Final answer:
An LPN may be able to perform hemodialysis under the direct supervision of a registered nurse, assisting in various tasks related to patient treatment and monitoring.
Step-by-step explanation:
The ability of a licensed practical nurse (LPN) to perform hemodialysis can vary depending on the region and the specific regulations in place. However, under the direct supervision of a registered nurse (RN), an LPN may assist and focus on providing dialysis treatments. In this role, an LPN may take part in activities such as reviewing patient history, monitoring the dialysis process, taking and reporting a patient's vital signs, and preparing solutions and equipment to ensure the procedures are accurate and sterile.
