Calculation
The healthcare provider prescribes epinephrine 0.01 mg/kg IM for an adolescent with an acute asthma episode who weighs 110 pounds. The available medication is labeled 1 mg/mL. Based on the client's weight, how many mL should the nurse administer to this client? (Enter numerical value only, rounded to the nearest tenth.)
mL
