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 ["3"]
Explanation
Here's how to calculate the duration (minutes) for the nurse to administer furosemide:
Prescribed dose: 120 mg furosemide (given)
Recommended rate: 40 mg/minute (given)
We need to find the total time (minutes) required to administer the prescribed dose (120 mg) at the recommended rate (40 mg/minute).
Time (minutes) = Dose (mg) / Rate (mg/minute)
Time (minutes) = 120 mg / 40 mg/minute
Time (minutes) = 3 minutes
Therefore, the nurse should administer the medication over 3 minutes.
Correct Answer is ["0.1"]
Explanation
Here's how to calculate the volume the nurse should administer:
1. Dose of cyanocobalamin (vitamin B12): 100 mcg
2. Concentration of cyanocobalamin in the vial: 1 mg/mL (given on the vial label)
We need to find the volume (in mL) that contains the prescribed dose (100 mcg) of cyanocobalamin.
Calculation:
Volume to administer (mL) = Dose (mcg) / Concentration (mcg/mL)
Note: Since both the medication dose and concentration are given in mcg units, we can directly perform the calculation without converting units.
Volume to administer (mL) = 100 mcg / 1 mg/mL
Conversion:
1 mg is equal to 1000 mcg. Therefore, 1 mg/mL is the same as 1000 mcg/mL.
Volume to administer (mL) = 100 mcg / (1000 mcg/mL)
Volume to administer (mL) = 0.1 mL (round to nearest tenth as requested)
Therefore, the nurse should administer approximately 0.1 mL of the cyanocobalamin injection.
