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. 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.

A. Oxygen does play a role in maintaining acid-base balance indirectly, as it is required for aerobic metabolism, which produces carbon dioxide that is regulated by the body to maintain acid-base balance. However, this is not its primary role.

B. Oxygen does trigger chemoreceptors, but this is more of a secondary function to regulate breathing based on oxygen and carbon dioxide levels.

C. While oxygen has many roles, its most critical function is providing the necessary support for cellular metabolism, which is vital for energy production in cells.

D. Oxygen is essential for cellular metabolism as it is required for the process of oxidative phosphorylation in mitochondria, which produces ATP, the energy currency of cells.
