Final answer:
The correct statement about epinephrine administration via IM is that the 1:1000 concentration should be used, preferably injected into the anterolateral aspect of the thigh, not the upper arm. The IM route is suitable for children, and the maximum single adult dose is usually 0.3 to 0.5 mg, contrary to the 0.15 mg cited.
Step-by-step explanation:
The correct statement regarding epinephrine administration via the intramuscular (IM) route is: 1) The 1:1000 concentration should be used. This concentration is used for IM injection for treating anaphylaxis. The preferred site of injection is not the upper arm, but rather the anterolateral aspect of the thigh. This is because the thigh muscle provides a large area for absorption and is less painful compared to other areas.
It is incorrect to say that the IM route should not be used in children. In fact, epinephrine via IM injection is the recommended route for children experiencing a severe allergic reaction. Additionally, the maximum single adult dose is not 0.15 mg, but commonly 0.3 to 0.5 mg for adults. Children commonly receive a dose of 0.15 mg if they are using auto-injectable devices like an EpiPen, which have dosages adjusted for different age groups and body weights.
