Final answer:
A patient with well-controlled focal seizures on phenytoin and mild gingival hyperplasia should maintain regular dental check-ups, perform daily gum massages, and practice good oral hygiene. It is not advised to avoid dental visits.
Step-by-step explanation:
The instructions a nurse should give to a patient who has focal seizures well controlled with phenytoin and who has mild gingival hyperplasia include:
- Maintain regular dental check-ups to monitor the health of the gums and teeth.
- Perform daily gum massage to stimulate circulation and help reduce gingival hyperplasia.
- Practice good oral hygiene including brushing and flossing to prevent plaque build-up which can exacerbate gum issues.
Avoiding dental visits is not recommended as professional care is necessary to address and monitor complications such as gingival hyperplasia.
