Zorluk: OrtaStandard and Transmission-Based Precautions

A registered nurse is planning care for a client who requires airborne precautions for confirmed active pulmonary tuberculosis. Which of the following infection control interventions should the nurse implement? Select all that apply.

  1. Admit the client to a private isolation room equipped with negative-pressure airflow.Cevap
  2. Instruct the client to wear a standard surgical mask when being transported outside the room for necessary procedures.Cevap
  3. Wear a fit-tested N95 respirator or powered air-purifying respirator (PAPR) when entering the client's room.Cevap
  4. D
    Remove the N95 respirator inside the client's room immediately before exiting.
  5. E
    Place a standard surgical mask on the client whenever healthcare personnel enter the room to provide care.
  6. F
    Keep the door to the client's room slightly ajar to promote continuous air circulation and filtration.

Cevap

The correct interventions are admitting the client to a negative-pressure isolation room, providing the client with a surgical mask during transport, and requiring staff to wear an N95 respirator or PAPR upon entry.
Active pulmonary tuberculosis requires airborne precautions because the pathogen is transmitted via small droplet nuclei that can remain suspended in the air over long distances. To safely manage this client, the nurse must ensure the client is placed in a private room with negative-pressure directional airflow, which prevents contaminated air from entering the general hospital environment. Furthermore, healthcare personnel must wear a fit-tested N95 respirator or a PAPR before entering the room to filter airborne particles. If the client must leave the room for an essential procedure, they must wear a standard surgical mask to serve as source control, which traps respiratory secretions and prevents the release of droplet nuclei into the air.

Adım Adım Çözüm

1
Identify the transmission route for the confirmed pathogen.
Active pulmonary tuberculosis is transmitted via small airborne droplet nuclei.
Knowing the transmission route dictates the required tier of transmission-based precautions (airborne).
2
Determine appropriate room placement and environmental controls.
A private, single-occupancy room with negative-pressure airflow is necessary.
Negative pressure ensures that air flows from the hallway into the room, preventing airborne particles from escaping into common areas.
3
Select appropriate personal protective equipment (PPE) for healthcare personnel.
Personnel must don a fit-tested N95 respirator or PAPR prior to entering the room.
Standard surgical masks do not filter out tiny airborne droplet nuclei effectively; N95s or PAPRs are required for adequate filtration.
4
Determine protocols for essential client transport.
The client must wear a standard surgical mask when exiting the isolation room.
The surgical mask acts as source control, trapping infectious particles expelled by the client before they can contaminate the hospital environment.

Anahtar Kavram

Airborne precautions for pulmonary tuberculosis require a negative-pressure isolation room, the use of an N95 respirator or PAPR by healthcare staff, and source control (a standard surgical mask on the client) during any necessary transport.
