What is the dosing requirement of epinephrine for anaphylaxis treatment?

1. 0.005mg/kg with a maximum of 0.25mg

2. 0.01mg/kg with a maximum of 0.5mg

3. 0.02mg/kg with a maximum of 1mg

Option C (0.02mg/kg with a maximum of 1mg) is incorrect because it is a higher dose than the recommended 0.01mg/kg, which may increase the risk of side effects and adverse reactions. Option D (0.03mg/kg with a maximum of 2mg) is incorrect because it is an even higher dose than the incorrect option C, increasing the risk of
