A client has a new diagnosis of myasthenia gravis. For which of the following manifestations should the nurse monitor?
Correct Answer: B
Rationale: The correct answer is B: Weakness. Myasthenia gravis is characterized by muscle weakness due to an autoimmune attack on neuromuscular junctions. Monitoring for weakness is essential to assess disease progression and response to treatment. Confusion (A) is not a typical manifestation of myasthenia gravis. Increased intracranial pressure (C) is more commonly associated with conditions like head trauma or brain tumors. Increased urinary output (D) is not directly related to myasthenia gravis and is more indicative of conditions affecting the kidneys or fluid balance.
