What precautions should you take during the draw of blood with someone who has active TB and are in respiratory isolation?

When drawing blood from a patient with active tuberculosis (TB) in respiratory isolation, it's essential to wear appropriate personal protective equipment (PPE), including an N95 respirator or higher-level mask, gloves, gown, and eye protection. Ensure the procedure is performed in a well-ventilated area or within a negative pressure room to minimize airborne transmission risk. Limit the number of staff present during the procedure to reduce exposure and follow strict infection control protocols. After the draw, dispose of materials safely and perform hand hygiene thoroughly.
