Which of the following is NOT a sign of physical abuse?

Regular exercise participation is not a sign of physical abuse because it is a healthy behavior that generally indicates an individual's engagement in physical health and wellness activities. In contrast, internal injuries, skull fractures, and bruises are all common indicators that can result from physical abuse, signaling potential harm inflicted upon an individual. Recognizing the distinction between healthy participation in activities and signs of abuse is crucial in identifying and responding to potential cases of mistreatment. The understanding of these signs aids healthcare professionals in providing appropriate care and intervention when abuse is suspected.
