When providing care to a client under airborne isolation, which procedure is crucial?

1. Wearing a surgical mask only when leaving the room

2. Washing hands after all procedures

3. Limiting interactions with other clients

4. Having the client wear a mask at all times

The correct answer is: Washing hands after all procedures

Washing hands after all procedures is crucial when providing care to a client under airborne isolation because it is one of the most effective methods for preventing the spread of infection. Hand hygiene is fundamental in healthcare settings, especially when dealing with pathogens that can be transmitted through the air. Proper handwashing removes microorganisms from the caregiver’s hands, which protects both the healthcare provider and other patients from potential exposure to infectious agents. In airborne isolation, the pathogens of concern are often highly transmissible and can remain suspended in the air for extended periods. Therefore, ensuring that hands are clean before and after any contact with the patient or the environment reduces the risk of carrying infectious particles to other surfaces or individuals. The other options provided do not encompass the comprehensive infection control practices required in airborne isolation. While wearing a surgical mask is important, it alone does not mitigate the full risk of spreading infection if hand hygiene is neglected. Limiting interactions with other clients is also important but is part of a broader approach to patient safety and not a standalone measure. Similarly, having the client wear a mask can reduce transmission risk but does not replace the need for effective hand hygiene. Therefore, the emphasis on handwashing reflects its critical role in infection control procedures within airborne isolation contexts.
