Correct Answer is D
Explanation
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.
Correct Answer is C
Explanation
A. Soft restraints are not recommended during a seizure and can cause harm to the patient.
B. Placing anything in the mouth during a seizure can lead to injury or airway obstruction and is contraindicated.
C. Turning the patient on their side helps to maintain an open airway and prevent aspiration; staying with the patient ensures ongoing monitoring.
D. Leaving the patient alone to seek help is unsafe, as it leaves the patient unmonitored during the seizure.
