Final answer:
The dietitian's intervention for a child with ADHD being treated with methylphenidate should be based on an understanding that anorexia and involuntary weight gain can be potential adverse effects. Folate supplements are not usually warranted in this context.
Step-by-step explanation:
The dietitian's intervention for a child with attention deficit hyperactivity disorder (ADHD) who is being treated with methylphenidate should be based on an understanding that:
- Anorexia can be an adverse effect that may affect growth. Methylphenidate, the medication used to treat ADHD, can decrease appetite and potentially lead to weight loss or poor weight gain in some children.
- Involuntary weight gain can be a likely adverse effect. While it is not common, some children treated with methylphenidate may experience weight gain.
- Folate supplements usually are not warranted to counter increased urinary excretion. Folate supplements are not typically recommended specifically for children with ADHD who are being treated with methylphenidate.
