Which statement indicates successful teaching about inhaler use for a client with asthma?

The statement "Exhale completely before using my inhaler" demonstrates a vital understanding of the proper technique for inhaler use, which is crucial for ensuring that the medication is delivered effectively into the lungs. Proper inhalation technique begins with a full exhalation, as this maximizes the space in the lungs for medication absorption. By completely expelling air from the lungs, the client creates a favorable environment for the incoming medication, ensuring that it can reach the targeted areas of the airways without being obstructed by residual air.

Inhalers require precise usage for optimal effectiveness, and starting with a complete exhalation sets the stage for a successful inhalation. Each of the other options presents important information about inhaler use, but none convey the foundational step of exhaling fully before taking the medication, which is critical for effective treatment of asthma. Understanding this technique emphasizes the importance of preparation in medication delivery, helping clients use their inhalers correctly to manage their asthma symptoms effectively.
