Which finding indicates a client may have delirium according to their recent behavior change?

A change in the level of consciousness is a critical indicator of delirium. Delirium is characterized by an acute confusion state that can include fluctuations in awareness and responsiveness to the environment. This condition often presents with alterations in cognition, attention, and perception, which may manifest as either increased or decreased awareness and responsiveness.

Individuals with delirium typically exhibit variability in their consciousness, often described as being drowsy, lethargic, or overly alert and agitated at different times. This fluctuation stands in contrast to stable states observed in other conditions, such as dementia, where the level of consciousness remains generally intact.

In a mental health assessment context, noticing a change in the client's level of consciousness invites further evaluation and intervention, as it may indicate an underlying medical condition or the need for immediate care.
