A nurse is reinforcing discharge teaching with a client who has asthma and a new prescription for salmeterol. Which of the following instructions should the nurse include?

Choice A rationale Salmeterol is classified as a long-acting beta-adrenergic agonist designed to provide sustained bronchodilation over a twelve-hour period. Unlike short-acting agents, it is utilized for maintenance therapy to prevent nocturnal symptoms and improve overall lung function. By binding to beta receptors in the airway smooth muscle, it increases cyclic adenosine monophosphate, leading to relaxation of the bronchioles. This mechanism ensures that the airway remains open, effectively managing chronic symptoms over a long-term duration. Choice B rationale Discontinuing maintenance medications once symptoms appear to resolve is a dangerous practice that often leads to exacerbations. Asthma is a chronic inflammatory condition that requires consistent management even during asymptomatic periods to maintain airway patency. Stopping salmeterol abruptly can result in a return of bronchial hyperresponsiveness and increased frequency of acute attacks. Patients must understand that the absence of symptoms indicates the medication is working effectively, rather than suggesting that the underlying condition is cured. Choice C rationale Salmeterol does not possess primary anti-inflammatory properties, nor does it directly inhibit the production of mucus within the respiratory tract. It is strictly a bronchodilator that acts on the smooth muscle of the airways to cause relaxation. Anti-inflammatory actions are typically achieved through the use of inhaled corticosteroids, which reduce swelling and mucus secretion. Confusing these drug classes can lead to inadequate treatment of the underlying inflammation that characterizes asthma, potentially resulting in long-term lung damage. Choice D rationale Using salmeterol as a rescue medication during an acute asthma attack is contraindicated because its onset of action is too slow to provide immediate relief. Acute bronchospasm requires rapid-acting agents like albuterol to quickly open the airways and restore ventilation. Salmeterol takes significantly longer to initiate its effects, and attempting to use it during an emergency can delay life-saving treatment. Patients must be taught the specific roles of their quick-relief inhalers versus their long-term control medications.
