Certified Pulmonary Function Technologist (CPFT) Practice Exam

In terms of infection control, what is the preferred alternative to nebulization in the PFT lab?

1. Dry powder inhalers

2. Small volume nebulizers

3. Metered dose inhalers

4. Continuous nebulizers

The correct answer is: Metered dose inhalers

The preferred alternative to nebulization in the pulmonary function testing (PFT) lab is the use of metered dose inhalers (MDIs). MDIs deliver medication in a measured dose and can be used without the need for aerosol generation, which helps to reduce the risk of airborne transmission of infectious agents. In contrast to nebulization, which aerosolizes medications, MDIs do not create a mist that can be inhaled by others in the vicinity, thus enhancing safety in terms of infection control. Additionally, MDIs have a quick delivery time and are user-friendly, allowing patients to self-administer medication effectively under the guidance of the healthcare provider. Each dose is precisely pre-measured, promoting accurate dosing and minimizing waste. Proper instruction on the use of MDIs can maximize their effectiveness and ensure that patients receive their medications as intended, contributing to better patient outcomes in the PFT lab setting. Alternative methods like dry powder inhalers also offer benefits in terms of infection control, but metered dose inhalers are often favored in clinical settings for their ease of use and efficiency in delivering medication directly to the lungs without the risk of creating aerosols.
