What is a common management step for hypovolemia as a reversible cause during arrest?

• A. Establish IV/IO access and administer isotonic crystalloids (e.g., 20 mL/kg bolus) while reassessing
• B. Withhold fluids to avoid edema
• C. Administer diuretics
• D. Initiate high-dose vasopressor alone

Answer: (A)

When hypovolemia causes arrest, the priority is to restore intravascular volume. This means establishing IV or IO access and rapidly delivering isotonic crystalloids, such as a 20 mL/kg bolus, while continuing CPR and reassessing for improved perfusion or ROSC. The fluid bolus increases preload and venous return, helping generate forward blood flow despite the arrest. If there is ongoing bleeding, volume resuscitation remains the first step, with further management as needed. Avoid withholding fluids, diuretics, or relying on vasopressors alone, since they do not fix the underlying volume loss.
