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.)
Explanation & Rationale
Here's how to calculate the volume (mL) of epinephrine the nurse should administer: 1. Convert the client's weight from pounds to kilograms: Weight (kg) = Weight (lb) / 2.2 Weight (kg) = 110 lb / 2.2 Weight (kg) = 50 kg (approximately) 2. Calculate the total epinephrine dose based on weight and prescribed dosage: Dose (mg) = Dose (mg/kg) x Weight (kg) Dose (mg) = 0.01 mg/kg x 50 kg Dose (mg) = 0.5 mg 3. Determine the volume (mL) to administer considering the medication concentration: Concentration (mg/mL) = 1 mg/mL (given from the medication label) Volume (mL) = Dose (mg) / Concentration (mg/mL) Volume (mL) = 0.5 mg / 1 mg/mL Volume (mL) = 0.5 mL (already rounded to the nearest tenth) Therefore, the nurse should administer 0.5 mL of epinephrine intramuscularly.
