A 42-year-old female client with a long-standing history of chronic nausea and vomiting but a near-insatiable appetite has had her symptoms attributed to an enzyme deficiency

A)
Cholecystokinin
B)
Ghrelin
C)
Gastrin
D)
Secretin
Ans:
A
Feedback:
Cholecystokinin is responsible for inhibiting food intake as well as stimulating pancreatic enzyme secretion. Ghrelin stimulates food intake, while gastrin stimulates gastric acid production, and secretin inhibits it.
