What is the appropriate action for a nurse administering phenytoin IV?

When administering phenytoin intravenously, the appropriate action is to administer a saline solution after the injection. This practice is crucial because phenytoin has a tendency to precipitate in the presence of certain solutions or if left in the vein without flushing. By administering a saline flush post-injection, the nurse can ensure that the medication is fully delivered into the bloodstream and reduce the risk of irritation or extrusion from the intravenous site, which can occur if the drug remains concentrated in a localized area of the vascular system.

Additionally, flushing with saline helps clear the catheter, ensuring that there is no residual phenytoin left that could potentially irritate the vein. This practice is standard in IV medication administration, especially for medications like phenytoin, which require specific handling to maintain efficacy and patient safety.

Monitoring the patient after administration is also important; however, the immediate action post-injection should be focused on ensuring proper flush with saline to enhance drug delivery and minimize potential complications.
