Difficulty: MediumPhysiological Adaptation

A nurse is caring for a client with a T4 spinal cord injury who suddenly develops a severe, throbbing headache, profuse diaphoresis above the level of the injury, and a blood pressure of 220/115 mm Hg. Arrange the following nursing interventions in the priority order of execution.

  1. 1Place the client in a high Fowler's position.
  2. 2Examine the urinary catheter system for kinks or obstruction.
  3. 3Assess the rectum for the presence of fecal impaction.
  4. 4Administer a prescribed rapid-acting antihypertensive medication.

Answer

The correct sequence of actions for autonomic dysreflexia is: 1. Place the client in a high Fowler's position, 2. Examine the urinary catheter system for kinks or obstruction, 3. Assess the rectum for the presence of fecal impaction, and 4. Administer a prescribed rapid-acting antihypertensive medication.
The utmost priority in autonomic dysreflexia is to immediately lower blood pressure to prevent severe complications, such as a hemorrhagic stroke. Elevating the head of the bed accomplishes this rapidly through orthostatic changes. The subsequent steps focus on locating and eliminating the noxious stimulus triggering the sympathetic response, checking the most common causes first: the bladder, then the bowel. If these nursing measures fail to resolve the crisis, rapid-acting antihypertensives are administered.

Step-by-Step Solution

1
Recognize the clinical presentation of autonomic dysreflexia.
The client is identified as experiencing a life-threatening hypertensive emergency due to an exaggerated sympathetic response.
The combination of a T4 spinal cord injury, extreme hypertension, diaphoresis, and a severe headache strongly indicates autonomic dysreflexia.
2
Determine the most immediate physical intervention to mitigate stroke risk.
Identify that elevating the head of the bed (high Fowler's) takes precedence over all other actions.
This position leverages gravity to pool blood in the lower extremities, thereby reducing venous return and acutely lowering blood pressure.
3
Identify the logical sequence for assessing and removing potential noxious stimuli.
Prioritize checking the bladder first, followed by the bowel.
Bladder issues (such as a kinked catheter) are the most frequent cause and the quickest to resolve, making it the next logical step before assessing the bowel.
4
Determine when pharmacological intervention is indicated.
Place medication administration as the final step in the sequence.
Antihypertensives are utilized if the underlying cause cannot be found or if blood pressure remains dangerously high after attempting to remove the stimulus.
