Chapter 20 : Cholinergic Drugs Questions
Question 1 of 5
A patient who has had abdominal surgery has been discharged on a cholinergic drug to assist in increasing gastrointestinal peristalsis. The nurse will teach this patient to look for which therapeutic effect?
Correct Answer: C
Rationale: In patients with decreased GI peristalsis postoperatively, a cholinergic drug should result in increased bowel sounds, passage of flatus, and bowel movements, indicating enhanced GI peristalsis. The other options are not the primary therapeutic effects.
Question 2 of 5
A cholinergic drug is prescribed for a patient with a new diagnosis of myasthenia gravis, and the nurse provides instructions to the patient about the medication. What is important to include in the teaching?
Correct Answer: C
Rationale: Taking the medication 30 minutes before meals allows time for the onset of action and therapeutic effects during the meal, improving swallowing and chewing in myasthenia gravis. Doses should be spaced evenly, and taking with meals may not prevent GI distress. Taking only when difficulty swallowing occurs is incorrect.
Question 3 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 4 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 5 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.
