A client with COPD has been prescribed acetylcysteine via nebulizer and ipratropium inhaler. The nurse teaches that the ipratropium works by dropdown and the acetylcysteine dropdown

Rationale: • Decreasing mucus production: Ipratropium is an anticholinergic bronchodilator that works by blocking muscarinic receptors in the airways. This leads to relaxation of bronchial smooth muscle and a reduction in airway secretions, which decreases mucus production. This action helps improve airflow and ease breathing in clients with COPD. • thinning and loosening secretions: Acetylcysteine is a mucolytic agent that works by breaking down the disulfide bonds in mucus, making it thinner and less viscous. Thinner mucus is easier to expectorate, which helps decrease coughing and improves airway clearance. It also helps prevent mucus plugging and associated complications in COPD.
