Restraints are devices used to limit a patient's movement and can become medico-legal hazards if not used properly. Restraints should only be used to prevent falls, limit movement, or prevent a patient from hurting others. Common types of restraints include belt restraints, wrist restraints, boxing gloves, and restraining sheets, but they can become hazards if too tight, applied incorrectly, or the wrong size. Nurses must be careful when using restraints to avoid threats to patient safety.
