Explanation:

Identify standard adult epinephrine auto-injector dosage

Using the Anaphylaxis Management and Epinephrine Indications knowledge points

• Epinephrine auto-injectors (such as EpiPen) are pre-measured, single-dose devices used for the emergency treatment of severe allergic reactions (anaphylaxis).
• The standard adult auto-injector delivers a dose of \(0.3\text{ mg}\) of epinephrine (concentration \(1:1000\) intramuscularly).
• The pediatric auto-injector (EpiPen Jr.) delivers a dose of \(0.15\text{ mg}\) for patients weighing between \(15\text{ kg}\) and \(30\text{ kg}\).
• Therefore, the standard adult dose is \(0.3\text{ mg}\).

Answer:

• (A) 0.15 mg.
• (B) 0.3 mg. (Correct answer)
• (C) 0.5 mg.
• (D) 1.0 mg.
