The client is prescribed phenytoin suspension 250 mg, po three times per day. The strength of the drug is 125 mg/5mL. How many mL will the nurse administer at each dose? Round to the nearest whole number
What will be an ideal response?
10 mL/dose
Global Rationale: mL/dose = 5mL/125 mg x 250 mg/1 dose. Multiply the numerators (5 x 250 = 1250). Multiply the denominators (125 x 1 = 125). 1250/125= 10 mL/dose.
