Zorluk: OrtaStandard and Transmission-Based Precautions

An ambulatory care nurse is evaluating a client in a crowded clinic reception area. The client reports a persistent cough for four weeks, recent episodes of coughing up blood, and drenching night sweats. Arrange the following nursing actions in the correct priority sequence from first to last.

  1. 1Provide a standard surgical mask for the client to wear immediately.
  2. 2Escort the client to a negative-pressure airborne infection isolation room.
  3. 3Don a fit-tested N95 respirator prior to conducting the physical assessment.
  4. 4Obtain the required sputum sample for acid-fast bacilli testing.
  5. 5Explain the specific airborne isolation protocols to the client.

Cevap

The correct sequence prioritizes public safety through immediate source control (masking the client), followed by environmental isolation, provider protection (N95), diagnostic testing, and finally, client education.
In any triage setting, infection control follows a strict hierarchy of safety: protect the masses (source control via client masking), isolate the threat (move to negative-pressure room), protect the individual worker (don N95), perform clinical interventions (sputum collection), and finally address psychosocial/educational needs.

Adım Adım Çözüm

1
Identify the transmission risk based on the clinical presentation.
Recognize symptoms (hemoptysis, night sweats, prolonged cough) as highly suspicious for active pulmonary tuberculosis, requiring Airborne Precautions.
Accurate pathogen identification drives the correct selection of infection control protocols.
2
Prioritize source control.
Provide the client with a standard surgical mask.
Placing a standard mask on the infectious source immediately stops the spread of droplet nuclei into the crowded reception area.
3
Establish environmental isolation.
Move the client to a negative-pressure airborne infection isolation room (AIIR).
Removing the client from the public area minimizes exposure risk to other waiting clients and unprotected staff.
4
Protect the healthcare worker.
The nurse dons a fit-tested N95 respirator.
Before entering the AIIR for prolonged contact or assessment, the nurse must protect themselves from airborne transmission.
5
Perform high-risk clinical tasks safely.
Collect the sputum sample for acid-fast bacilli (AFB).
Aerosol-generating procedures or tasks that induce coughing must be done in a controlled environment while wearing an N95 respirator.
6
Provide nursing education.
Explain the isolation protocols to the client.
Education is essential for compliance but must be sequenced after all acute safety and containment measures are established.

Anahtar Kavram

Airborne transmission prevention relies on immediate source control followed by environmental isolation.
