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.)
The Correct Answer is ["0.5"]
here's how to calculate the volume (mL) of epinephrine the nurse should administer:
1. Client weight conversion:
Client weight: 110 pounds
Since medication dosage is based on weight per kilogram (kg), we need to convert the weight to kg for accurate calculation.
Conversion factor: 1 kg = 2.205 lbs
Client weight (kg) = 110 pounds / 2.205 lbs/kg
Client weight (kg) = 50 kg (round to nearest whole number)
2. Epinephrine dosage:
Prescribed dose: 0.01 mg/kg (given)
3. Epinephrine concentration:
The medication is labeled 1 mg/mL. This indicates there are 1 mg of epinephrine per 1 mL of solution.
4. We need to find the volume (mL) containing the prescribed dose (based on weight) of epinephrine (0.01 mg/kg) considering the concentration (1 mg/mL) in the vial.
Total epinephrine dose (mg): Dose (mg/kg) x Client weight (kg)
Total epinephrine dose (mg): 0.01 mg/kg * 50 kg
Total epinephrine dose (mg): 0.5 mg (round to nearest tenth)
Volume to administer (mL): Total dose (mg) / Concentration (mg/mL)
Volume to administer (mL): 0.5 mg / 1 mg/mL
Volume to administer (mL): 0.5 mL (round to nearest tenth)
Therefore, the nurse should administer approximately 0.5 mL of epinephrine intramuscularly.

Correct Answer is ["0.8"]
Explanation
Here's how to calculate the volume (mL) of epoetin alfa the nurse should administer:
1. We know the following:
Prescribed dose: 8,200 units epoetin alfa (given)
Vial concentration: 10,000 units/mL (given from the label)
2. We need to find the volume (mL) to administer for the prescribed dose (8,200 units) considering the concentration (10,000 units/mL).
Volume to administer (mL) = Dose (units) / Concentration (units/mL)
Volume to administer (mL) = 8,200 units / 10,000 units/mL
Volume to administer (mL) = 0.82 mL (round to nearest tenth)
Therefore, the nurse should administer 0.8 mL of epoetin alfa subcutaneously.
Correct Answer is ["0.4"]
Explanation
here's how to calculate the volume (mL) of ketorolac the nurse should administer:
1. Dose of ketorolac to administer:
Dose = 12 mg (given)
2. Concentration of ketorolac in the vial:
Concentration = 30 mg/mL (given)
3. We need to find the volume (mL) containing the prescribed dose (12 mg) considering the concentration (30 mg/mL) in the vial.
Volume to administer (mL): Dose (mg) / Concentration (mg/mL)
Volume to administer (mL): 12 mg / 30 mg/mL
Volume to administer (mL) = 0.4 mL (round to nearest tenth)
Therefore, the nurse should administer approximately 0.4 mL of ketorolac intravenously.
