What route is used for epinephrine dosing in this protocol?

• A. Intramuscular
• B. Intravenous
• C. Oral
• D. Subcutaneous

Answer: (A)

In emergency anaphylaxis treatment, the goal is rapid and reliable onset, so the dosing route is chosen for quick absorption. Intramuscular injection delivers epinephrine into muscle tissue, where it is absorbed quickly and predictably, producing a fast therapeutic effect needed to reverse airway swelling, bronchospasm, and hypotension. Intravenous administration carries higher risk in the field and requires close monitoring and titration, which is not typically appropriate for EMT practice. Oral administration is ineffective in this context due to poor absorption and slow onset. Subcutaneous injections can be slower and more variable in absorption, especially in a patient who is distressed or in shock. Therefore, the preferred route for epinephrine dosing in this protocol is intramuscular.
