Which medication-dose pairing is correctly matched for an adult patient?

• A. Midazolam 10 mg IM
• B. Narcan 0.4 mg IV
• C. Benadryl 25 mg IM
• D. Epinephrine 0.3 mg IM

Answer: (A)

The key idea here is that adult medication dosing in EMS is about matching a practical, commonly used single-dose amount to a typical emergency scenario, with attention to route and onset. Midazolam given at 10 mg intramuscularly is a classic single-dose option for adults when rapid effect is needed and IV access isn’t yet established. This 10 mg IM dose sits at the widely accepted maximum single dose for an adult, providing quick sedation or seizure control with a clear plan to monitor airway and respiration. That makes it a clean, correctly matched pairing for an adult in many EMS protocols. The other options involve dosing or routes that aren’t as consistently aligned with standard adult EMS practice. Naloxone is often titrated and can be given by different routes (IM, IV, IN) with variable starting doses; diphenhydramine at 25 mg IM is commonly undersized for adults who present with allergic reactions, where a higher dose like 50 mg is typical; epinephrine at 0.3 mg IM is indeed a standard dose for anaphylaxis, but without more context, it isn’t as universally “the correct single-dose pairing” as the maximum 10 mg IM benzodiazepine option.
