A patient is diagnosed with the inability to digest protein and fat. The nurse realizes the enzyme responsible for the digestion of these nutrients is
1. cholecystokinin.
2. secretin.
3. gastric inhibitory peptide.
4. hydrochloric acid.
1
Rationale: Cholecystokinin is secreted in response to the presence of fat, protein, and an acidic pH. The role of CCK is to stimulate secretion of pancreatic digestive enzymes that are necessary for the digestion of fat and protein, to increase contractility of the gallbladder so that bile is released into the duodenum to aid in the absorption of fats, and to inhibit gastric motility in order to slow the digestive process so that absorption can take place. Secretin further stimulates the release of alkaline pancreatic bicarbonate and water which functions to increase the pH of chyme in the duodenum. Gastric inhibitory peptide is a hormone that is secreted in the presence of carbohydrates and fats within the small intestine. It facilitates the digestion of fats and carbohydrates by inhibiting intestinal motility and the secretion of gastric acid and also stimulates insulin secretion. Hydrochloric acid is secreted in the stomach.
