An agency LPN is a licensed practical nurse who works in temporary healthcare positions. In this career, a staffing agency gives you an assignment based on your experience and the needs of the medical providers with whom they work. Your duties and responsibilities depend on the details of each posting. LPNs provide direct patient care, such as reading vital signs. You assist with patient care and communicate with patients to assess their needs and answer questions. Some agency LPNs work in administrative positions, while others work in a hospital setting, a medical clinic, or an assisted living facility.
