ABSTRACT
This study document brings together 49 carefully worded exam questions drawn from NR547
Differential Diagnosis CEA Diagnostic Exam Questions and Correct Answers Latest 2026-2027
Update Graded A+, with the strongest emphasis placed on Synthesize subjective and objective
data to formulate prioritized differential diagnoses, Select and interpret diagnostic studies using
current evidence-based guidelines and Apply pathophysiologic principles to distinguish between
similar clinical presentations. Every item follows the wording style and level of reasoning you meet
in the real paper, and each one is paired with a clear rationale so the correct choice is never a
guess. Work through the set at your own pace, mark the questions that slow you down, then come
back to them until the reasoning feels automatic. Learners who revise this way walk into the exam
room recognising the pattern behind the questions instead of meeting them for the first time. Keep
going - steady, honest practice is what turns a difficult paper into a comfortable pass.

,Q1 SYNTHESIZE SUBJECTIVE AND OBJECTIVE DATA TO FORMULATE PRIORITIZED
DIFFERENTIAL DIAGNOSES
A patient presents with unilateral, throbbing headache, ipsilateral ptosis, miosis,
and nasal congestion. Which pathophysiologic mechanism best explains this
presentation?
A. Activation of the trigeminovascular system with cortical spreading depression
B. Hypothalamic dysregulation causing parasympathetic activation and sympathetic
hypofunction CORRECT
C. Sterile inflammation of the cavernous sinus with cranial nerve compression
D. Impaired venous drainage leading to increased intracranial pressure
RATIONALE: This cluster headache presentation is driven by hypothalamic activation and
autonomic dysfunction, with parasympathetic overactivity (lacrimation, congestion) and
sympathetic hypofunction (ptosis, miosis). Migraine (A) lacks these autonomic features.
Cavernous sinus thrombosis (C) would present with more diffuse symptoms and systemic illness.
Q2 SYNTHESIZE SUBJECTIVE AND OBJECTIVE DATA TO FORMULATE PRIORITIZED
DIFFERENTIAL DIAGNOSES
Which finding on thyroid ultrasound is most concerning for malignancy and
warrants fine-needle aspiration?
A. Hyperechoic nodule with smooth margins
B. Hypoechoic nodule with irregular margins and microcalcifications CORRECT
C. Isoechoic nodule with peripheral vascularity
D. Cystic nodule with comet-tail artifacts
RATIONALE: Hypoechoic nodules with irregular margins and microcalcifications are highly
suspicious for papillary thyroid carcinoma. Hyperechoic smooth nodules (A) and cystic with
comet-tail (D) are typically benign. Isoechoic with peripheral vascularity (C) is nonspecific.

, Q3 SYNTHESIZE SUBJECTIVE AND OBJECTIVE DATA TO FORMULATE PRIORITIZED
DIFFERENTIAL DIAGNOSES
A patient with known heart failure presents with worsening dyspnea and
orthopnea. Which diagnostic test is most useful for differentiating decompensated
heart failure from COPD exacerbation?
A. Chest X-ray
B. BNP level CORRECT
C. Pulmonary function tests
D. Arterial blood gas
RATIONALE: BNP is highly sensitive for heart failure and helps differentiate from COPD
exacerbation, where BNP is typically normal. Chest X-ray (A) can show cardiomegaly or edema
but is less specific. PFTs (C) are not useful acutely, and ABG (D) shows hypoxia/hypercapnia in
both.
Q4 SYNTHESIZE SUBJECTIVE AND OBJECTIVE DATA TO FORMULATE PRIORITIZED
DIFFERENTIAL DIAGNOSES
A patient presents with acute monoarticular arthritis of the knee. Which synovial
fluid finding is most consistent with gout?
A. Needle-shaped negatively birefringent crystals CORRECT
B. Rhomboid-shaped positively birefringent crystals
C. Gram-positive cocci in clusters
D. Monosodium urate crystals with low white blood cell count
RATIONALE: Gout is caused by monosodium urate crystals, which are needle-shaped and
negatively birefringent. Pseudogout (B) has rhomboid, positively birefringent calcium
pyrophosphate crystals. Septic arthritis (C) shows bacteria. Gout typically has high WBC count,
not low (D).
