Autonomic Cholinergic Practice Questions
Click on the correct answer.
Current primary therapeutic rationale for using anticholinergic preoperative medication:
- sedation
- antisialagogue effects
- both
- neither
Usual anticholinergic drug doses for preoperative medication does not affect either gastric volume or pH
- true
- false
In using anticholinergic drugs as preoperative medication in a patient with glaucoma: drug least likely to have an effect on pupil size
- scopolamine
- atropine
- glycopyrrolate (Robinul)
Preferred anticholinergic drug when sedation is the principal objective, preoperatively:
- atropine
- glycopyrrolate (Robinul)
- scopolamine
Atropine: most likely to increase heart rate in this patient population:
- young adult
- infants
- elderly
Anticholinergic drug most likely to be used clinically to promote bronchodilation:
- IV atropine
- aerosolized atropine
- aerosolized ipratropium bromide (ipratropium (Atrovent))
- scopolamine
- all of the above
More effective in producing bronchodilation in patients with chronic bronchitis or emphysema:
- albuterol (Ventolin,Proventil) (beta-adrenergic agonist)
- ipratropium (Atrovent) (antimuscarinic agent)
- equally effective
Mydriasis without loss of accommodation
- parasympatholytic
- sympathomimetic
Management of severe bradycardia and A-V block associated with acute myocardial infarction:
- atropine
- neostigmine (Prostigmin)
Atropine is effective in blocking reflex cardiac slowing secondary to:
- carotid sinus stimulation
- pressure on the eyeballs
- peritoneal stimulation which may occur or during surgery
- A & B
- A, B & C
