Which signs and symptoms would a nurse practitioner expect in a patient with delirium?

In a patient with delirium, all of the listed signs and symptoms are commonly observed and associated with this acute confusional state. Delirium is characterized by a rapid onset of confusion and fluctuating level of consciousness.

A disruptive sleep/wake cycle is often seen in patients with delirium as they may experience difficulties in maintaining a regular sleep pattern. This can lead to further cognitive disturbances and exacerbate the confusion.

An altered level of consciousness (ALC) is a hallmark feature of delirium. Patients may exhibit a range from hyperalertness to drowsiness, which can change frequently. This fluctuating state is key in the diagnosis of delirium.

Poor concentration is also typical in those experiencing delirium. Patients may have difficulty focusing on tasks or conversations, which is reflective of the overall cognitive impairment associated with the condition.

Since all three signs and symptoms are common manifestations of delirium, it is clear why the comprehensive choice is the most appropriate answer.
