Final answer:
Functional nursing can be confusing to patients due to the involvement of multiple caregivers, which might cause fragmented care and compromise continuity.
Step-by-step explanation:
One disadvantage of functional nursing is that it might be confusing to patients since multiple health professionals provide care to a single patient. Rather than having one nurse take care of all aspects of a patient's care, in functional nursing, the work is divided among team members according to their specific skills or functions. As a result, patients can become confused because they interact with many different caregivers, which could lead to a sense of fragmentation in care and possibly even compromise the continuity of care that is integral to patient satisfaction and outcomes.
