The duties of a travel nurse practitioner (NP) focus on providing health care to patients in different locations. A travel nurse practitioner still works in a clinical setting such as a hospital or healthcare clinic where they provide primary patient care, often as a locum tenens nurse. This term means that you work when full-time staff is unavailable or when a facility is understaffed. As an NP, your responsibilities focus on examining patients, making a diagnosis, and providing treatment when necessary. In some areas, a nurse practitioner is required to work under the supervision of a physician.
