What is the standard by which things are measured or compared?

• A. Bloodborne
• B. Baseline
• C. Biohazards
• D. Behavioral health-care facility

Answer: (B)

A baseline is the starting reference point used to measure and compare future data. It’s what you record before making changes, so you can see how outcomes evolve over time. In infection control, you might establish a baseline for metrics such as hand hygiene compliance, environmental cleanliness, or infection rates. After implementing interventions, you compare new measurements to this baseline to determine whether things have improved, stayed the same, or worsened. This makes it possible to quantify impact and guide further action.

The other terms don’t describe a reference point for measurement: bloodborne refers to a type of pathogen transmission, biohazards are hazards to health, and a behavioral health-care facility is a facility type.
