The nurse is performing a mental status examination on a male client diagnosed with a subdural hematoma. This test assesses which of the following?
A. Cerebellar function
B. Intellectual function
C. Cerebral function
D. Sensory function
Correct Answer: C. Cerebral function
The mental status examination assesses functions governed by the cerebrum. Some of these are orientation, attention span, judgment, and abstract reasoning. Cerebrum is the largest part of the brain and is composed of right and left hemispheres. It performs higher functions like interpreting touch, vision, and hearing, as well as speech, reasoning, emotions, learning, and fine control of movement.
Option A: Cerebellar function testing assesses coordination, equilibrium, and fine motor movement. Cerebellum is located under the cerebrum. Its function is to coordinate muscle movements, maintain posture, and balance.
Option B: Intellectual functioning isn’t the only cerebral activity. When assessing intelligence to make decisions about individuals, attention has been paid almost exclusively to general intelligence, as reflected in a composite intelligence quotient, or IQ. That is, a single number, embodied in the IQ, is used to portray an individual’s mental ability.
Option D: Sensory function testing involves assessment of pain, light-touch sensation, and temperature discrimination. Assessment of sensory function helps to identify the different pathways for light touch, proprioception, vibration, and pain. Use a pinprick to evaluate pain sensation.
