Difficulty: HardPhysiological Adaptation

A nurse is caring for a client with a complete T4 spinal cord injury who suddenly reports a severe, pounding headache. The nurse notes facial flushing, profuse diaphoresis above the nipple line, and a blood pressure of 214/118214/118 mm Hg. Arrange the following nursing interventions in the correct order of clinical priority.

  1. 1Elevate the head of the bed to a high Fowler's position.
  2. 2Loosen any restrictive clothing, tight abdominal binders, or anti-embolism stockings.
  3. 3Palpate the bladder for distention and check the indwelling urinary catheter for kinks.
  4. 4Evaluate the rectum for fecal impaction after applying a topical anesthetic ointment.
  5. 5Administer a prescribed rapid-acting intravenous antihypertensive medication.

Answer

The correct sequence of actions for managing autonomic dysreflexia is to first elevate the head of the bed, then loosen restrictive clothing, assess the bladder and catheter, evaluate for bowel impaction, and finally administer an antihypertensive medication.
Autonomic dysreflexia is a medical emergency in clients with spinal cord injuries at or above T6. The uninhibited sympathetic response below the level of injury causes severe vasoconstriction and hypertension. The absolute first priority is to lower the blood pressure immediately by elevating the head of the bed to induce orthostatic pooling. Next, the nurse must systematically identify and remove the noxious stimuli causing the reaction. External stimuli (tight clothing) are addressed first as they are quickest to resolve. Then, internal stimuli are assessed in order of frequency: bladder issues (most common) followed by bowel issues (second most common). Pharmacological interventions are reserved for situations where identifying and resolving the stimulus is ineffective or the blood pressure remains dangerously high.

Step-by-Step Solution

1
Elevate the head of the bed to a high Fowler's position.
Immediate mechanical reduction in systemic blood pressure.
Taking advantage of orthostatic pooling of blood in the lower extremities helps rapidly lower systemic blood pressure to prevent a hypertensive stroke, which is the immediate life threat.
2
Loosen any restrictive clothing, tight abdominal binders, or anti-embolism stockings.
Elimination of potential external noxious stimuli.
External pressure can trigger the exaggerated sympathetic nervous system response. Removing this pressure is rapid and non-invasive.
3
Palpate the bladder for distention and check the indwelling urinary catheter for kinks.
Identification and relief of the primary internal trigger.
A distended bladder is the most common cause of autonomic dysreflexia; emptying the bladder or removing a kink rapidly eliminates the primary stimulus.
4
Evaluate the rectum for fecal impaction after applying a topical anesthetic ointment.
Identification of secondary internal triggers.
Bowel impaction is the second most common cause. A topical anesthetic must be applied prior to the digital rectal exam to prevent further stimulation of the autonomic reflex during the procedure.
5
Administer a prescribed rapid-acting intravenous antihypertensive medication.
Pharmacological control of severe hypertension.
If identifying and removing the physical triggers does not resolve the crisis, or if the triggers cannot be immediately found, medical management is required to lower the blood pressure safely.

Key Concept

Management of autonomic dysreflexia prioritizes immediate blood pressure reduction through physical positioning, followed by the systematic elimination of noxious stimuli, before resorting to pharmacological intervention.
