She has a history of myasthenia gravis, for which she takes oral pyridostigmine. She has had occasional episodes of muscle weakness, blurred vision, and slurred speech recently. Physical examination shows mild ptosis bilaterally. The pupils are normal in size and reactive bilaterally. Muscle strength is 35 at the hips and shoulders. Sensory examination shows no abnormalities. After the administration of 10 mg of edrophonium, her ptosis resolves, and her proximal muscle strength improves to 55. This patient is most likely to benefit from which of the following interventions?? A: Administer timed doses of edrophonium, B: Increase the dose of pyridostigmine, C: Discontinue treatment with pyridostigmine, D: Initiate treatment with intravenous atropine, E: Add glycopyrrolate as needed,  <response>: This is a clinical vignette about a patient with myasthenia gravis who is undergoing preoperative evaluation for elective cholecystectomy surgery. The key findings in the patient are:- History of myasthenia gravis, currently on pyridostigmine- Recent episodes of muscle weakness, blurred vision, slurred speech - Physical exam shows mild bilateral ptosis, normal reactive pupils, proximal muscle weakness - Edrophonium test shows improvement in ptosis and muscle strengthThis indicates the patient has worsening myasthenia gravis symptoms, likely due to inadequate control by her current pyridostigmine dose. The edrophonium test confirms the diagnosis of myasthenia gravis. The question asks what intervention would most benefit this patient preoperatively.B: Increase the dose of pyridostigmine
