Hesi Medical Dosage Calculation
Hesi Medical Dosage Calculation ( 53 Questions)
A client who weighs 154 pounds receives a prescription for epoetin alfa 50 units/kg subcutaneously 3 times a week. The medication is available in 2000 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.)
To find out how many mL of epoetin alfa to administer, you need to first convert the client's weight from pounds to kilograms by dividing by 2.2.
Then, you need to use the formula: D/H x Q = X, where D is the desired dose, H is the dose on hand, Q is the quantity on hand, and X is the amount to give. In this case, D = 50 units/kg x client's weight in kg, H = 2000 units/mL, Q = 1 mL, and X is unknown. Plug in the values and solve for X:
Client's weight in kg = 154 pounds / 2.2
Client's weight in kg = 70 kg
D = 50 units/kg x 70 kg
D = 3500 units
X = (3500 units / 2000 units/mL) x 1 mL
X = 1.745 mL
Therefore, the nurse should administer 1.7 mL of epoetin alfa (rounded off to the nearest tenth)
