The nursing instructor is preparing to teach nursing students about oppositional defiant disorder (ODD). Which fact should be included in the lesson plan?

A. The diagnosis of ODD often includes refusal to comply with adult's rules or requests: Children with oppositional defiant disorder frequently display persistent defiance, argumentativeness, and refusal to follow directions from authority figures. This behavior is a core diagnostic criterion and is central to the disorder. B. The diagnosis of ODD always includes damaging other people's property on purpose: Deliberate property damage is more characteristic of conduct disorder rather than ODD. While defiance may include spiteful behaviors, property destruction is not required for an ODD diagnosis. C. The diagnosis of ODD occurs before the age of 3: ODD is typically diagnosed in early childhood or school-aged children, but onset is usually after age 3. Symptoms appearing before age 3 are not typically classified as ODD. D. The prevalence of ODD is higher in girls than in boys: ODD is more commonly diagnosed in boys, especially during childhood. Prevalence in girls increases slightly during adolescence, but overall, boys are more frequently affected.
