Where on the body should you administer an epinephrine injection?

On the person's arm
On the neck
On the person's thigh
On the stomach

The correct answer is: On the person's thigh

The correct administration site for an epinephrine injection is the thigh, specifically the mid-anterolateral thigh. This area is preferred because it has a large muscle mass that ensures better absorption of the medication into the bloodstream. The thigh is also relatively easy to access and provides a safer injection site, reducing the risk of hitting blood vessels or nerves compared to other areas of the body. Using the thigh allows for effective delivery of epinephrine, particularly in emergencies such as severe allergic reactions (anaphylaxis), where quick absorption is critical. This is why most auto-injectors, like EpiPens, are designed for use in the thigh region. Injecting into the arm may not provide as rapid absorption, and using the stomach could be less effective due to variability in absorption rates. Injecting into the neck might pose a higher risk of injury or complications. Therefore, the thigh is recognized as the safest and most effective site for an epinephrine injection in emergency situations.
