Question 1

A patient is diagnosed with influenza. Which precautions should be added to standard precautions?

Accepted Answer

Droplet precautions

Answer

Influenza spreads via large respiratory droplets (>5 microns) that travel up to 3-6 feet, requiring droplet precautions including a surgical mask.

Question 2

A non-immune nurse must care for a patient with active varicella (chickenpox). Which combination of PPE is required?

Accepted Answer

N95 respirator, gown, and gloves

Answer

Varicella requires both airborne precautions (N95 respirator) and contact precautions (gown and gloves) because it spreads via airborne droplet nuclei and direct contact with lesions.

Question 3

Which condition requires droplet precautions rather than airborne precautions?

Accepted Answer

Meningococcal meningitis

Answer

Meningococcal meningitis spreads via large respiratory droplets and requires droplet precautions, while measles, TB, and varicella require airborne precautions.

Question 4

A neutropenic patient is admitted following chemotherapy. Which type of precautions is most appropriate for this patient?

Accepted Answer

Protective environment (reverse isolation)

Answer

Neutropenic patients require protective environment to shield them from environmental pathogens because their severely compromised immunity makes them highly susceptible to infection.

Question 5

A nurse is about to enter a room under airborne precautions. Which room characteristic must be confirmed before entering?

Accepted Answer

Negative pressure with at least 12 air changes per hour

Answer

Airborne precaution rooms require negative pressure with ≥12 air changes per hour to direct contaminated air inward and prevent its escape to hallways.
