most likely diagnosis?
A. COPD
B. Pulmonary embolism
C. Heart failure
D. Pneumonia
Correct Answer: C. Heart failure
S3 gallop, volume overload symptoms, and peripheral edema are
classic for systolic heart failure due to increased ventricular filling
pressures.
,2. A patient has sudden chest pain radiating to the back with unequal
blood pressures in both arms. What is the most likely diagnosis?
A. Myocardial infarction
B. Aortic dissection
C. Pericarditis
D. Pneumothorax
Correct Answer: B. Aortic dissection
Tearing chest pain with pulse/BP differential strongly suggests aortic
dissection involving branch vessel obstruction.
3. A child presents with a “slapped cheek” rash and mild fever. What is
the causative agent?
A. Epstein-Barr virus
B. Parvovirus B19
C. Rubella virus
D. Measles virus

5. A patient has tremor at rest, rigidity, and bradykinesia. What is the
underlying pathology?
A. Loss of dopamine in substantia nigra
B. Excess acetylcholine in cortex
C. Demyelination of corticospinal tract
D. Cerebellar degeneration
Correct Answer: A. Loss of dopamine in substantia nigra
Parkinson disease is caused by degeneration of dopaminergic
neurons in the substantia nigra pars compacta.
6. Which condition is associated with anti-double stranded DNA
antibodies?
A. Rheumatoid arthritis
B. Systemic lupus erythematosus
C. Scleroderma
D. Sjögren syndrome
Correct Answer: B. Systemic lupus erythematosus
, Anti-dsDNA antibodies are highly specific for SLE and correlate with
disease activity.
7. A patient develops wheezing, hypotension, and urticaria after eating
peanuts. What is the best immediate treatment?
A. Oral antihistamine
B. IV steroids
C. Epinephrine
D. Albuterol
Correct Answer: C. Epinephrine
Anaphylaxis requires immediate epinephrine to reverse airway
edema and vasodilation.
8. Which organism causes “walking pneumonia” in young adults?
A. Streptococcus pneumoniae
B. Mycoplasma pneumoniae
C. Klebsiella pneumoniae
D. Haemophilus influenzae
Correct Answer: B. Mycoplasma pneumoniae
