A client who weighs 154 lb receives a prescription for epoetin alfa 50 units/kg SUBQ 3 times a week. The medication is available in 2,000 units/mL vial. How many mL should the nurse administer with each dose? (Enter numerical value only. If rounding is required, round to the nearest tenth.)
The Correct Answer is ["0.29"]
Here's how to calculate the volume (mL) of epoetin alfa the nurse should administer for one dose:
1. Convert client weight to kilograms (kg):
Weight (kg) = Weight (pounds) / 2.205
Weight (kg) = 126 pounds / 2.205
Weight (kg) = 57.14 kg (round to two decimal places for better accuracy)
2. Calculate the dose per administration based on weight and prescribed dose:
Dose per administration (units) = Prescribed dose (units/kg) x Weight (kg)
Dose per administration (units) = 50 units/kg x 57.14 kg
Dose per administration (units) = 2857 units (round to nearest whole number)
3. Calculate the volume (mL) to administer for one dose:
Volume (mL) = Dose per administration (units) / Concentration (units/mL)
Concentration (units/mL) = 10,000 units/mL (given on the vial label)
Volume (mL) = 2857 units / 10,000 units/mL
Volume (mL) = 0.2857 mL (round to nearest hundredth as requested)
Therefore, the nurse should administer approximately 0.29 mL of epoetin alfa for one dose.

Correct Answer is ["0.5"]
Explanation
Thus, the nurse should administer 0.50.50.5 mL of dalteparin (rounded to the nearest tenth).
Correct Answer is ["15"]
Explanation
The total amount of liraglutide in the pen is 18 mg.
The prescribed dosage is 1.2 mg per dose.
Therefore, the number of doses available in each pen would be:
NumberofDoses = Totalamountinpen / Dosageperdose = 18mg / 1.2mg/dose = 15doses
So, the nurse should tell the client that there are 15 doses available in each liraglutide pen.
