Upon auscultation of a client's lung sounds, the nurse notices a high-pitched wheezing sound. What condition is the likely cause of this sound?

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. Anti-inflammatory drugs do not primarily work by increasing blood flow to the tissues. While some may have vasodilatory effects, their primary function is to reduce inflammation.

B. Anti-inflammatory drugs do not directly decrease scar formation. They reduce inflammation, which may indirectly help prevent excessive scarring in tissues affected by chronic inflammation, but this is not their primary action.

C. The main action of anti-inflammatory drugs, such as nonsteroidal anti-inflammatory drugs (NSAIDs) or corticosteroids, is to block the chemical mediators of inflammation, such as prostaglandins. This reduces pain, swelling, and other symptoms of inflammation.

D. Anti-inflammatory drugs do not directly enhance the body's immune system. In fact, some, like corticosteroids, may suppress immune responses to reduce inflammation.
