1. A 67-year-old man is admitted to the ICU after repair of a
perforated sigmoid diverticulum. On postoperative day 2, he
develops progressive dyspnea, fever, hypotension, and oliguria.
Temperature is 39.2°C, blood pressure is 82/50 mmHg, pulse is
124/min, respiratory rate is 32/min, and oxygen saturation is 88%
on 10 L/min oxygen. Chest radiograph shows bilateral diffuse
alveolar infiltrates without cardiomegaly. Pulmonary capillary
wedge pressure is normal. Which of the following is the most
likely diagnosis?
A. Cardiogenic pulmonary edema
B. Acute respiratory distress syndrome
C. Pulmonary embolism
D. Transfusion-associated circulatory overload
E. Aspiration pneumonia
Answer: B. Acute respiratory distress syndrome
Rationale: ARDS is characterized by acute onset respiratory failure,
bilateral infiltrates, severe hypoxemia, and absence of cardiogenic
pulmonary edema. Sepsis is the most common precipitating factor.
Normal wedge pressure differentiates ARDS from cardiogenic edema.
, 2. A 45-year-old woman presents with fatigue, weight gain,
constipation, and cold intolerance. Laboratory studies show
elevated TSH and low free T4. Which additional finding is most
likely?
A. Hyperreflexia
B. Hypercalcemia
C. Bradycardia
D. Exophthalmos
E. Tremor
Answer: C. Bradycardia
Rationale: Primary hypothyroidism decreases metabolic activity causing
bradycardia, weight gain, constipation, delayed reflex relaxation, and
cold intolerance.
3. A 72-year-old man with atrial fibrillation develops sudden severe
abdominal pain that is disproportionate to physical findings.
Serum lactate is elevated. Which vessel is most likely occluded?
A. Inferior mesenteric artery
B. Superior mesenteric artery
C. Celiac artery
D. Renal artery
E. Internal iliac artery
Answer: B. Superior mesenteric artery
Rationale: Acute mesenteric ischemia classically presents with pain out
of proportion to examination findings. Emboli from atrial fibrillation
most commonly lodge in the superior mesenteric artery.
, 4. A 28-year-old pregnant woman at 34 weeks develops
hypertension, proteinuria, headache, and visual disturbances.
Magnesium sulfate is initiated. The primary purpose of
magnesium sulfate is:
A. Lower blood pressure
B. Improve placental blood flow
C. Prevent seizures
D. Reduce proteinuria
E. Enhance fetal lung maturity
Answer: C. Prevent seizures
Rationale: Magnesium sulfate is administered in preeclampsia with
severe features for seizure prophylaxis. It does not primarily lower blood
pressure.
5. A patient receiving heparin for DVT develops thrombocytopenia
and a new arterial thrombosis on day 7 of therapy. What is the
next best step?
A. Continue heparin and monitor
B. Stop heparin and start argatroban
C. Add aspirin
D. Administer vitamin K
E. Start warfarin immediately
Answer: B. Stop heparin and start argatroban
Rationale: Heparin-induced thrombocytopenia is an immune-mediated
prothrombotic disorder requiring immediate discontinuation of heparin
and initiation of a non-heparin anticoagulant such as argatroban.
, 6. A 59-year-old smoker develops hematuria without pain. Which
diagnosis should be considered first?
A. Renal stone
B. Urinary tract infection
C. Bladder cancer
D. Polycystic kidney disease
E. Glomerulonephritis
Answer: C. Bladder cancer
Rationale: Painless gross hematuria in an older smoker is bladder
cancer until proven otherwise.
7. A 24-year-old woman presents with fatigue and pallor. Laboratory
values show Hb 8 g/dL, MCV 68 fL, ferritin 8 ng/mL. Which is the
most likely diagnosis?
A. Thalassemia major
B. Iron deficiency anemia
C. Sideroblastic anemia
D. Anemia of chronic disease
E. Aplastic anemia
Answer: B. Iron deficiency anemia
Rationale: Low MCV and low ferritin are highly characteristic of iron
deficiency anemia.
8. A patient with septic shock remains hypotensive after adequate
fluid resuscitation. Which vasopressor is first-line?
