Difficulty: Very hardStandard and Transmission-Based Precautions

An infection control committee is evaluating nursing adherence to complex transmission-based precautions across various specialty units. Match each high-acuity client scenario on the left with the specific, evidence-based isolation intervention required for their safe management on the right.

  • A client with suspected pulmonary tuberculosis requiring transport to radiology for a diagnostic CT scan.Apply a standard medical-surgical mask to the client; transporting personnel do not require respiratory protection during the physical transfer.
  • A client with a localized herpes zoster rash on the right flank who is currently undergoing aggressive induction chemotherapy.Initiate airborne and contact precautions, requiring all entering personnel to wear an N95 respirator, gown, and gloves.
  • A client mechanically ventilated for severe acute respiratory distress syndrome secondary to a confirmed novel coronavirus infection.Implement airborne, contact, and eye precautions, utilizing an airborne infection isolation environment due to aerosol-generating interventions.
  • A client with confirmed meningococcal pneumonia who has completed 18 hours of continuous intravenous ceftriaxone therapy.Maintain droplet precautions, requiring healthcare personnel to wear a surgical mask when within 3 feet, until 24 hours of antimicrobial therapy are complete.

Answer

The client with TB should wear a mask during transport without staff needing an N95. The immunocompromised client with localized zoster requires airborne and contact precautions. The ventilated coronavirus client requires airborne, contact, and eye precautions in an AIIR. The meningococcal pneumonia client must maintain droplet precautions until completing 24 full hours of antibiotics.
The correct matches synthesize advanced knowledge of transmission-based precautions, demanding the application of specific clinical nuances such as patient immune status, procedural risks (aerosol generation), medication timing, and transport protocols. Applying these rules exactly as prescribed by national guidelines prevents healthcare-associated transmission.

Step-by-Step Solution

1
Analyze the transport requirements for the client with pulmonary tuberculosis.
The client must wear a standard mask to contain secretions, allowing transporting staff to safely transfer the client without an N95 respirator.
Standard protocol for airborne diseases prioritizes containing the source by masking the client during transport outside an isolation room.
2
Evaluate the immune status of the client with localized herpes zoster.
Because the client is undergoing induction chemotherapy, they are severely immunocompromised and require airborne and contact precautions.
Immunocompromised individuals are at high risk for disseminated disease, meaning the virus can spread via airborne routes rather than remaining localized to a dermatome.
3
Assess the procedural risks for the client with a novel coronavirus infection.
Mechanical ventilation is an aerosol-generating procedure, requiring an upgrade to airborne, contact, and eye precautions.
Aerosol-generating procedures create fine droplet nuclei that remain suspended in the air, necessitating an N95 respirator and an airborne infection isolation environment.
4
Determine the duration of isolation for the client with meningococcal pneumonia.
Droplet precautions must be maintained because the client has only received 18 hours of antibiotics.
Current CDC guidelines stipulate that droplet precautions for Neisseria meningitidis must continue until the client has received a full 24 hours of effective antimicrobial therapy.
