The nurse is administering neostigmine to a client with myasthenia gravis. Which nursing intervention should the nurse implement（）
A. Give the medication on an empty stomach.
B. Warn the client that he’ll experience mouth dryness.
C. Schedule the medication before meals.
D. Administer the medication for complaints of muscle weakness or difficulty swallowing.
参考答案：C
解析：
Because neostigmine’s onset of action is 45 to 75 minutes, it should be administered at least 45 minutes before eating to improve chewing and swallowing. Taking neostigmine with a small amount of food reduces GI adverse effects. Adverse effects of the medication include increased salivation, bradycardia, sweating, nausea, and abdominal cramps. Neostigmine must be given at scheduled times to ensure consistent blood levels.
