For non-trauma related shock, what is the fluid resuscitation dose?

• A. 20 mL/kg IV/IO; may repeat x2 with no rales on lung exam
• B. 10 mL/kg IV; may repeat x1
• C. 30 mL/kg IV/IO; may repeat x2
• D. 5 mL/kg IV/IO

Answer: (A)

In non-traumatic shock, the goal is to rapidly restore intravascular volume while watching for signs of fluid overload. The standard initial bolus is 20 mL/kg given IV or IO. After each bolus, reassess perfusion, mental status, urine output, and lung sounds. If there are no signs of edema (no rales on lung exam), a second bolus may be given, and you can repeat up to two times in total if needed. Stop fluids if crackles or other signs of pulmonary edema appear. This approach provides prompt volume expansion without overdoing it, since smaller amounts may be too slow to correct shock and larger amounts (like 30 mL/kg) are used in different contexts or trauma protocols.
