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 volume (mL) that the nurse should administer, you can use the following formula:
Volume (mL) = Dose (mg)/Concentration (mg/mL)
In this case:
Volume = 300 mg/ (125mg/5 mL)
First, simplify the fraction:
Volume = 300 mg/25 mg/mL
Now, determine the volume:
Volume =(300 mg/25mg/mL) × (1mL/1mg)
Volume=12mL
Therefore, the nurse should administer 12 mL of phenytoin oral suspension for the 300 mg PO dose, rounded to the nearest whole number.
