A nurse is educating a patient about the use of antitussive medications. Which statement by the patient indicates a need for further teaching?

A. "I should avoid antitussives if I have a productive cough with mucus.": Antitussives can inhibit the body’s ability to clear mucus when coughing is suppressed. In the case of a productive cough, clearing secretions is essential to prevent airway obstruction and secondary infections. B. "Antitussives are helpful in clearing mucus from my lungs during a productive cough.": Antitussives reduce the cough reflex and do not aid in mucus clearance. Their use during a productive cough can lead to mucus retention, worsening congestion and increasing the risk of complications such as pneumonia. C. "Using antitussives for a productive cough can lead to mucus buildup in my airways.": Suppressing a productive cough prevents the expulsion of mucus, which can accumulate in the lungs. This can impair gas exchange and create an environment for bacterial growth. D. "Antitussives are used to suppress a dry, nonproductive cough.": These medications are most appropriate when there is no mucus to expel. They help reduce the frequency and intensity of dry coughing, especially when it interferes with sleep or comfort.
