Question

After an adolescent diagnosed with attention deficit-hyperactivity disorder (ADHD) begins methylphenidate (Ritalin) therapy, a nurse notes that the adolescent loses 10 pounds in a 2-month period. What is the best explanation for this weight loss?

1) The pharmacological action of Ritalin causes a decrease in appetite.
2) Hyperactivity seen in ADHD causes increased caloric expenditure.
3) Side effects of Ritalin cause nausea; therefore, caloric intake is decreased.
4) Increased ability to concentrate allows the client to focus on activities rather than food.

Answer 1

The adolescent's weight loss after starting methylphenidate therapy, commonly known as Ritalin, can be attributed to the medication's side effect of decreased appetite.

Step-by-step explanation:

The best explanation for the weight loss the adolescent experienced after beginning methylphenidate (Ritalin) therapy is most likely due to decreased appetite, which is a known pharmacological action of the drug. Methylphenidate is a stimulant medication often utilized in the treatment of ADHD. It increases neurotransmitter activity within the brain, notably in areas associated with impulse control. One of the therapeutic effects at the dosages prescribed for ADHD management includes decreased appetite.
