A nurse is caring for an adult client in the emergency department who arrives with a sucking chest wound from a gunshot injury. What is the priority nursing action?

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..

Postoperative care for cardiac surgery requires balancing pain management with respiratory function. Knowledge of pulmonary mechanics and the risks of atelectasis is necessary to identify how analgesia facilitates deep breathing and coughing to prevent pneumonia and improve oxygenation.

Choice A rationale

Opioids can cause vasodilation and subsequent hypotension, but reducing blood pressure is not the therapeutic goal of analgesia in this context. While beneficial for cardiac workload, it is not the most critical recovery factor here.

Choice B rationale

Anxiety reduction is a secondary benefit of pain control that improves patient comfort. However, physiological stabilization and the prevention of respiratory complications take precedence over psychological comfort in the immediate postoperative phase after a bypass.

Choice C rationale

Postoperative pain causes guarded, shallow respirations, increasing the risk of lung collapse. Effective analgesia allows the client to perform deep breathing and incentive spirometry, which are vital for maintaining alveolar expansion and preventing secondary infections.

Choice D rationale

Sleep is necessary for cellular repair and overall recovery. While opioids help a patient rest, the primary physiological priority for a bypass patient is maintaining adequate gas exchange through effective ventilation, which requires active respiratory effort.
