What type of cell is designated for inmates on suicide watch?

The correct answer is a single cell, which is specifically designated for inmates on suicide watch to ensure their safety and wellbeing. Single cells limit the potential for self-harm by providing a controlled environment where the inmate is monitored closely. This type of placement minimizes opportunities for suicide attempts while allowing officers to observe the inmate more effectively.

In contrast, double cells or group cells do not afford the same level of protection, as sharing a space with another inmate can create risks if either individual exhibits harmful behavior. Isolation cells may imply a punitive measure rather than a preventative approach for mental health concerns, which is counterproductive to the goals of a suicide watch. Thus, the single cell option prioritizes the mental health and safety of the inmate by ensuring they are alone, reducing stimuli and potential risks associated with being housed with others.
