Abstract:
This exam preparation document is a scholarly resource tailored for graduate nursing students in the NR 547 CEA
Differential Diagnosis Practicum. It provides a comprehensive review of advanced health assessment, clinical
reasoning, and differential diagnosis across the lifespan. The content is organized to mirror the course objectives
and the American Association of Nurse Practitioners (AANP) and American Nurses Credentialing Center (ANCC)
certification blueprints. Each of the 250 questions is crafted to test higher-order cognitive skills, including
analysis, synthesis, and evaluation, with detailed rationales that explain both correct and incorrect options. The
document emphasizes the integration of subjective and objective data, diagnostic testing, and evidence-based
practice to formulate accurate differential diagnoses. It also addresses common pitfalls in clinical reasoning and
offers strategies to improve diagnostic accuracy. By engaging with this material, students will enhance their
clinical judgment and readiness for board certification and advanced practice roles.

Chamberlain University, NR 547, Exam prep
Answer Format:
Each question is presented in a multiple-choice format with four options. The correct answer is identified, followed
by a comprehensive rationale explaining why it is correct and why the other options are incorrect. Rationales
include relevant pathophysiology, clinical guidelines, and evidence-based practice recommendations to reinforce
learning.

,Q1. A 45-year-old with a history of hypertension and type 2 diabetes presents with
acute, severe left flank pain radiating to the groin, nausea, and hematuria. Which
diagnostic finding is most definitive for nephrolithiasis?
A. Non-contrast helical CT showing a 5 mm stone at the ureterovesical junction
B. Ultrasound demonstrating hydronephrosis and an echogenic focus in the kidney
C. Urinalysis showing >5 red blood cells per high-power field and pH 7.5
D. Plain abdominal radiograph revealing a radiopaque density over the left renal
shadow
Correct Answer: A. Non-contrast helical CT showing a 5 mm stone at the
ureterovesical junction
Rationale: Non-contrast helical CT is the gold standard for diagnosing nephrolithiasis,
with sensitivity and specificity exceeding 95% for detecting stones of all compositions.
Ultrasound is less sensitive for small stones, particularly in the mid-ureter. Urinalysis and
plain radiographs are supportive but not definitive.
Why Wrong:
B - Ultrasound may miss small stones or those in the mid-ureter, and hydronephrosis
is indirect evidence.
C - Hematuria and pH are nonspecific and can occur in other renal conditions.
D - Plain radiograph fails to visualize uric acid stones and is less sensitive overall.

Evidence-Based Guide, 4th Ed., Ch. 16.
Q2. Which pathophysiological mechanism best explains the development of acute
chest pain in aortic dissection, and how does it differ from that of acute coronary
syndrome (ACS)?
A. Intimal tear leads to intramural hematoma causing ischemia; ACS is due to plaque
rupture causing thrombosis.
B. Aortic dissection causes coronary artery spasm; ACS is due to fixed atherosclerotic
obstruction.
C. Both conditions result from inflammation of the vessel wall, but dissection affects
the aorta while ACS affects coronary arteries.
D. Aortic dissection is caused by embolism from the heart; ACS is due to in-situ
thrombosis.
Correct Answer: A. Intimal tear leads to intramural hematoma causing ischemia;
ACS is due to plaque rupture causing thrombosis.
Rationale: Aortic dissection begins with an intimal tear that allows blood to enter the
media, creating a false lumen and potentially compromising branch vessels, leading to
ischemic pain. ACS typically involves rupture of an atherosclerotic plaque with
superimposed thrombosis, reducing coronary blood flow. The other options misrepresent
Page 3
, the primary mechanisms.
Why Wrong:
B - Coronary artery spasm is not the primary mechanism in dissection; dissection can
extend into coronaries but not cause spasm.
C - Inflammation is not the primary initiating event in either condition.
D - Embolism is not the cause of dissection; in-situ thrombosis is a consequence of
plaque rupture in ACS.

Medicine, 9th Ed., Ch. 51.
Q3. A patient presents with progressive dyspnea, dry cough, and fine bibasilar
crackles on auscultation. Chest imaging shows reticular opacities and honeycombing
in a peripheral, basilar distribution. Which diagnostic test is most likely to confirm
the suspected diagnosis?
A. High-resolution CT (HRCT) of the chest
B. Pulmonary function tests showing restrictive pattern
C. Bronchoalveolar lavage with lymphocytosis
D. Erythrocyte sedimentation rate (ESR) elevation
Correct Answer: A. High-resolution CT (HRCT) of the chest
Rationale: The clinical and imaging features are classic for idiopathic pulmonary fibrosis
(IPF). HRCT demonstrating usual interstitial pneumonia (UIP) pattern, including
honeycombing, is diagnostic in the appropriate clinical context, often obviating the need
for biopsy. PFTs and BAL are supportive but not diagnostic; ESR is nonspecific.
Why Wrong:
B - Restrictive PFTs are seen in many interstitial lung diseases and are not specific.
C - BAL lymphocytosis suggests hypersensitivity pneumonitis, not IPF.
D - ESR is nonspecific and not diagnostic for IPF.

Progressive Pulmonary Fibrosis in Adults: An Official ATS/ERS/JRS/ALAT
Clinical Practice Guideline. Am J Respir Crit Care Med, 205(9), e18-e47.
Q4. In a patient with suspected bacterial meningitis, which cerebrospinal fluid (CSF)
profile is most consistent with the diagnosis, and how does it guide empiric therapy?
A. Increased opening pressure, neutrophilic pleocytosis, elevated protein, low glucose;
empiric vancomycin plus cefotaxime
B. Normal opening pressure, lymphocytic pleocytosis, normal glucose; empiric
acyclovir
C. Decreased opening pressure, eosinophilic pleocytosis, elevated protein; empiric
albendazole
