Transmission and Emergency Safety — NCLEX-PN

Droplet precautions guard against infections spread by large respiratory droplets that travel only a short distance, roughly 3–6 feet, before falling. Wear a surgical mask when within that range; examples include influenza, pertussis, and bacterial meningitis. A private room or cohorting clients with the same infection reduces droplet exposure, and the client wears a mask when transported.

Airborne precautions guard against infections carried on tiny particles that stay suspended in the air and travel long distances. The classic examples — tuberculosis, measles, and varicella — require a negative-pressure (airborne infection isolation) room and a fitted N95 respirator. Keep the door closed at all times and don the N95 every time you enter the room.

Contact precautions guard against infections spread by direct touch or by contaminated surfaces and equipment. Wear a gown and gloves on entering the room; common examples include MRSA, C. difficile, and scabies. Dedicate equipment such as the stethoscope and blood pressure cuff to that room and disinfect anything that must leave it.

PPE (personal protective equipment) creates a barrier between the caregiver and infectious agents. Don it in order — gown, then mask or respirator, then goggles, then gloves — and doff in reverse, removing the contaminated gloves first. The correct sequence matters because it prevents the nurse from self-contaminating while taking equipment off, protecting both staff and client.

Sharps are needles, scalpels, lancets, and other objects that can puncture the skin and transmit bloodborne pathogens. Never recap a used needle; dispose of it directly into a puncture-resistant sharps container, and activate any built-in safety device. Needlestick injuries must be reported immediately and the source client tested per policy so post-exposure prophylaxis can be started if needed.

A facility fire is an emergency requiring an immediate, organized response that keeps people safe first. Follow RACE — Rescue anyone in danger, Activate the Alarm, Contain the fire by closing doors, then Extinguish or Evacuate — and remember the order puts people before property. For the extinguisher itself, use PASS: Pull the pin, Aim at the base of the flames, Squeeze the handle, and Sweep side to side.

Oxygen is a therapeutic gas that, while not flammable itself, vigorously supports combustion and is therefore a fire hazard in clinical settings. Allow no open flames, smoking, or electric razors near oxygen, and post “no smoking — oxygen in use” signs on the door and at the bedside. Even static electricity from synthetic fabrics can ignite an oxygen-enriched environment, so the area must be controlled.
