Final answer:
The sending facility is responsible for providing and applying restraints under the mental health standard prior to interfacility transfers to ensure safe and secure transport of the patient.
Step-by-step explanation:
Under the mental health standard, when dealing with interfacility transfers where restraints are requested by the sending facility, it is typically the responsibility of the sending facility to provide and apply the restraints prior to transport. This is to ensure that the individual is securely and safely restrained, adhering to the proper protocols and guidelines for the management of patients who require restraints during transport. The medical staff of the sending facility are often the ones who are trained in the application of such restraints and understand the specific needs and conditions of the patient.
