Case Study-Asthma (Peds) Exhibits Which diagnostic test does the nurse expect to be ordered to determine the status of the client?

A. Electrolyte levels: While important in general health assessment, electrolytes are not specific to evaluating asthma severity or lung function. They would not determine the respiratory status directly. B. Pulmonary function test including peak flow: This is the most relevant diagnostic tool for asthma. It measures airflow limitation and helps assess the severity of the asthma exacerbation and response to treatment, guiding both immediate care and long-term management. C. CBC: A CBC may show signs of infection or inflammation but does not assess lung function. It is not specific enough to determine the status of an asthma exacerbation or guide bronchodilator therapy. D. Allergy skin testing: This may be done later to identify triggers in chronic asthma management, but it is not useful for acute status assessment or immediate treatment decisions.
