The nurse is preparing to care for a patient who has myasthenia gravis. The nurse will be alert to symptoms affecting which body system in this patient?
Correct answer
C
Rationale
The correct answer is C, respiratory system and facial muscles. Myasthenia gravis is an autoimmune disorder affecting neuromuscular junctions, leading to muscle weakness. Respiratory system involvement can cause respiratory distress. Facial muscle weakness can result in difficulties with swallowing, speaking, and facial expressions. Choice A is incorrect as myasthenia gravis primarily affects voluntary muscles, not memory or cognition. Choice B is incorrect as myasthenia gravis does not typically affect the cardiovascular system. Choice D is incorrect as myasthenia gravis doesn't commonly affect the GI system or lower extremity muscles.
