Mrs. Zeno continues to become a weaker despite .treatment with neostigmine. Edrophonium HCL is ordered:

  • A. For its synergestic effect
  • B. Because of the client's resistance to
  • C. To rule out cholinergic crisis Neostigmine
  • D. To confirm the diagnosis of myasthenia
Correct Answer: C

Rationale: The correct answer is C: To rule out cholinergic crisis caused by Neostigmine. Edrophonium HCL is a fast-acting cholinesterase inhibitor used to differentiate between myasthenic crisis and cholinergic crisis. If the patient's weakness improves after administration of edrophonium, it indicates that the weakness was due to myasthenia gravis and not cholinergic crisis caused by excessive neostigmine. Choice A is incorrect because there is no synergestic effect between neostigmine and edrophonium. Choice B is incorrect as resistance to neostigmine is not a valid reason for ordering edrophonium. Choice D is incorrect because edrophonium is used for differential diagnosis, not for confirming the diagnosis of myasthenia gravis.
