What is the first thing you should do for a patient with suspected cardiogenic shock?

• A. Start Intravenous Fluids
• B. Obtain a 12-lead ECG and capnography
• C. Administer Epinephrine
• D. Assess for Neurogenic Signs

Answer: (C)

In cardiogenic shock, the priority is to restore perfusion by supporting the heart’s pumping ability. Epinephrine acts as both an inotrope and a vasopressor, increasing heart contractility and vascular tone. This raises cardiac output and mean arterial pressure, which improves perfusion to vital organs quickly—exactly what you need when the pump isn’t delivering enough blood. It buys time for definitive management (like addressing the underlying cause of the shock) to take effect. Starting IV fluids is risky here because the heart isn’t handling the volume well; adding fluids can worsen pulmonary edema and left-sided pressures. While a 12-lead ECG and capnography are important for diagnosing and monitoring the patient, they don’t immediately correct the dangerous perfusion deficit. Neurogenic signs aren’t the primary driver in cardiogenic shock, so they don’t guide the immediate first action.
