Answer to Question 1

A
A phenytoin plasma level above 20 mcg/mL may cause the patient to manifest nystagmus and diplopia, as well as other signs of toxicity. This level is toxic; the normal level is 10 to 20 mcg/mL.
Nystagmus and diplopia are not indications of an impending seizure.
No evidence suggests that Stevens-Johnson syndrome is a factor.
Gingival hyperplasia is not a result of toxicity, but rather an expected effect in about 20 of pa-tients given phenytoin.
