Final answer:
Bromden, Ruckley, and Scanlon are depicted as chronic patients in 'One Flew Over the Cuckoo's Nest', while Bancini's status as chronic is not explicitly stated.
Step-by-step explanation:
The characters Bromden, Ruckley, Scanlon, and Bancini are from Ken Kesey's novel 'One Flew Over the Cuckoo's Nest.' In the context of chronic patients within the narrative, 'chronic' refers to those who are institutionalized long-term due to severe mental disorders and are not expected to recover. Among the characters listed, Bromden, Ruckley, and Scanlon are depicted as chronic patients in the novel. Bancini, although also a patient in the ward, is not explicitly described with the same chronic status as the others.
