Question

Difficulty: MediumStandard and Transmission-Based Precautions

Four clients arrive simultaneously at the emergency department triage desk. Based on the presenting clinical manifestations, which client requires the highest priority for immediate placement in an airborne infection isolation (negative-pressure) room?

  1. A client presenting with a generalized maculopapular rash, high fever, and coryzaAnswer
  2. B
    A client presenting with severe nuchal rigidity, photophobia, and an abrupt fever
  3. C
    A client presenting with severe paroxysmal coughing spasms and posttussive emesis
  4. D
    A client presenting with frequent, foul-smelling liquid stools and abdominal cramping

Answer

The client presenting with a generalized maculopapular rash, high fever, and coryza.
The correct answer identifies the client exhibiting symptoms of rubeola (measles): a generalized maculopapular rash, high fever, and coryza. Measles is a highly contagious disease transmitted via airborne droplet nuclei. Because these particles remain infectious and suspended in the air over long distances, this client MUST be placed in an airborne infection isolation room (negative-pressure room) to prevent facility-wide transmission.

Step-by-Step Solution

1
Analyze the facility requirement specified in the question.
The prompt asks which client requires an airborne infection isolation room, which features negative air pressure.
Identifying the required isolation tier is the first step in matching a client to the correct room.
2
Evaluate the clinical manifestations of each client to suspect the underlying pathogen and its transmission route.
The maculopapular rash and coryza indicate measles (airborne); nuchal rigidity indicates meningitis (droplet); paroxysmal cough indicates pertussis (droplet); foul-smelling liquid stools indicate C. difficile (contact).
Nurses must use clinical judgment during triage to initiate presumptive isolation precautions before a definitive medical diagnosis is made.
3
Prioritize the client who requires the negative-pressure room based on the transmission route.
The client with suspected measles must be prioritized for the negative-pressure room to prevent airborne transmission.
Airborne pathogens can remain suspended in the air over long distances and require specialized room exhaust systems to protect the facility.

Key Concept

Airborne precautions are required for illnesses transmitted by small droplet nuclei that remain suspended in the air (e.g., rubeola/measles, varicella, tuberculosis), necessitating placement in a negative-pressure room.
