Final answer:
The nurse is describing Ipratropium, an anticholinergic used alongside beta-2 adrenergic agonists like albuterol to treat bronchospasm in asthma by further opening airways.
Step-by-step explanation:
The drug being described, which is used as an adjunct to a beta-2 adrenergic agonist for the treatment of bronchospasm in asthma, is Ipratropium. Beta-2 adrenergic agonists, such as albuterol, are used to treat acute symptoms of asthma by relaxing the muscles of the airways and opening them wider to make breathing easier. However, Ipratropium is an anticholinergic medication that provides additional bronchodilation by blocking the action of acetylcholine, a neurotransmitter that can cause bronchoconstriction. When used together, these medications can effectively widen the airways and help manage asthma symptoms.
