Step-by-step explanation:
The unique function of the nurse is to assist the individual, sick or well, in the performance of those activities contributing to health or its recovery (or to peaceful death) that the person would perform unaided if they had the necessary strength, will, or knowledge.
For example, a nurse may help a patient in getting out of bed and walking around after surgery to prevent complications and promote healing.
