A 49-year-old with myasthenia gravis indicates poor understanding of myasthenic crisis. Which statement indicates poor understanding?

• A. I usually stay in bed most of the time
• B. I should be able to walk around the house unaided
• C. I will monitor my breathing and report increasing weakness
• D. I understand I may need ventilatory support if my weakness worsens

Answer: (A)

In a myasthenic crisis, respiratory muscles can fail as weakness worsens, so recognizing changes in breathing and being prepared for possible ventilatory support are essential. Saying that you usually stay in bed most of the time shows a misunderstanding because it ignores the need to monitor respiratory status and respond quickly to increasing weakness; staying sedentary can worsen deconditioning and delay help, which is risky when the airway muscles may deteriorate. The other statements reflect appropriate understanding: aiming to remain active within tolerance helps preserve strength, and actively monitoring breathing while reporting any increase in weakness shows readiness to seek timely care. Acknowledging that ventilatory support might be needed if weakness worsens aligns with the potential progression of a crisis.
