Final answer:
Unlicensed assistive personnel and LPNs/LVNs aid registered nurses by performing delegated care tasks.
Step-by-step explanation:
The role of unlicensed assistive personnel (UAP) and LPN/LVNs in hospitals is to aid the RN by performing appropriately delegated care tasks. They work under the direct supervision of a registered nurse and assist with tasks such as taking vital signs, preparing equipment, and providing direct patient care. This allows the RN to focus on more complex tasks and patient needs.
