Zorluk: ZorStandard and Transmission-Based Precautions

An LPN/LVN is preparing to leave the negative-pressure isolation room after bathing a client who has disseminated varicella zoster. The nurse is wearing full transmission-based personal protective equipment, including an N95 respirator, isolation gown, and gloves. Sequence the following actions to demonstrate the safest method for doffing the protective gear.

  1. 1Remove and discard the contaminated gloves inside the isolation room.
  2. 2Unfasten the isolation gown, pull it away from the shoulders, and roll it inside out for disposal.
  3. 3Exit the negative-pressure room and ensure the door is fully closed.
  4. 4Take off the N95 respirator by lifting the bottom strap, then the top strap, without touching the front.
  5. 5Perform thorough hand hygiene using an alcohol-based hand rub or soap and water.

Cevap

The safest doffing sequence is to first remove the gloves, followed by the gown inside the room. Next, exit the room and close the door. Then, remove the N95 respirator outside the room, and finally perform thorough hand hygiene.
The Centers for Disease Control and Prevention (CDC) guidelines require that PPE be removed in a manner that prevents self-contamination. For a client on Airborne and Contact precautions, all contact-related PPE (gloves and gown) must be removed inside the isolation room. The nurse must then exit the room and close the door to maintain the negative-pressure environment before removing the N95 respirator, which protects against airborne particles. Hand hygiene is always performed as the final step.

Adım Adım Çözüm

1
Remove and discard the contaminated gloves inside the isolation room.
The most contaminated PPE is safely disposed of.
Removing gloves first prevents the highly contaminated hands from touching the nurse's body or clean areas of the gown during subsequent doffing steps.
2
Unfasten the isolation gown, pull it away from the shoulders, and roll it inside out for disposal.
The gown is safely removed without contaminating the nurse's uniform.
Contact precautions require the gown to be removed inside the room so that pathogens are not carried into the hallway.
3
Exit the negative-pressure room and ensure the door is fully closed.
The nurse transitions from the contaminated environment to a clean environment.
Airborne pathogens can escape if the door is left open, and the nurse must be in a clean environment before removing respiratory protection.
4
Take off the N95 respirator by lifting the bottom strap, then the top strap, without touching the front.
The respiratory protection is safely removed without self-contamination.
The front of the respirator is heavily contaminated with airborne particles; touching only the straps behind the head prevents transfer of infectious material.
5
Perform thorough hand hygiene using an alcohol-based hand rub or soap and water.
Any remaining pathogens on the nurse's hands are destroyed or washed away.
Hand hygiene is the mandatory final step of any PPE doffing procedure to ensure the nurse does not serve as a vector for infection.
