Question

match the following descriptions with the correct precaution types:

1. patient in negative pressure room with door closed
2. for organisms spread by contact with contaminated surfaces or infectious substances
3. protects against diseases transmitted by coughing or vomiting
4. only facial protection (eye and mouth) is required

options:

• airborne precautions
• contact precautions
• contact and droplet precautions
• droplet precautions

Explanation:

Analyze negative pressure room requirement

Using the Airborne Precautions knowledge point, airborne pathogens remain suspended in the air. They require a negative pressure room with a closed door to prevent contaminated air from escaping.

Analyze contact transmission description

Organisms spread by touching contaminated surfaces or infectious substances require Contact Precautions to block physical transmission pathways.

Analyze coughing and vomiting protection

Coughing and vomiting generate both large droplets and potential surface contamination. This dual transmission route requires Contact and Droplet Precautions.

Analyze facial protection requirement

Using the Droplet Precautions knowledge point, pathogens transmitted by large respiratory droplets travel short distances. They require only facial protection (eye and mouth) during close contact.

Answer:

No.	Description	Precaution Type
2	For organisms spread by contact with contaminated surfaces or infectious substances	Contact Precautions
3	Protects against diseases transmitted by coughing or vomiting	Contact and Droplet Precautions
4	Only facial protection (eye and mouth) is required	Droplet Precautions
