A patient with a history of asthma enters the Emergency department with severe dyspnea, accessory muscle involvement, neck vein distention, and severe inspiratory/expiratory wheezing. The nurse should prepare to assist the physician with which procedure if the patient does not respond to initial interventions?

A. Laxatives are used to relieve constipation by promoting bowel movements, not for treating diarrhea.

B. Antimotility agents work by slowing down the movement of the intestines, which can reduce diarrhea, but they do not specifically absorb excess fluid in the fecal matter.

C. Adsorbents, such as activated charcoal or kaolin-pectin, work by absorbing excess fluid in the fecal matter in the colon, which helps to reduce diarrhea without affecting transport processes across the intestinal membranes.

D. Bulk-forming agents, like psyllium, absorb water and increase the bulk of stool, which is used for constipation rather than diarrhea.

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.
