A nurse is teaching a client who has a new prescription for cromolyn. Which of the following information should the nurse include in the teaching?

A. "Cromolyn will assist with dilating the bronchioles in your lungs.": Cromolyn is not a bronchodilator and does not relax airway smooth muscles. Its primary action is to stabilize mast cells and prevent the release of inflammatory mediators. B. "Cromolyn should take effect within 5 minutes.": Cromolyn works as a preventive medication and requires consistent use over time. It does not provide rapid relief of acute bronchospasm or asthma attacks. C. "Cromolyn should be administered 1 hour after exercising.": For exercise-induced asthma, cromolyn should be administered 10–15 minutes before exercising, not after, to prevent symptoms. Timing is important for prophylactic effectiveness. D. "Cromolyn is used to prevent your condition from occurring.": Cromolyn is a mast cell stabilizer used as a preventive therapy to reduce inflammation and prevent asthma attacks. It is most effective when taken regularly or before known triggers.
