Question

a nurse is teaching a client about the use of cromolyn to prevent bronchospasm. the nurse should explain that the medication has which of the following therapeutic effects?
increases leukocyte activity
blocks muscarinic receptors
causes bronchodilation
reduces inflammation

Explanation:

Cromolyn is an anti-inflammatory medication used to prevent bronchospasm, typically in asthma. It works by stabilizing mast cells to prevent the release of inflammatory mediators, thereby reducing airway inflammation.

• Increasing leukocyte activity would worsen inflammation, so this is incorrect.
• Blocking muscarinic receptors is the action of anticholinergic medications (like ipratropium), not cromolyn.
• Cromolyn does not directly cause bronchodilation; bronchodilators (like albuterol) perform this action.

Answer:

D. Reduces inflammation
