1. A 67-year-old man with hypertension, type 2 diabetes mellitus,
chronic kidney disease stage 3, and heart failure with reduced
ejection fraction presents with progressive dyspnea, orthopnea,
and bilateral lower-extremity edema. Examination reveals jugular
venous distention, bibasilar crackles, and pitting edema.
Laboratory studies show BNP 1,500 pg/mL and creatinine 1.8
mg/dL. Which intervention is most appropriate initially?
A. Intravenous nitroprusside
B. Oral hydrochlorothiazide
C. Intravenous furosemide
D. Immediate hemodialysis
E. Digoxin loading dose
Answer: C. Intravenous furosemide
Rationale: Acute decompensated heart failure with volume overload
requires rapid diuresis. Loop diuretics such as furosemide reduce
preload and improve symptoms. Dialysis is reserved for refractory
volume overload or severe renal failure.
2. A 29-year-old woman presents with fever, hypotension, diffuse
erythroderma, vomiting, and diarrhea during menstruation. She
has been using superabsorbent tampons. Which organism is most
likely responsible?
,A. Streptococcus pneumoniae
B. Escherichia coli
C. Staphylococcus aureus
D. Neisseria gonorrhoeae
E. Clostridium difficile
Answer: C. Staphylococcus aureus
Rationale: Toxic shock syndrome is caused by toxin-producing
Staphylococcus aureus. Clinical findings include fever, diffuse rash,
hypotension, and multiorgan involvement.
3. A 73-year-old smoker presents with sudden painless monocular
vision loss lasting 20 minutes. Symptoms resolve before arrival.
What is the most likely diagnosis?
A. Acute angle-closure glaucoma
B. Retinal detachment
C. Amaurosis fugax
D. Optic neuritis
E. Migraine aura
Answer: C. Amaurosis fugax
Rationale: Transient monocular blindness due to retinal ischemia is
usually caused by carotid artery atherosclerotic embolization and
should prompt stroke evaluation.
4. A hospitalized patient develops acute respiratory distress 8 hours
after receiving multiple blood transfusions. Chest radiograph
reveals bilateral pulmonary infiltrates without evidence of heart
failure. What is the diagnosis?
,A. TRALI
B. TACO
C. ARDS from sepsis
D. Pulmonary embolism
E. Aspiration pneumonia
Answer: A. TRALI
Rationale: Transfusion-related acute lung injury presents within 6
hours of transfusion with noncardiogenic pulmonary edema and
hypoxemia.
5. A 42-year-old woman reports fatigue, pruritus, and progressive
jaundice. Laboratory studies reveal elevated alkaline phosphatase
and positive antimitochondrial antibodies. Which diagnosis is
most likely?
A. Primary sclerosing cholangitis
B. Autoimmune hepatitis
C. Primary biliary cholangitis
D. Hemochromatosis
E. Wilson disease
Answer: C. Primary biliary cholangitis
Rationale: Primary biliary cholangitis commonly affects middle-aged
women and is associated with antimitochondrial antibodies and
cholestatic liver enzyme elevation.
6. A 64-year-old man with atrial fibrillation develops sudden
abdominal pain that is out of proportion to physical findings.
Lactate is elevated. What is the most likely diagnosis?
, A. Diverticulitis
B. Acute mesenteric ischemia
C. Small bowel obstruction
D. Acute pancreatitis
E. Cholecystitis
Answer: B. Acute mesenteric ischemia
Rationale: Embolic occlusion of mesenteric vessels causes severe
abdominal pain out of proportion to examination findings and
elevated lactate.
7. A patient with septic shock remains hypotensive despite adequate
fluid resuscitation. Which vasopressor should be initiated first?
A. Dopamine
B. Epinephrine
C. Phenylephrine
D. Norepinephrine
E. Vasopressin
Answer: D. Norepinephrine
Rationale: Norepinephrine is the first-line vasopressor for septic shock
due to potent alpha-adrenergic vasoconstrictive effects with relatively
limited arrhythmogenicity.
8. A newborn develops cataracts, patent ductus arteriosus, and
sensorineural hearing loss. Congenital infection with which
pathogen is most likely?
A. Cytomegalovirus
B. Rubella virus
