What is a typical intravenous bolus dose of epinephrine?

• A. 10 mcg
• B. 1 mg
• C. 100 mcg
• D. 0.1 mcg

Answer: (A)

Epinephrine dosing in acute care is often given as small, titratable IV boluses to quickly improve hemodynamics. A low, testable dose leverages the drug’s beta1 effects (to boost heart rate and contractility) with a modest alpha effect to raise blood pressure, without provoking excessive vasoconstriction or arrhythmias. Ten micrograms is the typical IV bolus amount because it’s large enough to produce a meaningful pressor and inotropic response, yet small enough to allow careful titration and minimize side effects. A dose as small as 0.1 microgram would likely be too small to matter in an emergent setting. A dose of 100 micrograms would cause a stronger vasoconstrictive spike, increasing risk of ischemia and tachyarrhythmias. The 1 mg dose is the standard IV push used during cardiac arrest (ACLS resuscitation), not a routine bolus for shock or hypotension management.
