A nurse preparing to administer epoetin 150 units/kg subcutaneously to a client who weighs 118 lb. Available is epoetin injection 10,000 units/mL. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["0.8"]
Convert the client's weight from pounds to kilograms:
There are 2.205 pounds in 1 kilogram.
118 lb = 118 lb / 2.205 lb/kg = 53.52 kg (rounded to two decimal places).
Determine the total dosage:
The client is prescribed 150 units/kg of epoetin.
The client weighs 53.52 kg.
The total dosage is 150 units/kg x 53.52 kg = 8,028 units.
Calculate the volume per dose:
The epoetin injection contains 10,000 units per mL.
The nurse needs to administer 8,028 units per dose.
To find the volume per dose:
10,000 units / 1 mL = 8,028 units / x mL
10,000x = 8,028
Divide each side by 10,000
x = 0.8028 mL
Round the answer to the nearest tenth:
Rounding 0.8028 to the nearest tenth gives us 0.8 mL.

Correct Answer is ["0.5"]
Explanation
Determine the total dosage:
The client is prescribed 0.175 g of ampicillin/sulbactam.
Convert the dosage to milligrams:
There are 1000 milligrams in 1 gram.
0.175 g = 0.175 x 1000 = 175 mg.
Calculate the volume per dose:
The ampicillin/sulbactam solution contains 375 mg per mL.
The nurse needs to administer 175 mg per dose.
To find the volume per dose:
375 mg / 1 mL = 175 mg / x mL
375x = 175
Dividing both sides by 375, we get:
x = 0.467 mL
Round the answer to the nearest tenth:
Rounding 0.467 to the nearest tenth gives us 0.5 mL.
Correct Answer is ["0.04"]
Explanation
Determine the total dosage:
The client is prescribed 10 mcg of exenatide.
Calculate the volume per dose:
The exenatide solution contains 250 mcg per mL.
The nurse needs to administer 10 mcg per dose.
To find the volume per dose:
250 mcg / 1 mL = 10 mcg / x mL
250x = 10
Dividing both sides by 250, we get:
x = 0.04 mL
