Zorluk: ZorStandard and Transmission-Based Precautions

A practical nurse is conducting environmental rounds on a medical-surgical unit to monitor adherence to infection control standards. Which observed action demonstrates correct application of transmission-based precautions?

  1. A transporter places a standard surgical mask over the nose and mouth of a client with active pulmonary tuberculosis prior to a transfer to the radiology department.Cevap
  2. B
    An unlicensed assistive personnel removes a contaminated isolation gown and gloves in the hallway immediately after exiting a contact precaution room.
  3. C
    A charge nurse assigns a newly admitted client with a draining methicillin-resistant Staphylococcus aureus (MRSA) wound to share a room with a client recovering from extensive burns.
  4. D
    A respiratory therapist dons a fit-tested N95 respirator before entering the room of a client diagnosed with seasonal influenza to perform a routine assessment.

Cevap

A transporter places a standard surgical mask over the nose and mouth of a client with active pulmonary tuberculosis prior to a transfer to the radiology department.
The correct action involves placing a standard surgical mask on a client with active pulmonary tuberculosis when they leave their negative-pressure room. While healthcare workers must wear a fit-tested N95 respirator to protect themselves from airborne droplet nuclei, the client only needs a standard surgical mask to serve as source control, trapping respiratory secretions before they enter the environment.

Adım Adım Çözüm

1
Analyze the transmission mode and specific isolation requirements for each pathogen mentioned in the scenarios.
Tuberculosis requires Airborne Precautions; MRSA requires Contact Precautions; Influenza requires Droplet Precautions.
Correctly identifying the transmission mode is the foundational step in determining appropriate infection control interventions.
2
Evaluate the personal protective equipment (PPE) requirements for client transport versus staff entry.
Staff require an N95 respirator to enter a tuberculosis room, but the client only requires a standard surgical mask to contain respiratory secretions during necessary transport.
There is a critical distinction between protecting healthcare workers from airborne particles in the environment and containing the particles at the source (the client).
3
Assess the remaining scenarios for procedural safety and appropriate cohorting logic.
Removing PPE in the hallway breaches Contact Precautions; cohorting an infected client with a burn victim endangers a susceptible host; and wearing an N95 for routine influenza care is an incorrect over-application of PPE.
Infection control requires strict adherence to PPE sequences, doffing locations, and protecting immunocompromised or susceptible clients from cross-contamination.
