Q1.
A patient presents with pleuritic chest pain and unilateral leg swelling. Which diagnostic
strategy best balances pretest probability and test characteristics to rule in pulmonary
embolism while minimizing unnecessary testing?
A. Order D-dimer first; if negative, PE is B. Apply the Wells score; if PE is 'likely,'
excluded without further testing. proceed directly to CT pulmonary
angiography (CTPA).
C. Obtain a ventilation-perfusion (V/Q) scan D. Start empiric anticoagulation and defer all
as the initial test of choice in all patients. diagnostic testing until symptoms resolve.
Correct: B - Apply the Wells score; if PE is 'likely,' proceed directly to CT pulmonary
angiography (CTPA).
Rationale:In patients with high pretest probability (Wells score indicating 'likely' PE),
guidelines recommend proceeding directly to CTPA rather than D-dimer, because a negative
D-dimer cannot safely exclude PE in this group. D-dimer is most useful in low-probability
patients, V/Q scan is reserved for specific contraindications to CTPA, and empiric
anticoagulation without diagnosis is unsafe.
Q2.
A patient with a history of recurrent kidney stones presents with new-onset hypertension
and hypokalemia. Which diagnostic test is most specific for identifying the underlying
cause?
A. Serum calcium and parathyroid hormone B. Plasma aldosterone concentration and
levels plasma renin activity
C. 24-hour urine free cortisol D. Renal artery duplex ultrasound
Correct: B - Plasma aldosterone concentration and plasma renin activity
Rationale:The triad of recurrent kidney stones, hypertension, and hypokalemia suggests
primary hyperaldosteronism (Conn syndrome). An elevated aldosterone-to-renin ratio is the
most specific screening test. Calcium/PTH would evaluate hyperparathyroidism, cortisol
evaluates Cushing's, and renal artery duplex evaluates renovascular hypertension, but these
do not fit the full triad as well.

Q3.
Which statement best reflects the principle of 'diagnostic stewardship' in the context of
ordering laboratory tests?
A. Ordering the most comprehensive panel B. Tests should be ordered only when
available ensures no diagnosis is missed. results will meaningfully alter management
and when pretest probability justifies them.
C. Repeating tests at fixed intervals D. Diagnostic stewardship primarily focuses
improves diagnostic accuracy regardless of on reducing costs, not improving patient
clinical change. outcomes.
Correct: B - Tests should be ordered only when results will meaningfully alter
management and when pretest probability justifies them.
Rationale:Diagnostic stewardship emphasizes ordering the right test at the right time for the
right patient, guided by pretest probability and the likelihood that results will change
management. Comprehensive panels can lead to false positives and unnecessary
interventions. Fixed-interval testing ignores clinical context, and stewardship aims to improve
outcomes, not just cut costs.
Q4.
A patient with suspected meningitis undergoes a lumbar puncture. Which cerebrospinal
fluid (CSF) finding most strongly suggests bacterial rather than viral meningitis?
A. Lymphocytic pleocytosis with normal B. Neutrophilic pleocytosis with elevated
glucose protein and low glucose
C. Normal white blood cell count with D. Eosinophilic pleocytosis with normal
elevated opening pressure protein
Correct: B - Neutrophilic pleocytosis with elevated protein and low glucose
Rationale:Bacterial meningitis typically produces a neutrophilic predominance, elevated
protein, and low glucose (CSF/serum ratio <0.4). Viral meningitis usually shows lymphocytic
pleocytosis with normal glucose. Normal WBC count does not suggest meningitis, and
eosinophilic pleocytosis is more typical of parasitic or fungal infections.
Q5.
A patient with a 20-pack-year smoking history presents with a solitary pulmonary nodule
on chest X-ray. Which next step is most appropriate to characterize the nodule?
A. Repeat chest X-ray in 6 months B. Order a low-dose CT scan of the chest
C. Perform a PET-CT immediately D. Refer for surgical resection without
further imaging
