A teenage patient was recently in a motorcycle accident and suffered a closed head injury. Although the patient's family said the patient has always been even-tempered and reasonable, now the patient is frequently angry and is demonstrating poor impulse
control. Which area of the patient's brain does the nurse suspect may have been injured in the accident?
1. Temporal lobe
2. Frontal lobe
3. Occipital lobe
4. Parietal lobe
Answer: 2
Explanation: Problems in the temporal lobe can lead to visual or auditory hallucinations, aphasia, and amnesia. When normal frontal lobe functioning is altered, destabilization of emotions, a loss of impulse control, and personality changes occur. Problems associated with the occipital region include visual field deficits, blindness, and visual hallucinations. The inability to recognize objects by touch or recognize parts of one's own body, and problems calculating, writing, and drawing suggest problems in the parietal lobe.
