Zorluk: OrtaInfection Control and Hospital-Acquired Conditions

Match each clinical scenario of a newly admitted patient to the most appropriate initial infection control isolation tier required.

  • A 30-year-old patient with severe paroxysmal cough and posttussive emesis (suspected Bordetella pertussis)Droplet Precautions
  • A 65-year-old patient with a sacral ulcer growing Candida aurisContact Precautions
  • A 7-year-old unvaccinated patient with fever, coryza, and a descending maculopapular rash (suspected Measles)Airborne Precautions
  • A 40-year-old patient with HIV presenting with Cryptococcus neoformans meningitisStandard Precautions Only

Cevap

The correct matches are: Bordetella pertussis requires Droplet Precautions; Candida auris requires Contact Precautions; Measles requires Airborne Precautions; Cryptococcus neoformans requires only Standard Precautions.
Each pathogen requires specific transmission-based precautions corresponding to its route of spread. Pertussis spreads via large droplets, requiring Droplet Precautions. Candida auris is an emerging resistant fungus spread by contact, requiring Contact Precautions. Measles is a highly contagious virus spread by airborne aerosols, requiring Airborne Precautions. Cryptococcus is an environmental fungus not spread person-to-person, requiring only Standard Precautions.

Adım Adım Çözüm

1
Analyze the suspected Bordetella pertussis case.
Pertussis is primarily transmitted via large respiratory droplets.
Determines that Droplet Precautions are required to prevent transmission to healthcare personnel and other patients.
2
Analyze the Candida auris case.
Candida auris is a multidrug-resistant fungus known to heavily colonize skin and contaminate environmental surfaces.
Determines that strict Contact Precautions are necessary to prevent fomite-driven outbreaks.
3
Analyze the pediatric patient with coryza and descending rash (suspected measles).
Measles is transmitted via small airborne aerosolized particles that can remain suspended in the air.
Determines that Airborne Precautions (including negative pressure isolation and N95 respirators) are required.
4
Analyze the Cryptococcus neoformans meningitis case.
Cryptococcus is acquired via inhalation of environmental spores and is not communicable from person to person.
Determines that no specialized transmission-based precautions are needed beyond Standard Precautions.

Anahtar Kavram

Appropriate selection of transmission-based precautions (Airborne, Droplet, Contact, Standard) based on pathogen transmissibility.
