Which of the following is considered an example of physical abuse?

Pulling a child's hair is categorized as physical abuse because it involves direct physical action that can cause harm or injury to a child. Physical abuse encompasses any act where a caregiver intentionally inflicts physical harm, either through violent actions or inappropriate physical discipline. This can include behaviors that result in pain or bodily injury, and pulling hair falls squarely within that category as it may lead to physical discomfort and emotional distress for the child.

The other options focus on different aspects of possible abuse or neglect, such as emotional or neglectful situations, rather than direct physical harm. For instance, begging for or stealing food might indicate food insecurity or neglect rather than active physical abuse. Difficulty in walking or sitting can be a sign of physical injury or emotional abuse but does not directly denote the act of physical abuse on its own. Lastly, unattended medical needs highlight issues of neglect regarding proper care, rather than acts of physical aggression or harm.
