Zorluk: OrtaStandard and Transmission-Based Precautions

A healthcare provider is preparing to enter the negative-pressure isolation room of a client with suspected severe acute respiratory syndrome (SARS). The client requires airborne and contact precautions, along with standard precautions and eye protection. Arrange the following steps for donning personal protective equipment (PPE) in the correct chronological sequence according to Centers for Disease Control and Prevention (CDC) guidelines.

  1. 1Perform hand hygiene using soap and water or an alcohol-based hand rub.
  2. 2Put on the isolation gown and secure the ties at the neck and waist.
  3. 3Apply a NIOSH-approved N95 respirator and perform a user seal check.
  4. 4Place goggles or a face shield over the eyes and face.
  5. 5Don clean gloves and extend them to cover the cuffs of the isolation gown.

Cevap

The correct sequence is: perform hand hygiene, put on the isolation gown, apply the N95 respirator, place the eye protection, and finally don the gloves.
The correct sequence (Hand hygiene, Gown, Respirator, Eye protection, Gloves) strictly follows established CDC infection control guidelines designed to ensure healthcare worker safety, maintain the integrity of the PPE barrier, and prevent contamination.

Adım Adım Çözüm

1
Determine the starting action required for any aseptic or clean procedural protocol.
Perform hand hygiene.
Hands must be clean before touching and applying clean PPE to prevent transfer of pathogens.
2
Sequence the primary body coverage layer.
Put on the isolation gown.
The gown covers the torso and arms, creating the primary barrier that other items will overlap.
3
Sequence the respiratory and facial protection.
Apply the N95 respirator first, followed by eye protection.
The respirator must secure tightly to the face for an effective seal; applying eye protection first would disrupt the respirator straps and seal.
4
Determine the final step to secure the extremity barrier.
Don gloves and pull them over the gown cuffs.
Applying gloves last allows them to overlap the gown cuffs, creating a seamless seal at the wrists.

Anahtar Kavram

The CDC standardized sequence for donning PPE is: Hand Hygiene -> Gown -> Mask/Respirator -> Goggles/Face Shield -> Gloves. This sequence maximizes barrier efficacy and prevents contamination of the equipment.
