ATI Advanced Pharmacology Final Exam I | Nurselytic

Correct Answer: C

Rationale: The correct answer is C: Respiratory and facial muscles. Myasthenia gravis is an autoimmune disorder that affects the neuromuscular junction, leading to muscle weakness and fatigue. Symptoms commonly affect muscles involved in breathing (respiratory) and facial expressions, such as difficulty swallowing, breathing, speaking, and facial drooping. Monitoring these systems is crucial as respiratory muscle weakness can lead to respiratory failure.
Choice A is incorrect because myasthenia gravis does not typically affect gastrointestinal or lower extremity muscles primarily.
Choice B is incorrect as the primary symptoms of myasthenia gravis do not involve the central nervous system but rather the neuromuscular junction.
Choice D is incorrect as myasthenia gravis does not directly impact the cardiovascular system or postural muscles.
