Zorluk: OrtaStandard and Transmission-Based Precautions

A registered nurse is preparing to enter the airborne infection isolation room (AIIR) of a client admitted with disseminated varicella-zoster virus. The client requires both airborne and contact precautions. Arrange the following steps for donning personal protective equipment (PPE) in the correct chronological order from first to last.

  1. 1Perform hand hygiene with an alcohol-based hand rub or soap and water.
  2. 2Don an isolation gown, tying all ties at the back of the neck and waist.
  3. 3Place a fit-tested N95 respirator over the nose and mouth.
  4. 4Apply a face shield or goggles.
  5. 5Put on clean gloves, extending them over the cuffs of the gown.

Cevap

The correct sequence for donning PPE is: 1) Perform hand hygiene, 2) Don isolation gown, 3) Place N95 respirator, 4) Apply face shield or goggles, 5) Put on clean gloves.
According to CDC guidelines, the standard sequence for donning PPE begins with hand hygiene to prevent contaminating the clean PPE. Next, the isolation gown is applied to cover the body. The N95 respirator is placed next to ensure a proper seal against the face, followed by eye protection (goggles or face shield). Finally, gloves are donned last so they can securely cover the cuffs of the gown, completing the barrier.

Adım Adım Çözüm

1
Identify the appropriate transmission-based precautions for disseminated varicella-zoster virus.
Determine that Airborne and Contact precautions, plus standard precautions, are required.
Disseminated varicella spreads through both aerosolized airborne particles and direct contact with lesions.
2
Select the first action in the standard CDC PPE donning sequence.
Identify hand hygiene as the starting step.
Hands must be clean before touching clean PPE to prevent transmission of pathogens onto the equipment.
3
Select the first piece of physical PPE to don.
Identify the isolation gown.
The gown covers the torso and arms, providing the largest area of protection, and is secured at the neck and waist before applying facial gear.
4
Determine the correct order for facial protection.
Place the N95 respirator first, followed by the face shield or goggles.
The N95 respirator must be applied directly to the face to ensure an adequate seal; eye protection is then placed over the top.
5
Identify the final step in the sequence.
Put on clean gloves.
Gloves are placed last so they can be pulled up and over the cuffs of the isolation gown, closing any gaps at the wrists.
