Chapter 21 : Cholinergic-Blocking Drugs Questions
Question 1 of 5
A 72-year-old man has a new prescription for an anticholinergic drug. He is an active man and enjoys outdoor activities, such as golfing and doing his own yard work. What will the nurse emphasize to him during the teaching session about his drug therapy?
Correct Answer: D
Rationale: Anticholinergic drugs decrease sweating, increasing the risk of heat stroke, especially in elderly patients during outdoor activities. Drowsiness, increased salivation, and diarrhea are not typical effects of anticholinergics.
Question 2 of 5
The nurse will monitor for which adverse effect when administering an anticholinergic drug?
Correct Answer: C
Rationale: Anticholinergic drugs commonly cause dry mouth due to reduced salivary secretions. They also cause urinary retention (not excessive urination), decreased sweating (not diaphoresis), and pupillary dilation (not constriction).
Question 3 of 5
The nurse is reviewing a patient's medication history and notes that the patient is taking the cholinergic blocker tolterodine. Which is an indication for this medication?
Correct Answer: C
Rationale:
Tolterodine is used to treat urge incontinence by reducing bladder detrusor overactivity. It is not indicated for irritable bowel disease, mydriasis, or preoperative secretion reduction.
Question 4 of 5
A patient has been taking tolterodine, but today her prescriber changed her to a newer drug, darifenacin. What advantage does darifenacin have over the tolterodine?
Correct Answer: D
Rationale: Darifenacin has a lower incidence of dry mouth due to its specificity for bladder muscarinic receptors over salivary glands. It is not more effective, does not reduce urinary retention, and is contraindicated in narrow-angle glaucoma.
Question 5 of 5
The nurse working in a preoperative admitting unit administers an anticholinergic medication to a patient before surgery. What is the purpose of this drug in the preoperative setting?
Correct Answer: D
Rationale: Anticholinergic drugs are used preoperatively to reduce oral and gastrointestinal secretions, aiding surgical procedures. They do not primarily decrease pain, relax the patient, or reduce urinary frequency.
