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 ["125"]
Explanation
Determine the total volume to be administered:
The client is to receive 500 mL of lactated Ringer's IV.
Calculate the time to administer the volume:
The medication is to be administered over 4 hours.
Calculate the flow rate:
To find the flow rate in mL/hr, we can divide the total volume by the time:
Flow rate (mL/hr) = Total volume (mL) / Time (hr)
Flow rate = 500 mL / 4 hr= 125 mL/hr
Correct Answer is ["4"]
Explanation
Determine the total daily dosage:
The client is prescribed 400,000 units of nystatin every 6 hours.
There are 24 hours in a day, so the medication is given 24/6 = 4 times a day.
Total daily dosage is 400,000 units/dose x 4 doses = 1,600,000 units per day.
Calculate the dosage per dose:
The medication is to be administered in divided doses every 6 hours.
There are 24 hours in a day, so the medication is given 24/6 = 4 times a day.
Dosage per dose is 1,600,000 units / 4 doses = 400,000 units per dose.
Determine the number of mL per dose:
The nystatin oral suspension contains 100,000 units per mL.
The nurse needs to administer 400,000 units per dose.
Divide 400,000 units / 100,000 units per mL = 4 mL per dose.
