Final answer:

Step-by-step explanation:
The use of restraints on individuals who are 18 years or older is generally governed by a complex mix of laws, regulations, and policies that vary depending on the context in which they are used, such as medical, psychiatric, correctional, or law enforcement settings. There is no universal time limit for restraints, but many guidelines emphasize that restraints should only be used as a last resort and for the shortest time possible. In healthcare settings, for example, accreditation organizations like The Joint Commission have standards that require regular assessment, every 15 minutes to 2 hours, to determine if the restraints can be safely removed. Law enforcement protocols for the use of restraints often require that the individual's well-being is monitored continuously, and restraints are removed as soon as it is safe to do so. The specific legal limits and protocols are typically detailed in state statutes, facility policies, or departmental regulations.
