Difficulty: HardPhysiological Adaptation

A nurse is caring for a client with a complete spinal cord injury at the T3 level. The client suddenly reports a severe, pounding headache. The nurse notes profuse diaphoresis on the client's face and neck, cutis anserina (goosebumps), a blood pressure of 220/115 mm Hg, and a heart rate of 52 bpm. Arrange the following nursing interventions in the priority order they should be performed.

  1. 1Elevate the head of the bed to a high Fowler's position.
  2. 2Loosen any restrictive clothing or tight items, such as abdominal binders.
  3. 3Inspect the indwelling urinary catheter tubing for kinks and palpate the bladder.
  4. 4Apply a topical anesthetic to the rectum and gently assess for a fecal impaction.
  5. 5Administer a prescribed rapid-acting intravenous antihypertensive medication.

Answer

1. Elevate head of bed, 2. Loosen restrictive clothing, 3. Inspect urinary catheter/bladder, 4. Assess for fecal impaction with anesthetic, 5. Administer antihypertensive medication.
Autonomic dysreflexia is a medical emergency characterized by a massive, uncompensated cardiovascular response to stimulation of the sympathetic nervous system. The absolute first priority is to decrease blood pressure immediately using gravity (sitting the client up). Subsequent steps systematically eliminate the most common noxious stimuli from least invasive/most accessible (clothing) to visceral (bladder, then bowel). Medications are a last resort if primary interventions fail.

Step-by-Step Solution

1
Elevate the head of the bed to a high Fowler's position.
Induces orthostatic pooling of blood in the lower extremities.
This immediately reduces venous return and lowers blood pressure, mitigating the immediate threat of hypertensive stroke while other interventions are prepared.
2
Loosen any restrictive clothing or tight items.
Removes external noxious cutaneous stimuli.
Tight clothing, belts, or binders can trigger or exacerbate the sympathetic discharge. This is the fastest trigger to assess and eliminate.
3
Inspect the indwelling urinary catheter tubing for kinks and palpate the bladder.
Identifies or rules out bladder distention.
A distended bladder is the leading cause of autonomic dysreflexia. Draining the bladder often completely resolves the hypertensive crisis.
4
Apply a topical anesthetic to the rectum and gently assess for a fecal impaction.
Identifies or rules out bowel impaction safely.
Bowel impaction is the second most common trigger. The topical anesthetic is mandatory to prevent the digital stimulation from causing a further spike in blood pressure.
5
Administer a prescribed rapid-acting intravenous antihypertensive medication.
Pharmacologically lowers blood pressure.
Medications (e.g., hydralazine, nitrates) are reserved for cases where the trigger cannot be found, cannot be easily removed, or the blood pressure fails to normalize after trigger removal.
