The correct answer emphasizes the necessity of wearing a personal mask at all times when working with a patient who has measles. Measles is a highly contagious viral infection that can spread through respiratory droplets, which can be released when an infected person coughs, sneezes, or talks. A personal mask serves as a crucial barrier that minimizes the risk of inhaling these infectious droplets.

This precaution is vital due to the airborne nature of measles transmission, as it can linger in the air and contaminate surfaces for an extended period. By requiring a mask at all times, healthcare providers ensure they are protected from potential exposure, which is essential not only for their safety but also for the safety of other patients and staff in the healthcare setting.

While other options include beneficial practices like using gowns and gloves, they do not fully address the primary transmission route of measles, which is airborne. Keeping a close distance to the infected patient without a mask would significantly increase the risk of transmission, thus underscoring the importance of consistent mask use during all interactions with the patient.
