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.)
The Correct Answer is ["2"]
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

Correct Answer is ["105"]
Explanation
Calculation:
Convert the infant's weight from grams to kilograms:
Weight (kg) = Weight (grams) / 1000 grams/kg
= 3500 grams / 1000 grams/kg
= 3.5 kg
Calculate the total daily dose in milligrams:
Daily dose (mg) = Prescribed dose (mg/kg/day) x Infant's weight (kg)
= 30 mg/kg/day x 3.5 kg
= 105 mg/day
Correct Answer is ["2"]
Explanation
Calculation:
Prescribed dose = 40 mg
Available dose per capsule = 20 mg/capsule
Calculate the number of capsules to administer:
Number of capsules = Prescribed dose / Available dose per capsule
= 40 mg / 20 mg/capsule
= 2 capsules
