Final answer:
The appropriate PPE for a phlebotomist entering an airborne isolation room is gloves, an N95 respirator, and a gown. This ensures protection against inhalation of airborne particles and prevents skin and clothing exposure to infectious agents.
Step-by-step explanation:
When a phlebotomist enters an airborne isolation room, the appropriate Personal Protective Equipment (PPE) would be gloves, an N95 respirator, and a gown. This choice provides a suitable level of protection when handling patients with infections that require airborne precautions, such as tuberculosis, measles, or varicella. Personnel must ensure that no part of their skin or clothing is exposed, and they should use a full-coverage gown along with gloves and N95 respirator to prevent the inhalation of airborne particles. It is also important to follow rigorous hand hygiene practices and properly dispose of or decontaminate all PPE after use, to avoid any potential spread of the infectious agent.
