Final answer:
A nurse must evaluate a patient for myasthenia gravis before administering anticholinergic drugs. Pilocarpine, a muscarinic agonist, is the antidote for atropine poisoning, while anxiolytics are used for their anti-anxiety properties.
Step-by-step explanation:
Before administering belladonna alkaloids, which are anticholinergic agents, it is most important for the nurse to assess the patient for a history of myasthenia gravis. This is because anticholinergic drugs can exacerbate muscle weakness in patients with myasthenia gravis, potentially leading to a myasthenic crisis. In the context of atropine poisoning, the correct antidote is a muscarinic agonist, specifically pilocarpine, as it can help counteract the muscarinic receptor blockade caused by atropine.
As for the type of drug that would have anti-anxiety effects, medications known as anxiolytics are commonly used. Examples of anxiolytics include benzodiazepines and certain selective serotonin reuptake inhibitors (SSRIs). It is important to use such medications with caution, as they can have side effects and the potential for dependency.
The nurse must assess for myasthenia gravis before administering anticholinergic drugs such as belladonna alkaloids. The antidote for atropine poisoning is a muscarinic agonist, specifically pilocarpine, and anxiolytics are drugs that would typically have anti-anxiety effects.
