Final answer:
Restraints in the field of health can only be used when ordered by a licensed healthcare professional, as a last resort, and after other de-escalation techniques have been tried.
Step-by-step explanation:
In the field of health, the use of restraints is only allowed when ordered by a licensed healthcare professional, such as a doctor or nurse. The decision to use restraints is based on the patient's condition and the potential risk to themselves or others. Restraints should only be used as a last resort, after other de-escalation techniques have been tried.
For example, in a hospital setting, restraints may be used on a patient who is at risk of harming themselves or others due to aggression, self-harm, or confusion. The restraints are typically used for a short period of time and are closely monitored by healthcare staff.
