Final answer:
The client needs additional instruction about the appropriate use of corticosteroid inhalers for long-term control and bronchodilator inhalers for acute relief of asthma symptoms.
Step-by-step explanation:
Based on the given information, additional instruction is needed when the client makes the statement: "I use my corticosteroid inhaler each time I feel short of breath."
This statement indicates that the client is using the corticosteroid inhaler as a short-term, fast-acting drug for an asthma attack, which is incorrect. Corticosteroid inhalers are typically used for long-term control of asthma, to prevent asthma attacks from occurring. Short-term, fast-acting relief during an asthma attack is provided by bronchodilator inhalers.
Therefore, the client needs to be educated about the appropriate use of corticosteroid inhalers for long-term control and bronchodilator inhalers for acute relief of asthma symptoms.
