12. A phlebotomist is preparing to collect a blood specimen from a patient who has active Mycobacterium tuberculosis Which of the following precautions should the phlebotomist follow
Answer: B
Airborne precautions should be followed.
In the case of a patient with active Mycobacterium tuberculosis, the phlebotomist must adhere to airborne precautions to prevent the spread of the bacteria, which can be transmitted through the air via respiratory droplets.
A) Standard precautions
Standard precautions are the basic level of infection control applicable to all patient care, which includes hand hygiene and the use of personal protective equipment (PPE) to protect against blood and body fluid exposure. However, they do not specifically address the airborne transmission risks associated with tuberculosis, making them insufficient for this scenario.
B) Airborne precautions
Airborne precautions are essential when dealing with patients who have active Mycobacterium tuberculosis, as the bacteria can remain suspended in the air for extended periods. This includes using an N95 respirator or a higher-level mask, ensuring proper ventilation, and placing the patient in a negative pressure room, all of which are critical to preventing transmission.
C) Contact precautions
Contact precautions are designed to prevent the spread of infections that are transmitted through direct contact with the patient or contaminated surfaces. While important for certain infections, they do not address the airborne nature of tuberculosis and would not be adequate in this case.
D) Droplet precautions
Droplet precautions are utilized for infections that are transmitted through large respiratory droplets, such as influenza. However, tuberculosis requires airborne precautions due to its ability to be transmitted via tiny droplets that can linger in the air, thus making droplet precautions inadequate for this situation.
Conclusion
Airborne precautions are the most appropriate and necessary measures for phlebotomists handling patients with active Mycobacterium tuberculosis, as they directly address the transmission risks associated with this airborne pathogen. Other options, such as standard, contact, and droplet precautions, do not provide the necessary protection against the airborne transmission of tuberculosis, highlighting the importance of adhering to the correct guidelines in healthcare settings.
