NUR 2310 Uworld Mental Health NursingA speeding driver sustained a closed-head injury in an acceleration/deceleration accident from striking a tree front end first. Based on the coup-contrecoup phenomenon, which assessments are most likely to be affected related to the involved areas of the brain? Unordered Options Ordered Response 1. Expressive speech, vision 2. Light touch, hearing 3. Sense of position, graphesthesia 4. Weber tuning fork test, cranial nerve I Explanation Coup-contrecoup injury occurs when a body in motion stops suddenly (eg, head hits car windshield), causing contusions (bruising) of brain tissue as the brain moves back and forth within the skull. First, the soft tissue strikes the hard skull in the same direction as the momentum (coup). As the body bounces back, the brain strikes the opposing side of the skull (contrecoup). When the forward collision occurred, the frontal lobe most likely suffered the primary impact (coup). Executive function, memory, speech (Broca area), and voluntary movement are controlled by the frontal lobe. The contrecoup most likely injured the occipital lobe, where vision is processed. (Option 2) The temporal lobe (lateral aspect of the brain) controls hearing and integrates sensory data (eg, auditory, visual, somatic). The Wernicke speech area in the temporal lobe is responsible for language comprehension. Light touch is processed by the sensory cortex in the parietal lobe. (Option 3) An interruption of sensory function indicates injury to either the spinal column or the parietal lobe. These injuries affect proprioception (awareness of body positioning) and graphesthesia (ability to identify writing on the skin, by touch).
