,Q1. A primary care provider is evaluating a patient with classic signs of acute
sinusitis but also notes subtle orbital swelling and pain with extraocular movements.
Which diagnostic approach is most appropriate before initiating antibiotics?
A. Prescribe amoxicillin-clavulanate and reassess in 48-72 hours
B. Order a contrast-enhanced CT of the sinuses and orbits to rule out orbital
complications
C. Initiate intranasal corticosteroids and saline irrigation for 7 days
D. Refer for endoscopic sinus surgery for tissue biopsy
Correct Answer: B. Order a contrast-enhanced CT of the sinuses and orbits to rule
out orbital complications
Rationale: Orbital swelling and pain with extraocular movements suggest orbital
cellulitis, a complication of sinusitis requiring urgent imaging (CT with contrast) and
likely IV antibiotics. Antibiotics alone without imaging delay definitive management.
Intranasal steroids and saline are adjunctive, not first-line for suspected complications.
Surgery is not indicated without confirmed abscess or failed medical therapy.
Why Wrong:
A - While antibiotics are needed, imaging is essential to confirm orbital involvement
and guide surgical intervention if an abscess is present.
C - These are symptomatic adjuncts and do not address the potential orbital
complication.
D - Surgical referral is premature without imaging confirmation of an abscess or other
surgical indication.

sinusitis. Otolaryngology-Head and Neck Surgery, 152(2_suppl), S1-S39.
Q2. In a patient with suspected acute coronary syndrome presenting with atypical
symptoms, which electrocardiographic finding is most specific for acute myocardial
ischemia?
A. T-wave inversion in leads V1-V3
B. ST-segment depression with dynamic T-wave changes
C. New left bundle branch block
D. Hyperacute T-waves with prominent upright T-waves in two contiguous leads
Correct Answer: D. Hyperacute T-waves with prominent upright T-waves in two
contiguous leads
Rationale: Hyperacute T-waves (broad, tall, symmetric) in contiguous leads are an early,
highly specific sign of acute transmural ischemia. T-wave inversion in V1-V3 can be
normal or due to other causes. ST depression with dynamic T-wave changes is suggestive
but less specific. New LBBB is a criterion for STEMI equivalent but is not as specific as
hyperacute T-waves for ischemia.
Page 3
, Why Wrong:
A - T-wave inversion in V1-V3 can be a normal variant (e.g., persistent juvenile
pattern) or due to non-ischemic causes.
B - ST depression is a common ischemic sign but can also occur with digoxin,
hypokalemia, or LVH with strain.
C - New LBBB is a STEMI equivalent but is not specific to ischemia; it can be
rate-related or due to other conduction disease.

infarction. Circulation, 138(20), e618-e651.
Q3. Which clinical decision rule is most appropriate to estimate pretest probability of
pulmonary embolism in an outpatient with pleuritic chest pain and hypoxia, and how
does it influence the choice of diagnostic testing?
A. Wells score; if low probability, order D-dimer; if high probability, proceed to CT
pulmonary angiography
B. PERC rule; if negative, no further testing; if positive, proceed to CT pulmonary
angiography
C. Geneva score; if low probability, order V/Q scan; if high probability, proceed to CT
pulmonary angiography
D. PESI score; if low risk, treat as outpatient; if high risk, admit
Correct Answer: A. Wells score; if low probability, order D-dimer; if high
probability, proceed to CT pulmonary angiography
Rationale: The Wells score is a validated clinical prediction rule for PE. In a patient with
pleuritic chest pain and hypoxia, it helps determine pretest probability. If Wells is low, a
D-dimer can rule out PE. If high, CT pulmonary angiography is indicated. The PERC rule
is used to rule out PE without testing only in very low-risk patients; it does not guide
further testing. The Geneva score is also valid but less commonly used in the US. PESI
assesses mortality risk, not pretest probability.
Why Wrong:
B - PERC rule is for ruling out PE in low-risk patients, not for guiding testing in
symptomatic patients with hypoxia.
C - Geneva score is valid but not the standard first-line in US practice; V/Q scan is not
the preferred initial imaging in most settings.
D - PESI is for prognosis and treatment setting, not for diagnostic testing decisions.

management of acute pulmonary embolism. European Heart Journal, 41(4),
