Medical Pharmacology Practice Questions: Cholinergic Drugs

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