What is true regarding epinephrine?

Question

Quizplus · Accepted Answer

Research has shown that epinephrine administered IM in the vastus lateralis absorbs quicker than if given IM in the deltoid or subcutaneously in the arm. If ordered, repeat every 5 to 10 minutes. Do not administer repeated injections in the same site since vasoconstriction may cause tissue necrosis. The typical dose epinephrine injectable solution (of 1 mg/mL) for anaphylaxis is:
• Children and adults (66 lb. [30 kg] or more): 0.3 to 0.5 mg (0.3 to 0.5 mL)
• Children (under 66 lb. [30 kg]): 0.01 mg/kg (0.01 mL/kg) with a maximum dose per injection is 0.3 mL
