A nurse is reviewing transmission-based precautions (isolation) with a group of student nurses. Which of the following statements by the student nurses indicate understanding droplet precautions?

Rationale: A. "Droplet precautions are used for micro-organisms that remain suspended in the air for a long time and long distances.": This describes airborne transmission rather than droplet transmission. Droplet particles are heavier, fall quickly, and do not remain suspended. B. "I should put on a gown before entering the room of a patient on droplet precautions.": A gown is not routinely required for droplet precautions unless contact with secretions or bodily fluids is expected. The key requirement for droplet precautions is wearing a mask. C. "Droplet precautions are used for micro-organisms that are transmitted less than 3 feet from the infected patient.": Droplet transmission occurs when respiratory droplets travel a short distance—typically 3 to 6 feet—before falling. This indicates understanding of how pathogens like influenza and meningococcal disease spread, guiding the correct use of a surgical mask. D. "I should wear an N95 respirator before entering the room of a patient on droplet precautions.": N95 respirators are required for airborne infections where particles remain suspended and travel long distances. Using an N95 for droplet precautions is unnecessary.
