A nurse is teaching a patient newly diagnosed with asthma about the proper use of a metered-dose inhaler (MDI) with a spacer. Which statement by the patient indicates understanding of the correct technique?
- I should breathe in quickly and deeply as soon as I press the canister
- I will shake the inhaler, attach the spacer, press the canister, then inhale slowly and hold my breath for 10 seconds
- I need to take several quick breaths in and out through the spacer after pressing the canister
- I should press the canister twice quickly to get more medication into my lungs
