,Question 1
A 55-year-old man with a history of hypertension and type 2 diabetes presents with acute onset of
crushing chest pain and dyspnea. ECG shows ST-segment elevation in leads V1-V4. He is given
aspirin, ticagrelor, and heparin. Which of the following is the most appropriate next step in
management according to current ACC/AHA guidelines?
A) Immediate coronary angiography with PCI within 90 minutes
B) Fibrinolysis if PCI cannot be performed within 120 minutes
C) Deferred angiography at 24-48 hours after medical stabilization
D) Conservative medical management with watchful waiting
Answer: A) Immediate coronary angiography with PCI within 90 minutes
Explanation: For STEMI, current guidelines recommend primary PCI within 90 minutes of first
medical contact. If timely PCI is not available, fibrinolysis is given within 30 minutes.
Options C and D are appropriate only for NSTEMI or stable angina, not STEMI.
Question 2
A patient with decompensated cirrhosis and ascites develops spontaneous bacterial peritonitis
(SBP). Paracentesis reveals a neutrophil count of 350 cells/L. Which of the following is the most
appropriate antibiotic regimen and adjunctive therapy per AASLD guidelines?
A) Ceftriaxone 2 g IV daily plus albumin 1.5 g/kg on day 1 and 1 g/kg on day 3
B) Cefotaxime 2 g IV q8h plus albumin 1.5 g/kg on day 1 and 1 g/kg on day 3
C) Levofloxacin 500 mg IV daily plus albumin 1 g/kg on day 1 only
D) Metronidazole 500 mg IV q8h plus albumin 1 g/kg on day 1 and day 3
Answer: B) Cefotaxime 2 g IV q8h plus albumin 1.5 g/kg on day 1 and 1 g/kg on day 3
Explanation: Cefotaxime is the first-line antibiotic for SBP. Albumin infusion (1.5 g/kg at diagnosis,
1 g/kg on day 3) reduces the risk of renal impairment and mortality. Ceftriaxone is an
alternative but cefotaxime is preferred in trials. Levofloxacin is used for prophylaxis,
not treatment. Metronidazole lacks gram-negative coverage.

,Question 3
Which of the following best describes the mechanism of action of the mRNA-1273 (Moderna)
COVID-19 vaccine?
A) It delivers inactivated SARS-CoV-2 virus to stimulate antibody production.
B) It introduces a viral vector encoding the spike protein to induce cellular immunity.
C) It uses lipid nanoparticles to deliver mRNA encoding the spike protein, which is then translated by
host cells.
D) It contains recombinant spike protein adjuvanted with AS03 to enhance immune response.
Answer: C) It uses lipid nanoparticles to deliver mRNA encoding the spike protein, which is then
translated by host cells.
Explanation: mRNA vaccines like Moderna's use lipid nanoparticles to deliver synthetic mRNA that
codes for the spike protein. Host cells produce the protein, triggering an immune
response. Option A describes inactivated vaccines, B describes viral vector vaccines,
and D describes protein subunit vaccines.
Question 4
A patient with chronic kidney disease stage G4 (eGFR 25 mL/min/1.73m²) has persistent
hyperkalemia (K+ 5.8 mEq/L) despite dietary restriction and optimization of diuretics. Which of
the following medications is most appropriate to add for long-term management?
A) Sodium polystyrene sulfonate
B) Patiromer
C) Calcium gluconate
D) Insulin plus dextrose
Answer: B) Patiromer
Explanation: Patiromer is a potassium-binding resin approved for chronic hyperkalemia in CKD
patients. Sodium polystyrene sulfonate is also used but has been associated with colonic
necrosis and is less preferred. Calcium gluconate and insulin+dextrose are acute
treatments for life-threatening hyperkalemia, not for long-term management.

, Question 5
A 65-year-old man with COPD (GOLD stage 2) and a 40-pack-year smoking history presents with
progressive dyspnea and cough. Spirometry shows FEV1/FVC 0.60, FEV1 55% predicted. He has
had two exacerbations in the past year requiring antibiotics and systemic corticosteroids.
According to the GOLD 2023 report, what is the most appropriate initial pharmacologic
treatment?
A) LAMA alone (e.g., tiotropium)
B) LAMA/LABA combination (e.g., tiotropium/olodaterol)
C) ICS/LABA combination (e.g., fluticasone/salmeterol)
D) Triple therapy with ICS/LAMA/LABA
Answer: B) LAMA/LABA combination (e.g., tiotropium/olodaterol)
Explanation: GOLD 2023 recommends LAMA/LABA as initial therapy for group E patients (high
symptom burden and 2 moderate exacerbations or 1 hospitalization). This patient is
group E. ICS is added if eosinophils 300 cells/L; triple therapy is reserved for those who
continue to exacerbate on LAMA/LABA. LAMA alone is insufficient for group E.
Question 6
A 35-year-old woman presents with acute-onset severe headache, hypertension (180/110 mmHg),
and diaphoresis. Laboratory studies show elevated plasma metanephrines. CT abdomen reveals a 4
cm adrenal mass. Which of the following is the most appropriate preoperative preparation?
A) Start phenoxybenzamine 10 mg BID, titrate to blood pressure control, then add beta-blocker after
adequate alpha blockade
B) Start metoprolol 50 mg BID, then add prazosin if needed
C) Start labetalol 200 mg BID, titrate to effect
D) Start amlodipine 5 mg daily and monitor for arrhythmias
Answer: A) Start phenoxybenzamine 10 mg BID, titrate to blood pressure control, then add
beta-blocker after adequate alpha blockade
Explanation: For pheochromocytoma, preoperative alpha blockade with phenoxybenzamine
(non-selective, long-acting) is standard. Beta-blockade is added after alpha blockade to
prevent unopposed alpha stimulation and hypertensive crisis. Labetalol has both alpha
and beta effects but is not first-line. Beta-blockers alone can cause paradoxical
hypertension.
