An infection control nurse is reviewing the electronic health records of newly admitted clients to ensure appropriate transmission-based protocols are active. Correlate each client's specific clinical presentation with the precise isolation requirements necessary for their care.
- Immunocompromised client exhibiting a localized dermatomal rash with fluid-filled vesiclesAirborne and Contact precautions (maintain until lesions are completely crusted)
- Client experiencing frequent, foul-smelling liquid stools following a prolonged course of broad-spectrum antibioticsContact precautions with strict enteric hand hygiene utilizing soap and water
- Young adult presenting with sudden onset of fever, nuchal rigidity, and a non-blanching petechial rashDroplet precautions (may be discontinued after 24 hours of effective antimicrobial therapy)
- Adult with a persistent cough, hemoptysis, night sweats, and an apical cavitary lesion on chest imagingAirborne precautions (requires placement in a negative-pressure isolation room)
Answer
The immunocompromised client with a localized vesicular rash matches Airborne and Contact precautions; the client with post-antibiotic liquid stools matches Contact precautions with soap and water; the client with nuchal rigidity and petechial rash matches Droplet precautions for 24 hours; and the client with a cavitary lung lesion matches Airborne precautions in a negative-pressure room.
Each clinical presentation directly dictates a specific infection control protocol based on the pathogen's mode of transmission, the patient's immune status, and the physical properties of the infectious agent (such as spore formation).
