Which of the following is NOT a correct practice for someone using a metered-dose inhaler (MDI)?

Using a metered-dose inhaler (MDI) correctly is crucial for ensuring effective delivery of medication to the lungs. Shaking the inhaler before use is important because it ensures that the medication is well-mixed and dispensed correctly. Holding the breath for 10 seconds post-inhalation allows the medication more time to settle in the lungs, enhancing its therapeutic effect.

Tilting the head back slightly while inhaling helps to open up the airways, making it easier for the medication to reach deep into the lungs. These practices are consistent with guidelines for the effective use of an MDI.

In contrast, performing puffs in rapid succession is not recommended as it can lead to improper aerosol delivery and reduced effectiveness of the medication. The inhaler needs time to release the medication properly, and taking puffs too quickly can overwhelm the respiratory system, preventing adequate inhalation of each dose. Therefore, this practice does not align with the best practices for using a metered-dose inhaler.
