What is the difference between standard precautions and isolation precautions (contact and droplet)?

• A. Standard precautions apply to all residents; isolation precautions add PPE and rooming requirements based on risk of transmitting specific pathogens (contact for direct/indirect contact; droplet for respiratory droplets).
• B. Isolation uses only gloves.
• C. Standard precautions are optional.
• D. Isolation is only for airborne.

Answer: (A)

Standard precautions are the baseline infection prevention measures used with all residents to prevent transmission, regardless of infection status. They include hand hygiene before and after patient contact, gloves when touching blood or bodily fluids, and additional PPE (gown, mask, eye protection) as exposure risk requires, along with safe injection practices and environmental cleaning. Isolation precautions are added when a resident has a known or suspected infection that could spread to others. They’re chosen based on how the pathogen moves: for infections spread by direct or indirect contact, contact precautions are used—gloves and a gown for staff, with dedicated or limited shared equipment and a private room or cohorting when possible. For infections spread through respiratory droplets, droplet precautions are used—a mask (and eye protection as needed) for anyone entering the room, and again usually a private room if feasible. The other statements aren’t accurate because isolation isn’t limited to gloves alone, standard precautions aren’t optional, and isolation isn’t restricted only to airborne diseases; it includes contact and droplet methods (and others in different contexts).
