Final answer:
A nurse can use restraints without a provider's order only in emergencies where there is an immediate threat to safety. The nurse must comply with institutional policies and seek a provider's order as soon as possible after the incident.
Step-by-step explanation:
A nurse may only put a client in restraints without a provider's order in very specific and emergency situations where the immediate physical safety of the patient or others is at risk. For example, if a patient is exhibiting violent behavior and poses an immediate threat to themselves or staff, restraints may be used temporarily until a provider can assess the situation and issue formal orders. It is crucial, however, that the nurse follows the institution's policies and regulations regarding restraints and documents all steps taken during the incident.
Additionally, the use of restraints should be the last resort after all other less restrictive measures have failed or are judged to be ineffective. As soon as the emergency is under control, the nurse should seek a provider's order as required to continue, modify, or discontinue the use of restraints. It's also important to continuously monitor the patient's condition and ensure the least restrictive form of restraint is used to protect the rights and dignity of the patient.
