Question 1 of 5
Which of the following findings should indicate to the nurse that a client with myasthenia gravis taking neostigmine is experiencing an adverse effect?
Correct Answer: D
Rationale: The correct answer is D: Miosis. Neostigmine is a cholinesterase inhibitor used to treat myasthenia gravis. Miosis, or excessive constriction of the pupil, is a sign of cholinergic crisis which can occur due to neostigmine overdose. This adverse effect indicates excessive stimulation of the parasympathetic nervous system, leading to symptoms such as increased salivation, bronchoconstriction, and miosis. Tachycardia (
A) is not typically associated with neostigmine use, oliguria (
B) is not a common adverse effect, and xerostomia (
C) is the opposite of the expected effect of increased salivation due to cholinergic stimulation.
