A nurse is reinforcing teaching to a school-age child who has asthma. Which of the following medications should the nurse instruct the child to use to abort an ongoing attack?

The correct answer is D: Albuterol. Albuterol is a short-acting beta-agonist bronchodilator that provides quick relief during an asthma attack by relaxing the muscles in the airways, allowing easier breathing. It is used to abort an ongoing attack and provides rapid relief of symptoms such as wheezing, chest tightness, and shortness of breath. Montelukast (A) is a leukotriene receptor antagonist used for long-term control of asthma symptoms. Fluticasone (B) is an inhaled corticosteroid used for long-term asthma control and prevention of attacks. Cromolyn (C) is a mast cell stabilizer that helps prevent asthma attacks but is not effective for aborting ongoing attacks.
