Answer to Question 1

ANS: D
Scopolamine suppresses emesis and motion sickness.
Ipratropium is used to treat asthma and is not indicated for motion sickness.
Atropine does not suppress emesis and motion sickness.
Acetylcholine does not suppress emesis and motion sickness.

Answer to Question 2

ANS: B
A sympathetic agonist would cause pupillary dilation or mydriasis, which is necessary for the ophthalmologist to examine the patient's eyes effectively.
A parasympathomimetic agent would cause miosis or pupillary constriction, which is contraindicated for an eye examination.
A sympathetic antagonist would cause pupillary constriction, which is contraindicated for an eye examination.
A parasympathetic agonist would cause constriction of the pupils, because it mimics the effects of the parasympathetic nervous system; this is contraindicated for an eye examination.
