Difficulty: HardReduction of Risk Potential

A client with a complete spinal cord injury at the T4T4 level suddenly reports a severe, throbbing headache, blurred vision, and profound nasal congestion. The client's blood pressure is 218/114218/114 mm Hg, and the heart rate is 5252 beats/min. To reduce the immediate risk of a catastrophic cerebrovascular complication, which action must the nurse perform first?

  1. A
    Palpate the client's suprapubic region to assess for acute bladder distension.
  2. B
    Prepare to administer a prescribed rapid-acting intravenous antihypertensive medication.
  3. Elevate the head of the bed to 9090 degrees and lower the client's legs.Answer
  4. D
    Place the client in a supine position with the lower extremities elevated.

Answer

The nurse must first elevate the head of the bed to 90 degrees and lower the client's legs.
The client is exhibiting classic signs of autonomic dysreflexia, a medical emergency in clients with spinal cord injuries at or above the T6T6 level. The massive sympathetic response causes severe hypertension, which poses an immediate risk of stroke or intracranial hemorrhage. The absolute first priority is to utilize gravity to induce orthostatic hypotension and reduce venous return, which rapidly lowers blood pressure. This is achieved by elevating the head of the bed to a sitting position (9090 degrees) and lowering the legs.

Step-by-Step Solution

1
Analyze the clinical manifestations and vital signs.
The severe hypertension, bradycardia, headache, and T4 spinal cord injury indicate autonomic dysreflexia.
Accurate identification of the physiological crisis dictates the emergency protocol.
2
Determine the immediate physiological threat.
The extreme hypertension (218/114218/114 mm Hg) poses a high risk for an acute cerebrovascular accident (stroke).
Prioritization must focus on mitigating the most lethal consequence immediately.
3
Select the fastest intervention to address the primary threat.
Elevating the head of the bed and lowering the legs is the priority action.
This utilizes orthostatic principles to instantly decrease venous return and lower systemic blood pressure before investigating the underlying trigger.

Key Concept

Autonomic dysreflexia management requires immediate positioning to induce orthostatic hypotension before investigating the noxious stimulus.
