Answer to Question 1

B
Feedback:
Actions of loperamide include that it inhibits intestinal peristalsis through direct effects on the longitudinal and circular muscles of the intestinal wall, slowing motility and movement of water and electrolytes. Bismuth subsalicylate inhibits local reflexes. Paregoric works through action on CNS centers that cause GI spasm and slowing. Magnesium citrate is a laxative.

Answer to Question 2

A
Feedback:
Acetylcholine, which communicates between nerves and muscles, is also important as the preganglionic neurotransmitter throughout the autonomic nervous system and as the postganglionic neurotransmitter in the parasympathetic nervous system and in several pathways in the brain. Dopamine is involved in the coordination of impulses and responses, both motor and intellectual. GABA inhibits nerve activity. Serotonin is important in arousal and sleep.
