Correct Response: C. According to the National Institutes of Health, among the risk factors for substance abuse is living with parents/guardians who abuse a substance and create an unstable home environment. This can challenge a child's social and psychological development, increasing the child's risk for substance abuse and other negative health behaviors. Living in an urban environment (A) can mean that a child is living in poverty, which is a risk factor, but not a primary risk factor. Being an only child (B) has not been shown to be a risk factor for substance abuse. Having a chronic illness (D) may require a child to take prescription medications that are addictive, which could lead to the abuse of those medications or to the child seeking similar addictive substances that are illegal; however, having a chronic illness is not a primary risk factor for substance abuse.
