Question 1 of 5

A nurse is assessing a client who has muscarinic agonist poisoning. Following administration of atropine, which of the following findings should indicate to the nurse that the treatment has been effective?

Correct Answer: C

Rationale: The correct answer is C: Heart rate 90/min. Atropine is a muscarinic antagonist that blocks the effects of excessive acetylcholine, which occurs in muscarinic agonist poisoning. Atropine increases heart rate by blocking the parasympathetic effects on the heart, leading to tachycardia.
Therefore, a heart rate of 90/min post-atropine administration indicates that the treatment has been effective in reversing the bradycardia associated with muscarinic agonist poisoning.
Incorrect Answers:
A: Increased salivation - Atropine decreases salivation.
B: Hyperactive bowel sounds - Atropine decreases bowel motility.
D: Blood pressure 90/50 mm Hg - Atropine can cause hypertension, not hypotension.
