Methylphenidate is used cautiously in which child scenario?

• A. An 8-year-old client with a history of cardiovascular disease.
• B. A 6-year-old with asthma.
• C. A 7-year-old with obesity.
• D. A 5-year-old with eczema.

Answer: (A)

Methylphenidate is a CNS stimulant that can raise heart rate and blood pressure and, in some cases, trigger cardiac rhythm changes. Because of these cardiovascular effects, it’s used cautiously in children who have cardiovascular disease, since their heart condition can be worsened by the stimulant. In such cases clinicians may require careful monitoring, baseline and follow-up vitals or ECG, and may consider alternative treatments if the risks outweigh the benefits.

The other scenarios don’t involve a cardiovascular risk, so they aren’t the primary reason for caution. Asthma isn’t a contraindication, though monitoring is still wise; obesity and eczema don’t directly restrict stimulant use, though growth and skin health should be watched as part of overall care.
