Question

Quizplus · Accepted Answer

The patient is presenting with signs and symptoms of an asthma exacerbation, including audible wheezing, pursed lips, and low SpO2 levels. The "shark fin" pattern on capnography indicates bronchoconstriction, which can be treated with a beta-agonist such as albuterol to help open up the airways and improve oxygenation. Beta antagonists, alpha agonists, and alpha antagonists do not have a place in the treatment of asthma exacerbations.
