A child will begin taking methylphenidate (Ritalin) for attention-deficit/hyperactivity disorder. Important baseline information about this patient will include:
a. results of an electrocardiogram (ECG).
b. family history of psychosis.
c. height and weight.
d. renal function.
ANS: C
Side effects of methylphenidate include a reduced appetite, and children taking these drugs should be monitored for growth suppression. Baseline height and weight measurements help with this ongoing assessment. The value of an ECG for children has not been proven, except when known heart disease is a factor. Excessive use of stimulants can produce a state of psychosis but is not related to the family history. Renal function tests are not indicated.
