Private duty registered nurses (RNs) provide patient care in the client's home or an assisted living facility. As a private duty RN, you check patient vital signs at regular intervals, administer medication, perform necessary tests with medical equipment, change wound bandages, and oversee nursing assistants who are also working with the patient. You may also need to insert catheters, IV lines and infusions, administer oxygen, and utilize other medical treatment with machines when required. Keeping accurate documentation is also vital to ensure any changes in the patient's health is communicated to the patient's physician. These kinds of changes may require the plan of care to be updated.
