What finding indicates that nebulized albuterol is producing a therapeutic effect for a client with asthma exacerbation?

• A. Constricted pupils
• B. Heart rate of 120/min
• C. Respirations of 24/min
• D. Tremor

Answer: (C)

The best choice indicating a therapeutic effect from nebulized albuterol in a client experiencing an asthma exacerbation is an improvement in respiratory rate, evidenced by respirations of 24/min. In the context of asthma, albuterol, a bronchodilator, works by relaxing the muscles of the airways, thereby easing breathing and increasing airflow to the lungs. A decreasing respiratory rate typically signifies improved ventilation and respiratory function. In asthma exacerbations, elevated respirations (often above normal values, which are typically around 12-20 breaths per minute for adults) reflect distress and inadequate oxygenation. Therefore, a respiratory rate of 24/min indicates there is still some compromise, though it may suggest improvement if the previous rate was significantly higher. Other findings like constricted pupils, a heart rate of 120/min, or tremors may occur due to the sympathomimetic effects of albuterol, but they do not directly indicate the therapeutic effectiveness regarding the improvement in airway function or respiratory condition specific to asthma treatment. While a slight increase in heart rate can be common with bronchodilator use, it does not reflect an improvement in the patient's respiratory status as effectively as observing better respiratory patterns.
