While providing care for a patient with Guillain-Barre syndrome, the nurse conducts a neurological assessment every four hours. Which finding from the assessment requires immediate intervention by the nurse?
A.
Profuse sweating.
B.
Weakness in the lower legs.
C.
Loss of sensation at T-8.
D.
Leg pain that worsens at night.
The correct answer and Explanation is :
The correct answer is C. Loss of sensation at T-8.
Explanation:
Guillain-Barré syndrome (GBS) is an autoimmune disorder where the body’s immune system mistakenly attacks the peripheral nerves, leading to demyelination. This condition typically starts with weakness and tingling in the lower extremities, which can spread upward to other parts of the body. Neurological assessments in patients with GBS focus on evaluating motor strength, sensory perception, reflexes, and respiratory function, as these areas can be affected during the progression of the disease.
The finding of loss of sensation at T-8 is significant because it indicates the spread of neurological involvement to the thoracic region, suggesting that the disease is ascending. As GBS progresses, the risk of paralysis increases, and if the nerves controlling the diaphragm and respiratory muscles are affected (typically when sensory loss or weakness approaches the thoracic or cervical regions), this can lead to respiratory failure. Immediate intervention is necessary to prevent further complications, such as respiratory arrest. Mechanical ventilation may be required in severe cases where respiratory muscles are weakened or paralyzed.
In contrast:
- Profuse sweating (A) could indicate autonomic dysfunction, which is common in GBS but not immediately life-threatening.
- Weakness in the lower legs (B) is a typical early symptom of GBS but does not indicate a critical complication.
- Leg pain that worsens at night (D) is also common in GBS due to nerve inflammation but does not require immediate intervention unless accompanied by other signs of rapid disease progression.
Loss of sensation at the thoracic level should prompt the nurse to take immediate action due to its potential impact on respiratory function.
