What is the major role of oxygen?

A. Bacteria are not typically detected by a guaiac stool test. Bacterial infections may be diagnosed with a stool culture or other microbiological tests.

B. The guaiac stool test is used to detect hidden (occult) blood in the stool, which can be a sign of gastrointestinal bleeding, such as from ulcers, polyps, or cancer.

C. Steatorrhea refers to the presence of excess fat in the stool, which can be detected by other tests, such as fecal fat analysis, not a guaiac test.

D. Parasites are usually detected through stool microscopy or stool ova and parasite (O&P) tests, not a guaiac test.

A. Pancrelipase is used to replace pancreatic enzymes in clients with pancreatic insufficiency, but it is not typically prescribed in the acute phase of pancreatitis. During acute pancreatitis, the priority is to rest the pancreas, which means withholding pancreatic enzymes.

B. Pantoprazole is a proton pump inhibitor (PPI) that reduces gastric acid secretion. It is commonly prescribed for clients with acute pancreatitis to reduce the risk of stress ulcers, which can occur due to the inflammatory process and the use of medications like corticosteroids.

C. A low-residue diet is not typically indicated in the acute phase of pancreatitis. The client is usually kept NPO (nothing by mouth) initially to rest the pancreas and allow for recovery. Once the acute symptoms subside, a low-fat diet may be introduced.

D. While ambulation is important for overall recovery and preventing complications like deep vein thrombosis, it is not a priority in the acute phase of pancreatitis. Rest and monitoring are more critical at this time.
