After reviewing the MRI reports of four patients, which patient would the nurse integrate interventions related to paralysis into the plan of care? - Left cerebral cortex lesion - Cerebral cortex lesion - Lower motor neuron lesion - Right parietal cortex lesion {Ans: Lower motor neuron lesion - The cell bodies of lower motor neurons send axons to innervate the skeletal muscles of the legs, arms, and trunk, and therefore control the body movements. - A lower motor neuron lesion is likely to result in paralysis}Which finding would the nurse expect to identify in the geriatric patient experiencing changes in the reticular activating system (RAS)? - Cerebral tissue atrophy - Decrease in stage IV sleep - Decrease in sensory receptors - Slowed autonomic nervous system (ANS) responses {Ans: Decrease in stage IV sleep RAS is responsible for regulating arousal and sleep-wake transitions}A patient with a lesion in the central nervous system has developed spasticity with hyperreflexia, weakness, paralysis in the lower extremities, and disuse atrophy. Which potential lesion location would the nurse associate with the patient's clinical manifestations? - Reflex arcs - Upper motor neurons - Lower motor neurons - Ventral roots of the spinal nerves. {Ans:
