The adult epinephrine auto-injector delivers ______ mg of epinephrine, and the infant-child auto-injector delivers ______ mg.

• A. 0.1; 0.01
• B. 0.03; 0.3
• C. 0.01; 0.1
• D. 0.3; 0.15

Answer: (D)

Dosing for epinephrine auto-injectors comes in two standard strengths to match body size: a higher dose for adults and a lower dose for children. The adult device delivers 0.3 mg of epinephrine, while the infant-child device delivers 0.15 mg. This weight-based approach helps ensure the drug is effective enough to counter anaphylaxis without causing excessive side effects in smaller patients. So the pairing of 0.3 mg for adults and 0.15 mg for infant-child is the correct combination. Other options mix doses that aren’t aligned with the standard auto-injector strengths.
