A nurse is preparing to administer phenytoin 50 mg IV bolus to a client Who has a seizure disorder. The medication is supplied as a 50 mg/mL vial. Which of the following actions should the nurse take?

Dilute the medication with sterile water before injecting.

Administer the medication over 1 min.

Follow the IV injection with sterile water.

Slow the injection if the medication crystallizes.

Answer and Explanation

The Correct Answer is B

A.   Diluting phenytoin with sterile water before injecting is not recommended, as phenytoin is incompatible with most used diluents. Diluting it can lead to precipitation and potentially cause adverse effects such as tissue irritation and phlebitis.
B.   Administering the medication over 1 min is recommended. Phenytoin should be administered at a rate of 50mg/min.
C.   Following the IV injection with sterile water is unnecessary and not indicated for administering phenytoin.
D. Phenytoin precipitates out of solution when mixed with certain diluents or when administered too quickly. Crystallized phenytoin can cause local irritation, tissue damage, and potentially more serious adverse effects. Therefore, it should not be administered at all.
