Autonomic dysreflexia is best described as:

Autonomic dysreflexia is best described as:

• A. A mild rash from an allergy.
• B. A common cold.
• C. A severe, but usually not dangerous, condition.
• D. A potentially life-threatening emergency seen with spinal cord injuries.

Answer: (D)

Autonomic dysreflexia is a potentially life-threatening emergency seen with spinal cord injuries. It happens when a noxious stimulus below the level of injury triggers an uncontrolled sympathetic response, causing a rapid and dangerous spike in blood pressure. The body’s normal reflexes to lower that pressure are impaired, so blood pressure can rise enough to threaten the heart, brain, and other organs. Common triggers are a full bladder or kinked catheter, bowel impaction, or tight clothing or devices that press on the body. Because of the high risk of serious complications such as stroke or seizures, this situation requires immediate action: identify and remove the triggering stimulus (for example, check and drain the bladder, relieve bowel impaction, loosen restrictive clothing), have the person sit upright to help lower blood pressure, and obtain urgent medical evaluation if the blood pressure does not rapidly improve. The other options describe benign or unrelated conditions, but this scenario is best described as a sudden, dangerous emergency that demands swift response.
