A nurse is teaching a client who has a prescription of a nasogastric tube (NG) to treat a pyloric obstruction. Which of the following rationales for the use of the nasogastric tube should the nurse include in the teaching?

A. Steatorrhea:

Steatorrhea refers to the presence of excessive fat in the stool. If a healthcare provider suspects malabsorption or fat digestion issues, they might order a fecal fat test to assess the amount of fat in the stool. This test is different from a guaiac fecal occult blood test (gFOBT), which is designed to detect blood.

B. Parasites:

The detection of parasites in the stool involves specific testing methods, such as microscopic examination of stool samples or specialized tests aimed at identifying the presence of parasitic organisms. A guaiac fecal occult blood test is not designed to detect parasites; its primary purpose is to identify occult (hidden) blood.

C. Blood:

A stool test for guaiac is specifically designed to detect the presence of occult (hidden) blood in the stool. The guaiac test involves placing a small sample of stool onto a test card containing guaiac, and a color change indicates the presence of blood. This test is commonly used to screen for gastrointestinal bleeding.

D. Bacteria:

Detecting bacteria in the stool typically involves stool cultures or specific tests designed to identify bacterial infections or imbalances in the gut microbiota. The guaiac test is not intended for detecting bacteria; its primary focus is on identifying the presence of blood in the stool.

A. Regular insulin:

Regular insulin, also known as short-acting insulin, is commonly used in the initial management of diabetic ketoacidosis. It has a relatively rapid onset of action, making it suitable for addressing the acute and severe nature of DKA.

B. Insulin detemir:

Insulin detemir is a long-acting insulin analog. It is not the preferred choice for addressing the acute insulin needs in DKA; instead, it is used for basal insulin requirements in the maintenance phase of diabetes management.

C. Insulin glargine:

Insulin glargine is a long-acting insulin analog used for basal insulin coverage. Like insulin detemir, it is not the first choice for addressing the acute insulin needs in the initial treatment of DKA.

D. NPH insulin:

NPH (Neutral Protamine Hagedorn) insulin is an intermediate-acting insulin. While it has a role in diabetes management, it is not the preferred choice for the initial treatment of DKA. NPH insulin has a slower onset and longer duration compared to regular insulin.
