A client with a diagnosis of schizophrenia is experiencing visual hallucinations. The nurse plans care based on the determination that this symptom is related to an alteration in brain function in which lobe of the cerebrum?

Visual hallucinations indicate an alteration in brain function in the cerebrum. The occipital lobe is located in the back of the head and is primarily responsible for seeing and receiving information and is responsible for visual hallucinations. The temporal lobe lies beneath the skull on both sides of the brain and is primarily responsible for hearing and receiving information via the ears. Symptoms indicating an alteration of function in the temporal lobe include auditory hallucinations, sensory aphasia, alterations in memory, and altered emotional responses. The frontal lobe is located in the anterior or front area of the brain and is primarily responsible for motor functions, higher thought processes such as decision making, intellectual insight and judgment, and expression of emotion. Symptoms indicating an alteration of function in the frontal lobe include changes in affect, alteration in language production, alteration in motor function, impulsive behavior, and impaired decision making. The parietal lobe lies beneath the skull at the back and top of the head and is primarily responsible for association and sensory perception. Symptoms indicating an alteration of function in the parietal lobe include alterations in sensory perceptions, difficulty with time concepts and calculating numbers, alteration in personal hygiene, and poor attention span.
