A nurse is preparing to administer nystatin 400,000 units PO every 6 hr. Available is nystatin oral suspension 100,000 units/mL. How many mL should the nurse administer per dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["4"]
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.
