Final answer:
A nurse must perform a risk assessment and obtain informed consent before applying a safety reminder device, explaining its purpose and documenting the process.
Step-by-step explanation:
Before applying a safety reminder device, such as restraints in a healthcare setting, a nurse must conduct a comprehensive risk assessment to determine the need for such a device. This involves evaluating the patient's condition to ensure the use of the device is justified. In addition, it is imperative for the nurse to explain the device's purpose and obtain informed consent. Informed consent means the patient is fully aware of the reasons for using the device, potential risks and benefits, and gives their permission freely without coercion. Proper documentation is also an essential part of this process, ensuring that all steps taken are recorded in the patient's medical records.
