Final answer:
A nurse assesses cognitive abilities such as memory, attention, and orientation to distinguish delirium, using the mental status exam to determine any cerebral function impairments, which is essential in emergency settings for determining treatment strategies.
Step-by-step explanation:
A nurse is performing a cognitive assessment to distinguish delirium through evaluating memory, attention, and orientation. Delirium is an acute change in cognition and a disturbance of consciousness, which can be characterized by difficulty sustaining attention, disorganized thinking, and a fluctuating course. This type of assessment is crucial because cognitive impairments can indicate the presence of various conditions affecting cerebral function.
The mental status exam can be crucial in an emergency department setting when a rapid assessment of neurological function is needed. This rapid assessment can be a determinant in proper treatment and the potential for recovery, as it helps to establish the areas of the central nervous system that may be affected by damage or disease. Moreover, during the exam, a neurological exam, including subtests on sensorium and language, can help identify problems with neurological function illustrating the location of cerebrum damage.
