A nurse is preparing to administer phenytoin 100 mg PO every 8 hours.
If the available phenytoin suspension is 125 mg/5 mL, how many mL should the nurse administer per dose?
The Correct Answer is ["4 "]
Step 1 is to calculate the volume of phenytoin to administer. Given that the available phenytoin suspension is 125 mg/5 mL and the nurse needs to administer 100 mg, the calculation is as follows: 100 mg ÷ (125 mg/5 mL) = 4 mL
