The nurse receives the primary provider's order of phenytoin 0.2 g orally twice daily. The medication label states that each capsule is 100 mg. The nurse prepares how many capsule(s) to administer. (Round to the nearest whole number)
20
0.2
2
200
The Correct Answer is C
A. 20: Incorrect, as it would imply a much higher dose.
B. 0.2: Incorrect, as this would be far too low.
C. 2: Phenytoin 0.2 g is equivalent to 200 mg (0.2 g x 1000 mg/g). Since each capsule is 100 mg, the nurse would need to administer 2 capsules (200 mg / 100 mg per capsule = 2).
D. 200: Incorrect, as 200 capsules would be an overdose.
