Zorluk: OrtaStandard and Transmission-Based Precautions

A nurse preceptor is observing a newly graduated registered nurse (RN) implement infection control measures on a medical-surgical unit. Which of the following actions by the new RN demonstrate correct application of standard and transmission-based precautions? Select all that apply.

  1. Donning a gown and gloves before entering the room of a client with a confirmed norovirus infection.Cevap
  2. Applying a fit-tested N95 respirator prior to entering the room of a client diagnosed with measles (rubeola).Cevap
  3. C
    Removing the isolation gown and gloves in the hallway immediately after exiting the room of a client with Vancomycin-resistant enterococci (VRE).
  4. D
    Cleansing hands with an alcohol-based hand sanitizer after completing an assessment on a client with active Clostridioides difficile.
  5. Placing a standard surgical mask over the mouth and nose of a client with active pulmonary tuberculosis during transport for a diagnostic test.Cevap
  6. F
    Assigning a client with severe neutropenia to a negative-pressure room to protect them from healthcare-associated infections.

Cevap

The correct actions include donning a gown and gloves prior to entering a norovirus room, applying an N95 respirator for measles, and placing a standard surgical mask on a client with tuberculosis during transport.
Correct infection control practices require specific interventions based on the mode of transmission. Norovirus is spread via contact, requiring a gown and gloves upon room entry. Measles is transmitted via airborne droplet nuclei, necessitating a fit-tested N95 respirator. When a client with active pulmonary tuberculosis (an airborne pathogen) must leave their negative-pressure room for essential transport, they must wear a standard surgical mask to contain their respiratory secretions.

Adım Adım Çözüm

1
Evaluate the actions regarding personal protective equipment (PPE) for specific pathogens.
Norovirus requires contact precautions (gown and gloves upon entry). Measles requires airborne precautions (N95 respirator upon entry).
Matching the pathogen to the correct isolation tier is the primary step in preventing transmission.
2
Analyze the procedure for transporting a client on airborne precautions.
A client with active tuberculosis must wear a standard surgical mask during transport.
The surgical mask contains the client's respiratory droplets and droplet nuclei, protecting the environment and staff outside the isolation room.
3
Review the principles of PPE removal and environmental safety.
PPE must be removed inside the isolation room (VRE), hands must be washed with soap and water for spore-forming bacteria (C. difficile), and immunocompromised clients need positive-pressure rooms.
Improper removal of PPE, incorrect hand hygiene, and wrong room pressurization contribute to healthcare-associated infections.
