Which aspect of care at a long-term care facility most clearly suggests that a functional model of care delivery is being used?

A pairing of one registered nurse and one practical nurse provides all the care for a designated pool of residents.

Unlicensed assistive personnel (UAPs) coordinate each resident's care and occasionally delegate to practical nurses.

Registered nurses perform all assessments while UAPs provide all feeding and hygiene.

One nurse is assigned to provide all of a resident's care during a shift.
