A client with full-thickness and circumferential burns to the chest has been intubated and is experiencing pressure from edema that is inhibiting chest wall expansion.
Which procedure should the nurse anticipate for this client?

Evaluating neurological progression in traumatic brain injury involves applying the Glasgow Coma Scale and understanding brainstem function. Recognising the shift between abnormal posturing patterns is critical for identifying descending levels of brain injury and worsening central nervous system herniation.

Choice A rationale

Improved motor response, such as moving from abnormal posturing to localizing pain or following commands, indicates neurological recovery. This reflects better integration of the motor cortex and brainstem, suggesting that the initial injury or pressure is resolving.

Choice B rationale

Decorticate posturing involves damage to the corticospinal tract, while decerebrate posturing indicates more severe damage lower in the midbrain or brainstem. Progressing from decorticate to decerebrate signals significant neurological deterioration and potential brainstem herniation.

Choice C rationale

Decreased agitation can sometimes be a positive sign of recovery or a neutral sign of sedation. It does not specifically indicate worsening neurological status unless accompanied by a significant drop in the overall level of consciousness.

Choice D rationale

Increased responsiveness to external stimuli is a hallmark of neurological improvement. It suggests that the ascending reticular activating system and cerebral cortex are becoming more functional and integrated, which is the opposite of a worsening clinical state.

Neurological assessment using motor responses helps determine the level of brainstem involvement. This scenario requires applying knowledge of the Glasgow Coma Scale and motor pathways to distinguish between pathological posturing and more integrated, purposeful motor functions.

Choice A rationale

Purposeful movement indicates that the motor cortex or higher brain centers are successfully processing stimuli. Moving away from pain represents a significant improvement from decorticate posturing, which involves damage to the corticospinal tract and midbrain.

Choice B rationale

Decerebrate posturing involves rigid extension of the arms and legs, signifying deeper brainstem injury or herniation. This change indicates neurological deterioration rather than improvement, as it suggests the lesion has progressed lower into the pons.

Choice C rationale

Pupils that are fixed and dilated at 6 mm indicate loss of autonomic function and severe cranial nerve III compression. This is a sign of increasing intracranial pressure and brainstem failure, representing a critical clinical decline.

Choice D rationale

Flaccid paralysis is often the most severe motor finding, indicating a loss of all muscle tone and spinal reflex arcs. In the context of traumatic brain injury, this usually signals profound neurological collapse rather than recovery..
