How should a nurse monitor for progression of spinal cord injury after initial stabilization?

• A. Serial motor and sensory exams, monitor autonomic function (bladder/bowel), reflex changes, and imaging if status changes.
• B. Daily blood pressure only.
• C. Nutritional intake alone.
• D. Imaging only when pain increases.

Answer: (A)

Ongoing neuro and autonomic assessment is essential to detect progression after spinal cord injury. After initial stabilization, the injury can evolve from edema, secondary hemorrhage, or new compression, so regular checks help catch changes early. Serial motor and sensory exams track shifts in strength and sensation compared with the baseline, documenting any new or worsening deficits in key muscle groups and dermatomes. Monitoring autonomic function—bladder and bowel control, as well as cardiovascular status like blood pressure and heart rate—reveals changes in autonomic control and helps identify issues such as neurogenic shock or impending autonomic dysreflexia. Reflex changes also provide important timing information: spinal shock can mask reflexes early on, and the return of reflex activity or the development of hyperreflexia and changes in tone indicate progression toward the longer-term phase of injury. Imaging is used when the clinical status changes or there is concern for ongoing compression or instability; CT assesses bone injury, while MRI can reveal cord edema, contusion, or compressive lesions and guide decisions about decompression or surgical stabilization. This integrated monitoring approach enables timely intervention to limit secondary injury and optimize outcomes.
