Exhibits The healthcare provider comes to the bedside following the seizure and prescribes phenytoin. The nurse administers the phenytoin as prescribed. Which possible side effect(s) of phenytoin should the nurse assess for after administration? Select all that apply.

A. Vomiting is not a common side effect of phenytoin but could occur in some patients. It’s more likely a reaction to the medication rather than a frequent side effect. B. Phenytoin can affect blood coagulation. It may interfere with vitamin K metabolism, which can alter coagulation pathways and increase the risk of bleeding or bruising. Monitoring for signs of bleeding or changes in clotting status is important, particularly in patients on long-term therapy. C. Visual disturbances, including nystagmus (involuntary eye movements), double vision, or blurred vision, can occur with phenytoin use. This side effect is related to the medication’s impact on the nervous system. D. Drowsiness is a common side effect of many antiepileptic drugs, including phenytoin. It can affect the client’s alertness and overall level of consciousness, making it important for the nurse to monitor and address any related safety concerns. E. Aphasia, or difficulty with language and speech, is not a typical side effect of phenytoin. While phenytoin affects the central nervous system, aphasia is not commonly reported with its use. F. Ataxia, or lack of coordination and unsteady movements, is a known side effect of phenytoin. This occurs due to its effects on the nervous system and can impair motor skills and coordination.
