Zorluk: ZorStandard and Transmission-Based Precautions

A practical nurse is gathering supplies to assist a healthcare provider with an aerosol-generating procedure for a client diagnosed with a severe acute respiratory pathogen. The nurse must apply full personal protective equipment (PPE) prior to entering the negative-pressure isolation room. Arrange the following steps for donning the required PPE in the correct chronological order.

  1. 1Perform hand hygiene using an alcohol-based hand rub or antimicrobial soap and water.
  2. 2Put on the fluid-resistant isolation gown and secure the ties at the neck and waist.
  3. 3Don the N95 respirator, securing the elastic headbands, and perform a seal check.
  4. 4Place the face shield over the eyes and face, adjusting the headband to fit securely.
  5. 5Put on clean gloves and pull the edges carefully over the wrists of the isolation gown.

Cevap

The correct sequence for donning PPE is: 1) Perform hand hygiene, 2) Put on the isolation gown, 3) Don the N95 respirator, 4) Place the face shield, and 5) Put on clean gloves.
Following the standardized Centers for Disease Control and Prevention (CDC) sequence for donning PPE ensures maximum protection and prevents gaps in the barrier. Hand hygiene always occurs first to prevent contaminating clean supplies. The gown provides foundational body coverage and is applied next. The N95 respirator must then be applied to ensure a proper, unobstructed seal directly against the face. This is followed by the face shield, which sits externally to protect the mask and eyes from splashes. Finally, gloves are applied last so they can be securely pulled over the gown cuffs, eliminating exposed skin at the wrists.

Adım Adım Çözüm

1
Perform hand hygiene using an alcohol-based hand rub or antimicrobial soap and water.
Hands are decontaminated prior to handling clean PPE.
This reduces the risk of transferring transient flora to the protective equipment before it is worn.
2
Put on the fluid-resistant isolation gown and secure the ties at the neck and waist.
The torso, arms, and uniform are protected from contamination.
The gown is the largest piece of PPE and provides the primary barrier; securing it first establishes foundational body coverage.
3
Don the N95 respirator, securing the elastic headbands, and perform a seal check.
The respiratory tract is protected from airborne infectious particles.
The respirator requires precise strap placement around the head and a critical seal check, which is significantly easier to accomplish before bulky eye protection is applied.
4
Place the face shield over the eyes and face, adjusting the headband to fit securely.
The eyes and face are protected from aerosolized respiratory secretions and procedural splashes.
The face shield rests externally over the respirator, preventing contaminated fluids from saturating the mask material.
5
Put on clean gloves and pull the edges carefully over the wrists of the isolation gown.
The hands are protected and the gap between the gown and gloves is completely sealed.
Applying gloves as the final step allows the nurse to pull them over the gown cuffs, creating a continuous barrier without exposing the wrists.
