1. A 67-year-old man with hypertension and smoking history presents
with sudden severe tearing chest pain radiating to his back. Blood
pressure is 190/100 mmHg in the right arm and 150/85 mmHg in the
left arm. Chest X-ray shows widened mediastinum. What is the most
appropriate next diagnostic step?
A. Exercise stress test
B. CT angiography of the chest
C. Coronary angiography
D. Echocardiography only
Answer: B. CT angiography of the chest
Rationale: Acute aortic dissection is suspected due to tearing pain,
pulse/BP discrepancy, and widened mediastinum. CT angiography is
the preferred diagnostic study in a stable patient because it rapidly
visualizes the aorta and confirms the diagnosis.
2. A 58-year-old woman with diabetes presents with fever, flank pain,
nausea, and costovertebral angle tenderness. Urinalysis shows
leukocyte esterase and nitrites. Which organism is most likely
responsible?
A. Staphylococcus saprophyticus
B. Escherichia coli
,C. Enterococcus faecalis
D. Candida albicans
Answer: B. Escherichia coli
Rationale: E. coli is the most common cause of urinary tract infections,
including pyelonephritis. Diabetes increases risk for complicated
urinary infections.
3. A 45-year-old patient develops progressive difficulty swallowing
first solids and later liquids. Which diagnosis is most likely?
A. Achalasia
B. Esophageal carcinoma
C. GERD
D. Esophageal spasm
Answer: B. Esophageal carcinoma
Rationale: Mechanical obstruction causes progressive dysphagia
beginning with solids and later affecting liquids. Achalasia typically
causes difficulty with both solids and liquids from the beginning.
4. A 72-year-old patient taking warfarin presents with intracranial
bleeding and elevated INR. Which medication should be administered
for rapid reversal?
A. Protamine sulfate
B. Vitamin K only
C. Fresh frozen plasma or prothrombin complex concentrate
D. Aspirin
Answer: C. Fresh frozen plasma or prothrombin complex concentrate
,Rationale: Life-threatening bleeding from warfarin requires rapid
replacement of clotting factors with PCC or FFP plus vitamin K.
5. A 24-year-old woman presents with fatigue, weight gain, cold
intolerance, and constipation. Laboratory studies show elevated TSH
and low free T4. Diagnosis?
A. Hyperthyroidism
B. Primary hypothyroidism
C. Secondary adrenal insufficiency
D. Hyperparathyroidism
Answer: B. Primary hypothyroidism
Rationale: Elevated TSH with decreased thyroid hormone indicates
failure of the thyroid gland itself, causing primary hypothyroidism.
6. A patient with COPD exacerbation has increased dyspnea, increased
sputum volume, and increased sputum purulence. The most
appropriate treatment addition is:
A. Antibiotics
B. Anticoagulation
C. Insulin therapy
D. Diuretics
Answer: A. Antibiotics
Rationale: COPD exacerbations with all three cardinal symptoms
suggest bacterial infection and benefit from antibiotic therapy.
, 7. A 60-year-old man presents with painless hematuria. He has a 40-
pack-year smoking history. What is the most likely diagnosis?
A. Nephrolithiasis
B. Bladder urothelial carcinoma
C. Pyelonephritis
D. Benign prostatic hyperplasia
Answer: B. Bladder urothelial carcinoma
Rationale: Painless gross hematuria in an older smoker is classic for
bladder cancer until proven otherwise.
8. A pregnant patient presents with hypertension, proteinuria, and
edema at 34 weeks gestation. Which medication is used to prevent
seizures?
A. Diazepam
B. Magnesium sulfate
C. Phenytoin
D. Levetiracetam
Answer: B. Magnesium sulfate
Rationale: Magnesium sulfate is first-line seizure prophylaxis for
preeclampsia with severe features and prevention of eclampsia.
9. A 3-year-old child presents with barking cough, inspiratory stridor,
and hoarse voice. The most likely diagnosis is:
A. Epiglottitis
B. Croup
