Final answer:
N95 respirators are required for clients with infections spread via droplet nuclei smaller than 5 microns, such as tuberculosis and measles, to prevent transmission to others.
Step-by-step explanation:
Clients who have infections that can spread via droplet nuclei smaller than 5 microns, such as tuberculosis and measles, require certain protective measures to prevent transmission to others, particularly in healthcare settings. The correct answer to the question is N95 respirators.
N95 respirators are designed to filter out at least 95% of airborne particles, including small droplet nuclei that could contain infectious agents like Mycobacterium tuberculosis or the measles virus. Unlike standard masks, they are capable of filtering particles as small as 0.3 microns. Therefore, they provide a higher level of protection for healthcare workers and others who might be exposed to airborne pathogens.
In addition to N95 respirators, other important measures described in the provided information include the use of negative pressure rooms, which help to contain airborne pathogens and prevent them from spreading throughout healthcare facilities. Also, personal protective equipment (PPE) like gowns, gloves, and face shields contribute to a multi-layered defense strategy against infection.
