2. A patient who has epilepsy will begin an anticonvulsant medication. The patient asks the
nurse how long the medication will be necessary. How will the nurse respond? a. The
medication is usually taken for a lifetime.

c. You will need to take the medication for 3 to 5 years.
d. You will take the medication as needed for seizure activity.
ANS: A
Anticonvulsants are given to prevent seizures and are usually taken throughout the patients

patients may attempt to stop taking the medications after 3 to 5 years of no seizure activity.
Anticonvulsants are not given as needed.

Hydantoins commonly cause gingival hyperplasia, which causes overgrowth of reddened gum
tissue that bleeds easily. It is not a sign of a drug interaction or a symptom of hepatotoxicity.
It does not indicate a lack of self-care.

a. Administer the dose since the patient is not toxic.
b. Contact the provider to discuss decreasing the phenytoin dose.

drug level is normal, since 10-20 mcg/mL is the therapeutic range. The nurse should
administer the dose. It is not necessary to decrease the dose or monitor the patient more
closely than usual.
