Which of the following actions constitutes physical abuse?

The action that constitutes physical abuse is slapping a detainee intentionally. Physical abuse is defined as any form of bodily harm inflicted upon an individual, and intentionally slapping someone falls squarely within this definition. It inflicts pain and can cause both physical and psychological trauma, which is a serious violation of ethical standards and human rights.

In contrast, offering medication, providing recreational activities, and sharing food with detainees are actions that are generally intended to promote well-being, health, and decent treatment. They are aligned with the principles of care and respect for human dignity, which are fundamental in medical ethics and detainee operations. These actions demonstrate a commitment to the welfare of the detainees rather than causing harm, making them ethical and acceptable practices in a detention setting.
