Final answer:
Steroids are used in asthma treatment to have an anti-inflammatory effect, which helps in reducing airway inflammation and alleviating symptoms.
Step-by-step explanation:
The expected outcome for the use of steroids in clients with asthma is to have an anti-inflammatory effect. Corticosteroids like prednisone are potent anti-inflammatory medications and are considered the most effective treatment for the long-term control of asthma. They work by downregulating the immune system, which in turn reduces the inflammation and edema in the airway, leading to less airway obstruction. This helps to alleviate the symptoms of an asthma attack, such as shortness of breath, wheezing, and tightness of the chest.
