A nurse is teaching a client who is obese and has obstructive sleep apnea how to decrease the number of nightly apneic episodes. Which of the following client statements indicates an understanding of the teaching?

Administering a short-acting beta2-agonist (SABA), such as albuterol, is the priority intervention for the nurse to take, as it provides rapid bronchodilation and relieves bronchospasm, which are the main features of status asthmaticus. Status asthmaticus is a severe and life-threatening asthma attack that does not respond to usual treatment and requires immediate medical attention.

a) Determining the cause of the acute exacerbation is important, but not the priority intervention for the nurse to take. The cause may be an allergen, infection, stress, or exercise, but it does not affect the immediate management of status asthmaticus. The nurse should focus on restoring airway patency and oxygenation first, and then identify and avoid triggers later.
b) Obtaining a peak flow reading is important, but not the priority intervention for the nurse to take. The peak flow reading measures the maximum expiratory flow rate and indicates the degree of airway obstruction. However, it may not be feasible or accurate in a child who is experiencing status asthmaticus, as they may be too dyspneic or agitated to perform the test. The nurse should rely on other signs of respiratory distress, such as wheezes, retractions, cyanosis, or pulse oximetry.
c) Administering an inhaled glucocorticoid is important, but not the priority intervention for the nurse to take. Glucocorticoids, such as fluticasone or budesonide, reduce inflammation and mucus production in the airways, but they have a delayed onset of action and are not effective for acute asthma attacks. They are used for long-term control and prevention of asthma symptoms.

These responses are correct and explain how albuterol helps the client's breathing. Albuterol is a short- acting beta2-agonist that causes bronchodilation and relieves bronchospasm, which are the main causes of wheezing and dyspnea in clients who have asthma or COPD. By opening the airways, albuterol improves gas exchange and oxygenation.

b) The medication will decrease coughing episodes. This response is incorrect and does not explain how albuterol helps the client's breathing. Albuterol does not have a direct effect on coughing, which is a reflex response to irritation or obstruction of the airways. Coughing may be beneficial for clearing secretions and mucus from the lungs, but it may also cause bronchoconstriction and inflammation. The nurse should advise the client to use other measures to decrease coughing, such as drinking fluids, using a humidifier, or taking an expectorant.
c) The medication will reduce inflammation. This response is incorrect and does not explain how albuterol helps the client's breathing. Albuterol does not have an anti-inflammatory effect on the airways, which are often inflamed and swollen in clients who have asthma or COPD. Inflammation can contribute to airway obstruction and mucus production, which impair gas exchange and oxygenation. The nurse should inform the client that albuterol is used for quick relief of acute symptoms, but not for long-term control or prevention of inflammation. The client may need to use another medication, such as an inhaled corticosteroid, to reduce inflammation.
e) The medication will stimulate flow of mucus. This response is incorrect and does not explain how albuterol helps the client's breathing. Albuterol does not have a direct effect on mucus production or clearance, which are often increased in clients who have asthma or COPD. Mucus can cause airway obstruction and infection, which impair gas exchange and oxygenation. The nurse should advise the client to use other measures to stimulate flow of mucus, such as drinking fluids, using a humidifier, or taking an expectorant.
