MULTIPLE CHOICE

1. Which condition is associated with hydantoin therapy?
a.
Postictal state
b.
Atonia
c.
Seizure threshold reduction
d.
Gingival hyperplasia

ANS: D
Encouraging good oral hygiene practices is indicated when a patient is on hydantoin therapy because its use contributes to gingival hyperplasia. Postictal state is a characteristic of generalized tonic clonic seizures. Atonia is not associated with hydantoin therapy. Hydantoin raises the seizure threshold.

Phenytoin should not be mixed in the same syringe with other medications or added to other intravenous (IV) solutions because a precipitate will form. Phenytoin should be administered slowly at a rate of 25 to 50 mg/min. Patients should be monitored with an ECG closely for bradycardia. Patients should be monitored for hypotension.

Psychotic episodes
c.
Trigeminal neuralgia pain

5. What is the drug of choice when treating a generalized tonic clonic seizure?
a.
Diazepam (Valium)
b.
Haloperidol (Haldol)
c.
Valproic acid (Depakene)
d.
Risperidone (Risperdal)

ANS: C
Anticonvulsant therapy should start with the use of a single agent selected from a group of first line agents based on the type of seizure. Valproic acid is indicated for generalized tonic clonic seizures. Diazepam is not the drug of choice for treatment of tonic clonic seizures. Haloperidol is an antipsychotic medication. Risperidone is an antipsychotic agent.
