Introduction:
This comprehensive assessment is designed to evaluate advanced clinical competence, critical thinking, and
diagnostic reasoning for family nurse practitioner students. It assesses the essential skills and knowledge required
to synthesize subjective and objective data, formulate evidence-based differential diagnoses, and implement safe,
comprehensive management plans. Structuring both standard multiple-choice and complex, scenario-based
questions, the exam emphasizes real-world clinical application and safe prescribing practices. Practitioners must
demonstrate professional decision-making aligned with current clinical practice guidelines, ethical standards, and
state and federal regulatory frameworks, ensuring high-quality, patient-centered healthcare delivery across
diverse populations.
Question 1
A 54-year-old male presents with a 3-month history of a persistent, non-productive cough. He has a 30 pack-year
smoking history and denies fever, chills, or weight loss. His chest X-ray reveals a 2 cm solitary pulmonary nodule
,in the right upper lobe with irregular borders. Which of the following is the most appropriate next step in
management?
A. Repeat the chest X-ray in 6 months to monitor for changes in size.
B. Initiate a 10-day course of high-dose amoxicillin-clavulanate.
C. Obtain a computed tomography (CT) scan of the chest with contrast.
D. Schedule an immediate surgical resection of the right upper lobe.
🟢 Correct answer: C. Obtain a computed tomography (CT) scan of the chest with contrast.
🔴 RATIONALE: A solitary pulmonary nodule with irregular borders in a patient with a significant smoking history
carries a high risk of malignancy. A chest CT with contrast is the gold standard next diagnostic step to further
characterize the nodule's characteristics, attenuation, and exact size, guiding subsequent biopsy or management.
Delaying care with a repeat X-ray or giving unnecessary antibiotics is inappropriate, while surgery requires a
definitive tissue diagnosis or detailed staging first.
Question 2
A 29-year-old female at 28 weeks gestation presents with complaints of urinary frequency, urgency, and dysuria
for the past 48 hours. She denies flank pain, fever, or chills. Her urine culture is positive for Escherichia coli
(>100,000 CFU/mL). Which of the following antimicrobial regimens is safest and most effective for this patient?
A. Ciprofloxacin 500 mg orally twice daily for 3 days.
B. Nitrofurantoin monohydrate/macrocrystals 100 mg orally twice daily for 7 days.
C. Trimethoprim-sulfamethoxazole DS 160/800 mg orally twice daily for 3 days.
D. Doxycycline 100 mg orally twice daily for 7 days.
🟢 Correct answer: B. Nitrofurantoin monohydrate/macrocrystals 100 mg orally twice daily for 7 days.
🔴 RATIONALE: Nitrofurantoin is considered safe and highly effective for treating uncomplicated lower urinary
tract infections in pregnant individuals during the second and early third trimesters. Fluoroquinolones
,(ciprofloxacin) are avoided due to potential fetal cartilage toxicities, tetracyclines (doxycycline) cause dental
discoloration and bone growth inhibition, and trimethoprim-sulfamethoxazole should be avoided in late pregnancy
due to risks of kernicterus.
Question 3
A 68-year-old African American female with a history of stage 3 chronic kidney disease (CKD) and type 2 diabetes
presents for a routine follow-up. Her blood pressure over the past three visits has averaged 146/92 mmHg. Her
current medications include metformin and atorvastatin. Which medication should be initiated first to manage her
hypertension?
A. Amlodipine
B. Hydrochlorothiazide
C. Lisinopril
D. Metoprolol succinate
🟢 Correct answer: C. Lisinopril
🔴 RATIONALE: In patients with chronic kidney disease and diabetes mellitus, angiotensin-converting enzyme
(ACE) inhibitors, such as lisinopril, or angiotensin receptor blockers (ARBs) are preferred first-line agents. They
provide renoprotective effects by dilating the efferent arteriole, reducing intraglomerular pressure, and slowing the
progression of diabetic nephropathy, regardless of the patient's race.
Question 4
A 45-year-old male complains of severe, sudden-onset pain, swelling, and erythema in his left first
metatarsophalangeal (MTP) joint that began last night after attending a steak dinner. He is diagnosed with an
acute gouty flare. He has no history of renal disease or peptic ulcers. Which is the preferred first-line agent for
acute symptom relief?
, A. Indomethacin
B. Allopurinol
C. Febuxostat
D. Probenecid
🟢 Correct answer: A. Indomethacin
🔴 RATIONALE: Nonsteroidal anti-inflammatory drugs (NSAIDs) like indomethacin, naproxen, or high-dose
aspirin, along with colchicine and systemic corticosteroids, are first-line choices for an acute gout flare. Urate-
lowering therapies like allopurinol, febuxostat, and probenecid should never be initiated or adjusted during an
acute flare, as abrupt shifts in serum uric acid levels can worsen or prolong the acute attack.
Question 5
According to the American Heart Association (AHA) and American College of Cardiology (ACC) guidelines, a
patient with a documented history of atherosclerotic cardiovascular disease (ASCVD), such as a past myocardial
infarction, should be placed on which lipid-lowering regimen?
A. Low-intensity statin therapy
B. Moderate-intensity statin therapy
C. High-intensity statin therapy
D. Statin therapy combined immediately with a PCSK9 inhibitor
🟢 Correct answer: C. High-intensity statin therapy
🔴 RATIONALE: The AHA/ACC cholesterol guidelines recommend high-intensity statin therapy (e.g., atorvastatin
40–80 mg or rosuvastatin 20–40 mg) for secondary prevention in all patients with clinical ASCVD, unless
contraindicated, to lower LDL-C levels by 50% or more. Non-statin therapies are typically added later if LDL
targets are not met with maximally tolerated statin doses.
