A) Green, stringy emesis
B) Bright red, bloody emesis
C) Thick, brownish, foul-smelling emesis
D) Clear mucous-looking emesis
Ans: C
Feedback:
The pylorus is located between the body of the stomach and the duodenum. At the end of the pyloric canal, the circular smooth muscle layer thickens to form the pyloric sphincter. This muscle serves as a valve that controls the rate of stomach emptying and prevents the regurgitation of intestinal contents back into the stomach. Therefore, if the pyloric sphincter is incompetent, intestinal content will flow back into the stomach.
