What is the recommended IV fluid bolus for hypotension?

• A. 0.9% NaCl 1-2 L, reassess every 250 mL
• B. 2-3 L bolus
• C. 100 mL
• D. No IV fluids

Answer: (A)

When someone is hypotensive, the immediate goal is to restore circulating volume quickly using an isotonic crystalloid, because it expands the intravascular space and improves preload and perfusion. A moderate normal saline bolus is given and the patient is reassessed after each small increment to gauge response and avoid fluid overload. This titration approach—start with a clinically reasonable volume and adjust based on how the patient responds—balances correcting hypotension with the risk of overloading the circulation. Larger single boluses can push fluids too far before you see benefit, tiny ones may not raise blood pressure effectively, and giving no fluids delays needed resuscitation. If perfusion remains inadequate after volume resuscitation, further evaluation and escalation (such as vasopressors) are warranted.
