Answer to Question 1

D
Geriatric patients may need adjusted doses based on creatinine clearance testing, so obtaining a creatinine clearance test before initiating therapy is indicated. LFTs, coagulation studies, and an ECG are not indicated.

Answer to Question 2

A
Valproic acid may cause thrombocytopenia and inhibition of platelet aggregation. Platelet counts and coagulation studies should be done before therapy is initiated, at regular intervals, and before any surgical procedure is performed.
