A nurse is assigned to care for a client with myasthenia gravis. As the nurse walks into the client’s room, the client complains of abdominal cramps and blurring of vision. Further examination reveals a blood pressure of 80/50 and pupil constriction. The nurse prepares to give which medication?
  1. Methadone (Dolophine)
  2. Naloxone (Narcan)
  3. Atropine sulfate
  4. Acetylcysteine (Mucomyst)
Explanation
Answer: C - Based on the assessment findings, the client is experiencing cholinergic crisis, a condition caused by the overmedication of neostigmine. Overdosage of neostigmine is neutralized by atropine sulfate. Methadone is used in opioid tapering, naloxone is used for the treatment of opioid toxicity, and acetylcysteine is administered to clients with acetaminophen toxicity.
