Final answer:
Jack and his parents should be informed about the potential side effects of methylphenidate (Ritalin), which can include irritability, cognitive impairment, and memory issues among others.
Step-by-step explanation:
Jack, age 8, has attention deficit disorder (ADD) and is prescribed methylphenidate (Ritalin). Jack and his parents should be educated about the side effects of methylphenidate, which include irritability, cognitive impairment, memory lapses or loss, impaired moral judgment, severe yawning, hallucinations, and symptoms similar to ADHD. Methylphenidate is a stimulant drug used to treat ADHD, characterized by difficulty maintaining attention and controlling impulses. While the therapeutic effects at proper doses can lead to increased focus and decreased impulsivity, side effects are possible, and it is important for Jack and his parents to be informed of these potential reactions.
