A client with cholecystitis is receiving propantheline bromide. The client is given this medication because it（）
A. reduces gastric solution production and hypermobility.
B. slows emptying of the stomach and reduces chyme in the duodenum.
C. inhibits contraction of the bile duct and gallbladder.
D. decreases bile secretions.
参考答案：C
解析：
Propantheline bromide is classified as a GI anticholinergic; the medication inhibits muscarinic actions of acetylcholine at postganglionic parasympathetic neuroeffector sites. For gallbladder disease, propantheline has an antispasmodic effect on the bile duct and gallbladder. Although the medication reduces production of gastric solutions and also reduces hypermobility, it isn’t the main reason for the medication. The drug doesn’t slow emptying of the stomach or reduce chyme in the duodenum.
