Question

Difficulty: MediumStandard and Transmission-Based Precautions

The charge nurse is reviewing transmission-based precautions for four newly admitted clients. Match each client's clinical presentation to the appropriate isolation protocol required for their care.

  • A client presenting with fever, nuchal rigidity, and suspected Neisseria meningitidis infection.Implement Droplet Precautions: Place in a private room and wear a standard surgical mask when within 3 feet of the client.
  • A client presenting with fever, coryza, and a maculopapular rash suggestive of rubeola.Implement Airborne Precautions: Place in a negative-pressure room and don an N95 respirator prior to entry.
  • A client with profuse, watery diarrhea who recently completed a prolonged course of broad-spectrum antibiotics.Implement Contact Enteric Precautions: Don a gown and gloves upon entry and perform hand hygiene exclusively with soap and water.
  • A client with a heavily draining sacral pressure ulcer colonized with vancomycin-resistant Enterococcus (VRE).Implement Contact Precautions: Don a gown and gloves upon entry and perform hand hygiene using an alcohol-based hand rub.

Answer

Neisseria meningitidis matches with Droplet Precautions; rubeola (measles) matches with Airborne Precautions; post-antibiotic diarrhea (C. diff) matches with Contact Enteric Precautions (soap and water); VRE matches with Standard Contact Precautions (alcohol-based rub).
The correct pairings accurately reflect the specific pathogen transmission routes and their corresponding infection control requirements. Meningitis is spread by large droplets, requiring a standard surgical mask. Measles is airborne, requiring an N95 mask and an isolation room. Suspected C. diff requires contact precautions with a mandatory modification for soap and water handwashing because its spores resist alcohol. Finally, VRE requires contact precautions but can safely be managed with standard alcohol-based hand hygiene.

Step-by-Step Solution

1
Identify the primary mode of transmission for Neisseria meningitidis.
It is transmitted via large respiratory droplets, necessitating Droplet Precautions.
Large droplets do not travel far, so a standard surgical mask is sufficient when close to the client.
2
Identify the primary mode of transmission for rubeola (measles).
It is transmitted via small airborne particles, necessitating Airborne Precautions.
Small particles remain suspended in the air, requiring a negative-pressure room and a specialized N95 respirator.
3
Evaluate the clinical presentation of the client with post-antibiotic diarrhea.
The presentation is highly suspicious for Clostridioides difficile, which requires Contact Enteric Precautions.
C. diff spores are not eradicated by alcohol; therefore, mechanical removal using soap and water is essential.
4
Determine the required precautions for a draining wound colonized with VRE.
VRE requires standard Contact Precautions.
VRE is spread by contact, but unlike C. diff, it is effectively killed by standard alcohol-based hand sanitizers.
