The healthcare provider prescribes cyanocobalamin injection 100 mcg IM every 3 days for a client with pernicious anemia. The vial is labeled, "1 mg/mL." How many mL should the nurse administer? (Enter numerical value only. If rounding is required, round to the nearest tenth.)
The Correct Answer is ["0.1"]
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.

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 ["1.8"]
Explanation
Here's how to calculate the volume (mL) of diazepam the nurse should administer:
Calculate the total dose of diazepam for the child:
Dose per kg: 0.3 mg/kg (given)
Child's weight: 30 kg (given)
Total dose (mg) = Dose per kg (mg/kg) x Child's weight (kg)
Total dose (mg) = 0.3 mg/kg * 30 kg
Total dose (mg) = 9 mg (round to nearest whole number)
Concentration of the medication:
The medication is available in 5 mg/mL vials (given).
Calculate the volume to administer:
Volume to administer (mL) = Total dose (mg) / Concentration (mg/mL)
Volume to administer (mL) = 9 mg / 5 mg/mL
Volume to administer (mL) = 1.8 mL (round to nearest tenth)
Therefore, the nurse should administer approximately 1.8 mL of diazepam intravenously.
