatment recommendations — Acute uncomplicated bronchitis

8. 8After recommended treatment for bacterial vaginosis, a woman's discharge and odor resolve completely. What follow-up plan best matches CDC guidance?

   1. A. Schedule routine clinical review seven days after treatment.
   2. B. Schedule routine clinical review fourteen days after treatment.
   3. C. Schedule routine clinical review three months after treatment.
   4. D. Arrange return evaluation if symptoms persist or recur.

   Answer: D

   Explanation: CDC states, "Follow-up visits are unnecessary if symptoms resolve." Persistent or recurrent symptoms warrant return evaluation. Routine weekly cultures or mandatory testing at two weeks or three months is not the stated BV follow-up plan.

9. 9An adult reports a single sexual partner in the past year. Both partners currently describe the relationship as exclusive. Before considering this an established low-risk partnership, what additional relationship history should the FNP obtain?

   1. A. Whether the partner lives in the same household
   2. B. Whether the partner is approximately the same age
   3. C. Whether the partner is a new sexual partner
   4. D. Whether the partner has the same marital status

   Answer: C

   Explanation: CDC advises, "Even if only one sex partner is noted over the last 12 months, be certain to inquire if that partner is a new sex partner." Current exclusivity does not establish the duration or prior exposure history of the relationship. Residence, similar age, and marital status do not answer whether the partnership is new.

10. 10A sexually active woman has diffuse yellow-green malodorous vaginal discharge and vulvar irritation. Examination reveals a strawberry-appearing cervix. Which infection should be prioritized while obtaining confirmatory testing?

    1. A. Trichomoniasis
    2. B. Vulvovaginal candidiasis
    3. C. Bacterial vaginosis
    4. D. Genital herpes

    Answer: A

    Explanation: CDC describes trichomoniasis discharge as "diffuse, malodorous, or yellow-green" and notes a "strawberry-appearing cervix". This combination most strongly suggests trichomoniasis. Yeast, BV, and herpes have different typical findings; confirmatory testing remains appropriate.
