What test should be performed before prescribing a stimulant to a child for ADHD?

• A. Blood pressure
• B. ECG
• C. Height and weight
• D. Behavioral assessment

Answer: (B)

Before prescribing a stimulant for attention-deficit/hyperactivity disorder (ADHD) in children, it is essential to conduct an ECG (electrocardiogram). This test is indicated because stimulants can increase heart rate and blood pressure. Though rare, there have been cases where stimulant medications have been associated with cardiovascular issues, including sudden cardiac events in children with underlying heart conditions that may not be previously diagnosed or known.

While monitoring blood pressure, height, weight, and conducting a behavioral assessment are important components of the overall evaluation and management of a child with ADHD, the ECG specifically addresses the potential cardiovascular risks associated with stimulant therapy, allowing for proactive management of any abnormalities that might be detected. Thus, performing an ECG stands out as a critical safety measure prior to starting stimulant medication in this population.
