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?
Hyperactive bowel sounds
Heart rate 90/min
Blood pressure 90/50 mm Hg
Increased salivation
The Correct Answer is B
A. Hyperactive bowel sounds: Muscarinic agonist poisoning typically results in increased gastrointestinal motility and hyperactive bowel sounds. Atropine, an anticholinergic medication, works by blocking muscarinic receptors and reducing gastrointestinal motility. Therefore, the presence of hyperactive bowel sounds may indicate ongoing muscarinic stimulation and inadequate treatment with atropine.
B. Heart rate 90/min: Atropine is an anticholinergic medication that increases heart rate by blocking the parasympathetic effects of acetylcholine on the heart. Bradycardia is a common manifestation of muscarinic agonist poisoning, and an increase in heart rate following atropine administration indicates reversal of this effect and effective treatment.
C. Blood pressure 90/50 mm Hg: Atropine administration may result in transient hypertension due to its effect on increasing heart rate and cardiac output. Hypotension is a common
manifestation of muscarinic agonist poisoning, and an increase in blood pressure following atropine administration may indicate improvement in cardiovascular function. Therefore, a blood pressure of 90/50 mm Hg may not necessarily indicate effective treatment with atropine.
D. Increased salivation: Muscarinic agonist poisoning typically results in excessive salivation (sialorrhea) due to stimulation of muscarinic receptors in the salivary glands. Atropine administration works by blocking these muscarinic receptors and reducing salivation. Therefore, increased salivation would indicate ongoing muscarinic stimulation and inadequate treatment with atropine.

Correct Answer is A
Explanation
A. To assess compatibility of the verapamil with newly ordered medications: Verapamil is a calcium channel blocker used to treat hypertension, angina, and arrhythmias. It has potential interactions with many other medications due to its effects on cardiac conduction and blood
pressure. Therefore, consulting the pharmacist is important to assess compatibility and potential drug interactions when new medications are prescribed.
B. To request a change in the dosage of the verapamil: Changing the dosage of verapamil may require a healthcare provider's order rather than consultation with a pharmacist.
C. To verify the frequency of administration of the verapamil: The frequency of administration of verapamil is typically determined by the healthcare provider and documented in the prescription. The pharmacist's role may involve dispensing the medication as prescribed but not verifying the frequency unless there are discrepancies.
D. To report the client's refusal to take the verapamil: Reporting the client's refusal to take the medication should be communicated to the healthcare provider for further assessment and
intervention. The pharmacist's role is primarily related to medication dispensing and ensuring appropriate use rather than addressing client refusals.
Correct Answer is ["A","B"]
Explanation
A. Advise the client to change positions slowly: The client's symptoms of dizziness and light- headedness upon standing suggest orthostatic hypotension, which can be managed by advising the client to change positions slowly to minimize blood pressure drops upon standing.
B. Check the client for orthostatic hypotension. Monitor the client for dysrhythmias: The client's symptoms, along with the report of waking up at night to void, are suggestive of orthostatic hypotension, a drop in blood pressure upon standing. Checking for orthostatic hypotension and monitoring for dysrhythmias are appropriate nursing actions to assess and manage this condition.
C. Advise the client to restrict potassium intake: Restricting potassium intake is not indicated based on the client's symptoms of dizziness and light-headedness. This action is not relevant to the situation described.
D. Advise the client to take the medication before bedtime: There is no indication in the scenario provided that medication timing is related to the client's symptoms. This action is not relevant to addressing the client's reported symptoms.
