Final answer:
To prevent transmission in droplet isolation precautions, health workers need to wear a protective coat, face protection, and gloves, following strict hand hygiene and equipment disinfection protocols.
Step-by-step explanation:
In a droplet isolation precautions scenario, it's critical for healthcare workers to wear specified Personal Protective Equipment (PPE) to prevent the transmission of infections through respiratory droplets. Such PPE typically includes a protective coat or gown, face protection such as surgical masks or face shields, and gloves. Furthermore, diligent hand hygiene must be observed before and after patient contact, with hands being washed using detergent and warm water, followed by disinfection. Equipment and surfaces that come into contact with the patient, as seen in Marisa's case, also need to be cleaned thoroughly to prevent contamination. Protocols are in place in various healthcare settings, including the use of Hepa filtration systems in hospitals to maintain a safe environment for both patients and medical personnel. It is also important to note that depending on the risks associated with certain pathogens, additional precautions like respirators or protective suits with their own air supply, as used in BSL-3 or BSL-4 labs, may be necessary.
