MULTIPLE CHOICE

 

1. The nurse is reviewing the dosage schedule for several different antiepileptic drugs (AEDs). Which antiepileptic drug allows for once-a-day dosing?

a.	Levetiracetam (Keppra)
b.	Phenobarbital
c.	Valproic acid (Depakote)

Phenobarbital has the longest half-life of all standard AEDs, including those listed in the other options, so it allows for once-a-day dosing.

2. The nurse has given medication instructions to a patient receiving phenytoin (Dilantin). Which statement by the patient indicates that the patient has an adequate understanding of the instructions?

a.	“I will need to take extra care of my teeth and gums while on this medication.”
b.	“I can go out for a beer while on this medication.”
c.	“I can skip doses if the side effects bother me.”
d.	“I will be able to stop taking this drug once the seizures stop.”

 

 

ANS:  A

Scrupulous dental care is necessary to prevent gingival hypertrophy during therapy with phenytoin. Alcohol and other central nervous system depressants may cause severe sedation. Consistent dosing is important to maintain therapeutic drug levels. Therapy with AEDs usually must continue for life and must not be stopped once seizures stop.

3. When teaching a patient about taking a newly prescribed antiepileptic drug (AED) at home, the nurse will include which instruction?

a.	“Driving is allowed after 2 weeks of therapy.”
b.	“If seizures recur, take a double dose of the medication.”
c.	“Antacids can be taken with the AED to reduce gastrointestinal adverse effects.”
d.	“Regular, consistent dosing is important for successful treatment.”

 

 

ANS:  D

Consistent dosing, taken regularly at the same time of day, at the recommended dose, and with meals to reduce the common gastrointestinal adverse effects, is the key to successful management of seizures when taking AEDs. Noncompliance is the factor most likely to lead to treatment failure.

4. A patient has a 9-year history of a seizure disorder that has been managed well with oral phenytoin (Dilantin) therapy. He is to be NPO (consume nothing by mouth) for surgery in the morning. What will the nurse do about his morning dose of phenytoin?

a.	Give the same dose intravenously.
b.	Give the morning dose with a small sip of water.
c.	Contact the prescriber for another dosage form of the medication.
d.	Notify the operating room that the medication has been withheld.

 

 

ANS:  C

If there are any questions about the medication order or the medication prescribed, contact the prescriber immediately for clarification and for an order of the appropriate dose form of the medication. Do not change the route without the prescriber’s order. There is an increased risk of seizure activity if one or more doses of the AED are missed.
