Zorluk: ZorStandard and Transmission-Based Precautions

A practical nurse (PN) is providing care for a client placed on airborne precautions due to active pulmonary tuberculosis. While the PN is emptying the client's urinary drainage bag, the bottom strap of the PN's fit-tested N95 respirator suddenly snaps, causing the mask to pull away from the chin and immediately breaking the protective seal. Which action should the PN take immediately?

  1. Exit the isolation room immediately, perform hand hygiene, and don a new N95 respirator in the hallway or anteroom.Cevap
  2. B
    Press the N95 respirator firmly against the face with a gloved hand to maintain the seal and quickly finish emptying the drainage bag.
  3. C
    Instruct the client to turn their head and cover their mouth while the PN ties the broken strap back together.
  4. D
    Step toward the door, carefully doff the broken respirator into the room's waste receptacle, and call for assistance to get a replacement.

Cevap

The correct answer is to exit the isolation room immediately, perform hand hygiene, and don a new N95 respirator in the hallway or anteroom.
When a respirator seal is compromised in an airborne isolation environment, the nurse's immediate priority is personal safety. The nurse must immediately exit the contaminated room to avoid inhaling airborne pathogens. A new N95 respirator must be donned outside the room before returning to complete any interrupted clinical tasks.

Adım Adım Çözüm

1
Recognize the immediate risk of a PPE breach.
The broken strap eliminates the required negative-pressure seal of the N95 respirator.
An intact, fit-tested seal is mandatory to filter airborne droplet nuclei. Once broken, the nurse is unprotected.
2
Prioritize personal safety over task completion.
The PN immediately halts the clinical task and leaves the contaminated environment.
Continuing client care or manipulating equipment with a compromised respirator directly exposes the nurse to Mycobacterium tuberculosis.
3
Replace the protective equipment following correct protocols.
The PN safely dons a new, intact N95 respirator outside the isolation room.
Airborne precautions dictate that respiratory protection must be donned prior to entering and removed only after exiting the room.
