In a hypotensive patient with signs of cardiogenic shock (SBP <100 mmHg), which medication should be given?

• A. Dopamine infusion
• B. Nitroprusside infusion
• C. Normal saline bolus
• D. Push dose epinephrine 10 mcg IV/IO; may repeat q2-5 min to maintain SBP >90

Answer: (D)

In cardiogenic shock with a systolic BP under 100, the priority is to rapidly improve perfusion by raising blood pressure and boosting heart performance, while avoiding treatments that can worsen edema or drop the pressure further. Nitroprusside acts as a potent afterload reducer and will lower BP, which is dangerous when the patient is already hypotensive. A normal saline bolus isn’t ideal here because adding volume can worsen pulmonary edema and fluid overload in a failing heart. While a dopamine infusion can raise BP, a push-dose epinephrine approach provides quick, titratable inotropic and vasoconstrictive support. Small, rapid doses of epinephrine (10 mcg IV/IO) can quickly raise SBP and improve perfusion, with repeats every 2–5 minutes to keep the target above about 90. This approach addresses the dual need to improve cardiac output and systemic vascular resistance, stabilizing the patient while monitoring for rhythm changes or hypertension.
