In Guillain-Barré syndrome, what is the most critical nursing action in the acute phase?

• A. Treating infection triggering onset
• B. Strengthening and stretching targeted muscles
• C. Preventing major complications due to immobility
• D. Managing respiratory muscle dysfunction

Answer: (D)

In the acute phase of Guillain-Barré syndrome, the highest risk to life is respiratory failure from weakness of the breathing muscles. The most critical nursing action is to protect and support respiration. This means carefully monitoring respiratory status and readiness to escalate to ventilatory support if needed—watch for rising work of breathing, decreased tidal volume, altered blood gases, and dropping oxygen saturation. Be prepared to assist with airway management, ensure effective airway clearance, and maintain airway patency. Providing measures to keep secretions from pooling and ensuring adequate hydration also support ventilation. While preventing infection triggers, maintaining muscle flexibility, and avoiding immobility complications are important parts of overall care, they do not address the immediate threat to life posed by evolving respiratory failure in this condition.
