A nurse is teaching a client about taking an expectorant to treat a cough. The nurse should explain that this type of medication has which of the following actions?

A. Suppresses the urge to cough – This describes the action of antitussives, not expectorants. Antitussives are used to relieve dry, nonproductive coughs by suppressing the cough reflex. B. Stimulates secretions – This is the correct action of expectorants. They thin and loosen mucus in the airways, making it easier to cough up and clear from the respiratory tract. C. Reduces inflammation – This is typically the action of anti-inflammatory medications, such as corticosteroids, not expectorants. D. Dries mucous membranes – This effect is seen with anticholinergic or antihistamine medications, which are not expectorants.
