Chapter 20 : Cholinergic Drugs Questions
Question 1 of 5
A factory worker has been admitted to the emergency department after an industrial accident involving organophosphate insecticides. The nurse will prepare to administer which drug?
Correct Answer: C
Rationale: Physostigmine, an indirect-acting cholinergic drug, inhibits acetylcholinesterase, reversing neuromuscular blockade from organophosphate poisoning. The other drugs listed are not appropriate antidotes for organophosphate toxicity.
Question 2 of 5
The nurse is providing teaching regarding drug therapy to the husband of a woman with Alzheimer's disease. She was diagnosed 3 months ago, has mild memory loss, and will be receiving donepezil. What is the drug's expected action?
Correct Answer: D
Rationale: Donepezil is used to treat mild-to-moderate dementia in Alzheimer's disease and may improve symptoms like mood and confusion but does not prevent memory loss, reverse the disease, or provide sedation.
Question 3 of 5
A patient has been taking donepezil for 2 weeks as part of the treatment for early stages of Alzheimer's disease. Her daughter calls the prescriber's office and is upset because -Mother has not improved one bit! Which response by the nurse is appropriate?
Correct Answer: C
Rationale: Donepezil may take up to 6 weeks to show improvement in Alzheimer's symptoms. It is not a cure, and dosage changes or administration adjustments should not be made without prescriber approval.
Question 4 of 5
A patient who has been diagnosed with Sj?¶gren's syndrome will be given cevimeline for the treatment of xerostomia. The nurse will monitor for what therapeutic effect?
Correct Answer: B
Rationale: Cevimeline, a direct-acting cholinergic drug, stimulates salivation in patients with xerostomia (dry mouth) associated with Sj?¶gren's syndrome. The other options are incorrect.
Question 5 of 5
The nurse is reviewing the mechanism of action of cholinergic drugs. The desired effects of cholinergic drugs come from the stimulation of which receptors?
Correct Answer: A
Rationale: The desired effects of cholinergic drugs come from muscarinic receptor stimulation. Many undesirable adverse effects are due to nicotinic receptor stimulation. The other options are incorrect.
