Which symptom indicates autonomic dysreflexia (AD)?

The correct answer highlights critical symptoms of autonomic dysreflexia (AD), which often arises in individuals with spinal cord injuries. Goose bumps and nausea are common responses within this condition due to the overactivity of the autonomic nervous system in response to stimuli below the level of injury. This reaction often leads to symptoms like piloerection (goosebumps) and can trigger nausea as the body struggles to regain balance due to heightened sympathetic nervous system activity.

In the context of autonomic dysreflexia, recognizing these symptoms is crucial because they can indicate a medical emergency. If left untreated, AD can result in severe complications, including life-threatening hypertension. Therefore, the presence of goose bumps and nausea serves as a warning sign for caregivers and healthcare professionals to investigate further for potential triggers and intervene appropriately.
