If physical restraints are ordered by the provider, the nurse must perform neurovascular checks on the patient every 15 minutes for the first hour the restraints are applied. The use of physical restraints does not require a court order if the physician can document just cause. However, the order for restraints must be for a limited time frame and cannot be written PRN. Ideally, the restraints should be secured to the bed frame or the chair, not the side rails of the bed.
