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?
Increased salivation
Hyperactive bowel sounds
Heart rate 90/min
Blood pressure 90/50 mm Hg
The Correct Answer is C
A) Increased salivation - Muscarinic agonist poisoning typically presents with
excessive salivation, so increased salivation would indicate ineffective treatment.
B) Hyperactive bowel sounds - Muscarinic agonist poisoning can cause increased
bowel sounds, so this finding would also indicate ineffective treatment.
C) Heart rate 90/min - Atropine is used to counteract the effects of muscarinic
agonists by blocking acetylcholine receptors, leading to an increase in heart rate. A
heart rate of 90/min would indicate that the treatment has been effective.
D) Blood pressure 90/50 mm Hg - Atropine can cause tachycardia and hypertension
as side effects, so a blood pressure of 90/50 mm Hg would not necessarily indicate
effective treatment.
