How do transmission-based precautions differ from standard precautions?

• A. They replace standard precautions entirely.
• B. They are only for airborne infections and not contact or droplet.
• C. They do not require PPE beyond gloves.
• D. They add measures for suspected or confirmed infections beyond standard precautions.

Answer: (D)

Transmission-based precautions are the extra steps used when a patient has or is suspected of having an infection that can spread in specific ways. They sit on top of standard precautions, which are used for all patients, and they don’t replace them. The key idea is that, beyond the baseline practices like hand hygiene and basic PPE, you add measures tailored to how the infection travels—airborne, droplet, or contact. Depending on the route, that can mean using masks or respirators, gowns, eye protection, or placing the patient in a special room. So the best description is that these precautions add targeted measures for suspected or confirmed infections beyond standard precautions.
