Final answer:
A cough suppressant, such as dextromethorphan, would NOT be appropriate for a patient with chronic asthma as it does not address the underlying inflammation and narrowing of the airways.
Step-by-step explanation:
Of the given options, a cough suppressant, such as dextromethorphan, would NOT be appropriate for a patient with chronic asthma. Asthma is characterized by inflammation and narrowing of the airways, resulting in difficulty in breathing. Cough suppressants work by blocking the cough reflex, but they do not address the underlying inflammation and narrowing of the airways in asthma. Therefore, they are not suitable for managing asthma symptoms.
