Answer to Question 1
C
Valproic acid is given initially at a dose of 5 to 15 mg/kg/day, administered in two divided doses. This child is receiving 400 mg/day, which is 10 mg/kg/day. The dosage should be increased by 5 to 10 mg/kg/day each week until optimal levels are achieved up to a maximum dose of 60 mg/kg/day. At this point, adding another AED or changing to another AED is not recommended. Increasing the dose to three times daily is not recommended.
Answer to Question 2
C
One of the principal effects of angiotensin-converting enzyme (ACE) inhibitors is hyperkalemia, which is due to decreased aldosterone release arising from blockage of angiotensin II. There is no indication that careful monitoring of sodium for increased levels is indicated. Vasotec is indi-cated for heart failure, not hypertension. The drug therapy should be monitored to ascertain its effectiveness, but hyperkalemia is the main concern. Hyperkalemia, not hypokalemia, is a concern because of the decreased aldosterone release that occurs with blockage of angiotensin II.
