Step 2 CK is a clinical reasoning marathon. Management decisions, ethics, and applied knowledge under time pressure. We built tools for that.

INTERNAL MEDICINE · BLOCK 2
Question 14 of 40
Next best step1:24
A 58-year-old man has had crushing chest pain for 40 minutes. ECG shows ST elevation in leads II, III, and aVF. The nearest PCI-capable hospital is 30 minutes away.
Hint: Find the diagnosis first, then ask how fast reperfusion can happen.(B) Inferior STEMI with PCI reachable within 120 minutes: aspirin, then primary PCI.(A) Lytics are for when PCI can't happen within 120 minutes.
What is the most appropriate next step in management?
AAlteplase in the emergency department
BAspirin and transfer for primary PCI
CCT angiography of the chest
DRepeat troponin in 3 hours
