In a client with myasthenia gravis, which finding would indicate a myasthenic crisis requiring urgent action?

• A. Respiratory distress.
• B. Severe chest pain.
• C. Headache.
• D. Nausea.

Answer: (A)

Respiratory distress signals a myasthenic crisis because the weakness of the diaphragm and intercostal muscles can collapse the ability to ventilate and exchange gases. When ventilation is severely compromised, airway support is urgently needed to prevent respiratory failure, often with prompt intubation and mechanical ventilation, alongside treatments like plasmapheresis or IVIG to improve neuromuscular transmission. Other symptoms such as chest pain, headache, or nausea do not specifically indicate failing respiratory mechanics from MG and don’t by themselves require immediate airway intervention.
