Initial management of circulatory shock includes which action?

• A. Start vasopressors immediately
• B. Provide oxygen therapy only
• C. Place in Trendelenburg position
• D. Give IV fluids

Answer: (D)

In circulatory shock, the quickest way to improve tissue perfusion is to restore the circulating volume. Administering isotonic IV fluids increases venous return (preload), which can raise stroke volume and blood pressure, helping to reestablish adequate perfusion in many shock states. This volume expansion addresses the foundational problem of underfilling that often drives shock, making it the best initial step.

Vasopressors are important if hypotension persists after fluids or if shock is primarily vasodilatory or cardiogenic, but starting them right away without first restoring volume can worsen perfusion when the patient is volume depleted. Oxygen therapy supports delivery, but it does not fix the underlying circulatory deficit by itself. The Trendelenburg position is not recommended—it can impair breathing and hasn’t shown benefits in improving outcomes.
