The nurse is caring for a patient who was given a new medical prescription for phenytoin. What would the nurse stress in the discharge instructions regarding this medication?
"Use a cane or walker when you begin to have difficulty walking."
"Adjust the dose depending upon observed seizure activity."
"You will need to have blood levels drawn annually."
"Be sure to have regular visits to the dentist."
The Correct Answer is D
A. While using a cane or walker may be necessary for some patients experiencing balance issues, it is not a specific instruction related to phenytoin.
B. Phenytoin dosages should not be adjusted solely based on observed seizure activity; the dose must be managed carefully based on serum drug levels and the clinician's guidance.
C. Patients on phenytoin typically require more frequent monitoring of blood levels (every 2-3 months initially) rather than annually, as maintaining therapeutic levels is essential to avoid toxicity or ineffective seizure control.
D. Regular dental visits are crucial for patients taking phenytoin because the medication can cause gingival hyperplasia (overgrowth of gum tissue), which necessitates careful dental hygiene and regular monitoring by a dentist to prevent complications.
