Difficulty: Very hardStandard and Transmission-Based Precautions

The infection control nurse is reviewing isolation protocols for four high-acuity clients. Match each client's clinical scenario to the most appropriate and comprehensive transmission-based precaution intervention required.

  • A client with localized herpes zoster (shingles) with vesicular lesions that cannot be completely contained by dressings.Implement Airborne and Contact Precautions, placing the client in a negative-pressure airborne infection isolation room (AIIR).
  • A client with confirmed Neisseria meningitidis meningitis who has received 18 hours of targeted intravenous antibiotic therapy.Maintain Droplet Precautions, requiring healthcare personnel to wear a surgical mask upon room entry.
  • A client with suspected Middle East Respiratory Syndrome (MERS) requiring an aerosol-generating procedure.Implement Standard, Contact, and Airborne Precautions, ensuring the use of an N95 respirator and eye protection.
  • A client with Clostridioides difficile colitis who requires transport to the radiology department for an urgent imaging study.Ensure the client wears a clean gown, notify the receiving department, and perform hand hygiene exclusively with soap and water.

Answer

Localized uncontainable zoster matches with Airborne/Contact in a negative-pressure room. Meningitis at 18 hours matches with maintaining Droplet Precautions. MERS matches with Airborne, Contact, and eye protection. C. difficile transport matches with clean gown, notifying the receiving department, and soap and water hand hygiene.
The correct pairings require a deep synthesis of infection control nuances. Localized herpes zoster that cannot be completely covered necessitates Airborne and Contact Precautions due to the severe aerosolization risk. Clients with Neisseria meningitidis remain contagious until a full 24 hours of antibiotics are completed, requiring continued Droplet Precautions at the 18-hour mark. MERS, particularly during aerosol-generating procedures, demands strict Airborne, Contact, and eye precautions. Finally, transporting a client with C. difficile requires preventing environmental shedding and strictly utilizing soap and water for hand hygiene, as the spores are highly resistant to alcohol-based sanitizers.

Step-by-Step Solution

1
Analyze the clinical presentation of the client with localized herpes zoster.
The lesions cannot be contained by dressings.
Uncontainable zoster lesions pose a significant airborne transmission risk, elevating the requirement from Standard/Contact to Airborne and Contact Precautions.
2
Evaluate the treatment duration for the client with Neisseria meningitidis.
The client has received only 18 hours of antibiotics.
Droplet Precautions must be maintained until exactly 24 hours of effective therapy have been completed, meaning precautions cannot yet be discontinued.
3
Identify the transmission risks associated with MERS during an aerosol-generating procedure.
The procedure poses a high risk of aerosolizing infectious viral particles.
MERS protocols require a combination of Standard, Contact, and Airborne Precautions, along with eye protection to fully protect mucosal surfaces.
4
Determine the appropriate transport and hygiene protocol for a client with Clostridioides difficile.
Transport requires containment, notification, and specific hand hygiene.
Bacterial spores are highly resistant to alcohol-based sanitizers; environmental containment and mechanical friction with soap and water are mandatory.
