Zorluk: ZorStandard and Transmission-Based Precautions

A practical nurse has finished providing care for a client in an airborne infection isolation room who is diagnosed with active pulmonary tuberculosis. The nurse is wearing an isolation gown, clean gloves, a face shield, and a fit-tested N95 respirator. Which sequence correctly describes the appropriate steps for doffing this personal protective equipment (PPE) to minimize the risk of contamination?

  1. A
    Remove the gown, remove the gloves, exit the room, remove the face shield, and finally remove the N95 respirator.
  2. B
    Remove the N95 respirator, remove the face shield, remove the gloves, remove the gown, and then exit the room.
  3. Remove the gloves, remove the face shield, remove the gown, exit the room, and finally remove the N95 respirator.Cevap
  4. D
    Remove the gloves, remove the gown, remove the N95 respirator, exit the room, and finally remove the face shield.

Cevap

The correct sequence is to remove the gloves, then the face shield, then the gown while still inside the room, followed by exiting the room and closing the door before safely removing the N95 respirator.
The correct sequence strictly follows the Centers for Disease Control and Prevention (CDC) guidelines for doffing PPE. The most heavily contaminated item (the gloves) is removed first. The face shield and gown are then safely removed while the nurse is still inside the room. Because the client has active tuberculosis (which requires Airborne Precautions), the N95 respirator must remain securely in place until the nurse has fully exited the room and the door is closed to prevent inhalation of suspended droplet nuclei.

Adım Adım Çözüm

1
Identify the transmission-based precautions required for pulmonary tuberculosis.
The client is on Airborne Precautions, meaning infectious particles remain suspended in the air inside the room.
Understanding the mode of transmission dictates where respiratory protection can be safely removed.
2
Determine the most contaminated pieces of PPE that must be removed first.
Gloves are considered the most heavily contaminated, followed by the front of the face shield and the front of the gown.
PPE must be removed from most contaminated to least contaminated to protect the healthcare worker from self-inoculation.
3
Apply the standard CDC doffing sequence for the body and face.
The gloves are removed first, followed by the face shield (handling only the clean straps behind the head), and then the isolation gown.
This sequence prevents cross-contamination of the nurse's hands, uniform, and mucous membranes.
4
Determine the safest location to remove the N95 respirator.
The nurse must exit the patient's room and ensure the door is closed before grasping the bottom strap, then the top strap, to remove the N95 respirator.
The N95 respirator protects the airway and must remain securely in place until the nurse is completely out of the airborne isolation environment.
