Final answer:
An effective result of salmeterol use for asthma management would be indicated by a daily peak expiratory flow (PEF) measuring 85% above the client's personal best, showing improved airflow. Other findings like pH level or wheezing patterns may be less directly relevant to evaluating the effectiveness of the asthma medication.
Step-by-step explanation:
The student is asking about the effectiveness of the medication salmeterol for treating moderate asthma. An indication of effective asthma management with salmeterol would be demonstrated by improved measures of lung function. In evaluating the effectiveness of the medication, the nurse should look for evidence of improved airflow and reduced respiratory symptoms.
An effective result of using salmeterol would be if the client's daily peak expiratory flow (PEF) measures 85% above personal best (A), as this suggests that the medication is helping to increase the airflow and reduce airway constriction, a common issue in asthma management. This is supported by literature that states the importance of monitoring PEF to evaluate asthma control. In contrast, a pH level of 7.32 (B) may indicate something about the patient's acid-base balance but is less directly related to the effectiveness of salmeterol on airway function. A decreased forced expiratory volume (C) would typically suggest a decline in lung function, not an improvement, and therefore would not indicate effective treatment with salmeterol. Lastly, while having wheezing limited to expiratory phases (D) could be seen in asthma, it does not directly indicate effective control of the asthma with salmeterol.
