A client is receiving phenytoin 0.2 gram PO twice daily. The medication is available in 100 mg capsules. How many capsules should the nurse administer? (Enter numeric value only.)

Calculation: Desired dose = 0.2 gram Available dose per capsule = 100 mg per capsule Ensure the units are the same: Convert grams to milligrams: 0.2 g x 1000 mg/g = 200 mg Calculate the number of capsules: Number of capsules = Desired dose (mg) / Available dose per capsule (mg/capsule) = 200 mg / 100 mg/capsule = 2 capsules
