Difficulty: MediumStandard and Transmission-Based Precautions

Match each client's clinical presentation to the appropriate transmission-based isolation precautions required for their care.

  • A client presenting with coryza, Koplik spots, and a descending maculopapular rash.Airborne Precautions
  • A client experiencing multiple episodes of foul-smelling, watery diarrhea after broad-spectrum antibiotic therapy.Contact Precautions (Enteric)
  • A client exhibiting severe, paroxysmal coughing episodes that end with a high-pitched inspiratory sound.Droplet Precautions
  • A client with an open surgical incision producing copious purulent drainage.Contact Precautions (Standard)

Answer

Measles (coryza/Koplik spots) pairs with Airborne Precautions. Clostridioides difficile (watery diarrhea post-antibiotics) pairs with Contact Precautions (Enteric). Pertussis (paroxysmal coughing) pairs with Droplet Precautions. A draining surgical wound pairs with standard Contact Precautions.
Each clinical presentation is correctly matched to the specific transmission-based precaution required to prevent the spread of the suspected pathogen. Airborne is needed for measles, Contact (Enteric) for C. difficile, Droplet for pertussis, and standard Contact for a heavily draining wound.

Step-by-Step Solution

1
Identify the underlying infectious pathogen or condition described in each clinical presentation.
The presentations correspond to measles, C. difficile, pertussis, and a heavily draining wound.
Accurate pathogen identification is the prerequisite for determining the correct isolation category.
2
Determine the primary mode of transmission for each identified condition.
Measles is airborne; C. difficile is fecal-oral (spore-forming); pertussis is via respiratory droplets; draining wounds pose a direct contact risk.
Transmission-based precautions are specifically designed to interrupt the pathogen's primary route of spread.
3
Select the appropriate isolation category that mitigates the specific mode of transmission.
Measles requires Airborne, C. difficile requires Contact (Enteric), Pertussis requires Droplet, and the draining wound requires Contact.
Matching the transmission route to the CDC-recommended precautions ensures a safe care environment.

Key Concept

Selecting the correct transmission-based precautions requires identifying the pathogen's mode of transmission (airborne, droplet, or contact) and applying the appropriate barrier methods.
