A client with a cold is taking an antitussive medication. Which assessment information indicates to the nurse that the medication is effective?

A. Expectorating bronchial secretions: This outcome is more closely associated with expectorants, which loosen mucus in the airways. Antitussives, by contrast, suppress the cough reflex and are not intended to increase mucus clearance or productive coughing.B. Reports reduced nasal discharge: Reduced nasal discharge is typically an effect of decongestants or antihistamines, not antitussive medications. Antitussives target the cough reflex, not nasal secretions.C. Able to sleep through the night: While improved sleep may result from reduced coughing, it is a secondary and nonspecific outcome. The ability to sleep could be influenced by other factors such as overall symptom relief, not necessarily the effectiveness of the antitussive alone.D. Denies having coughing spells: Antitussives are designed to suppress the cough reflex, particularly in cases of dry, nonproductive cough. A report of no more coughing spells directly reflects the intended therapeutic effect of the medication.
