Which additional indicators function as supporting indicators along with chemical and biological indicators?

• A. Internal and external integrators
• B. Visual indicators
• C. Humidity indicators
• D. Temperature indicators

Answer: (A)

The main idea here is how sterilization monitoring uses more than just a single type of indicator. Along with chemical and biological indicators, integrators serve as additional, or supporting, indicators because they summarize whether the whole cycle delivered the required exposure. Internal and external integrators are placed inside the load and outside it, respectively, to verify that the conditions reached the entire package and were maintained through the cycle. They combine information about time, temperature, and other critical parameters, giving a quick pass/fail sense of whether the process likely met the necessary exposure. This makes them the best choice because they provide a broader check than individual indicators. Visual indicators, humidity indicators, and temperature indicators each track a specific aspect or condition, but they don’t collectively confirm that the entire load experienced the correct sterilization exposure.
