Answer to Question 1

ANS: A

Feedback
A Correct: Fosphenytoin sodium is the drug of choice, because it is rapidly converted to phenytoin and does not cause the high irritability associated with parenteral phenytoin.
B Incorrect: This is an oral anticonvulsant.
C Incorrect: This is an oral anticonvulsant.
D Incorrect: This is an oral anticonvulsant.

Answer to Question 2

ANS: C

Feedback
A Incorrect: This is a normal platelet count; phenytoin normally does not affect platelets.
B Incorrect: This is less than a therapeutic level, but manifestations should involve seizure activity.
C Correct: These are manifestations of phenytoin toxicity and this is a toxic phenytoin level.
D Incorrect: This is a normal sodium level; phenytoin normally does not affect sodium level.
