ATI PN Dosage Calculations. Adult medical surgical proctored assessment 3.1 ( 25 Questions)
A nurse is preparing to administer phenytoin 300 mg PO every 12 hr to a client who has a seizure disorder. Available is phenytoin oral suspension 125 mg/5 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.)
To calculate the dose of phenytoin oral suspension for a client with a seizure disorder, the nurse needs to use the following formula:
Dose (mL) = Ordered dose (mg) / Concentration (mg/mL)
In this case, the ordered dose is 300 mg and the concentration is 125 mg/5 mL. Therefore, the dose in mL is:
Dose (mL) = 300 mg / (125 mg/5 mL)
Dose (mL) = 300 mg x (5 mL/125 mg)
Dose (mL) = 12 mL
The nurse should round the answer to the nearest whole number, which is 12 mL. The nurse should administer 12 mL of phenytoin oral suspension every 12 hours to the client.
