While caring for a client with a cervical spine injury, which assessment finding should the nurse report to the healthcare provider immediately?

Rationale: A. Sluggish pupillary response: A delayed pupillary reaction may indicate increased intracranial pressure or neural pathway involvement but is not immediately life-threatening. It warrants monitoring and documentation rather than urgent intervention unless accompanied by other neurological changes. B. Respiratory rate 6 breaths/minute: A severely decreased respiratory rate signals respiratory compromise from loss of diaphragmatic or intercostal muscle control, common with high cervical spine injuries. This finding indicates impending respiratory arrest and requires immediate airway and ventilatory support. C. Average urinary output 20 mL/hour: Reduced urine output suggests decreased renal perfusion or possible neurogenic bladder, but it is not immediately life-threatening. It should be reported for evaluation but is secondary to managing respiratory failure risk. D. Heart rate 140 beats/minute: Tachycardia may occur due to pain, anxiety, or autonomic disruption but does not pose the same acute risk as respiratory depression. It should be monitored and managed appropriately after ensuring adequate oxygenation and ventilation.
