Certified Endoscope Reprocessor (CER) Test 2025 – 400 Free Practice Questions to Pass the Exam

Question: 1 / 400

What should be done immediately after rinsing an endoscope?

Put it in a storage cabinet

Fill it with air

After rinsing an endoscope, it is essential to fill it with air to ensure that all channels and lumens are thoroughly dried. This step is crucial in preventing the growth of microbial contamination, which can occur if moisture is allowed to remain within the endoscope after rinsing. Air drying helps to displace any residual liquid and minimizes the risk of biofilm formation and subsequent infection when the endoscope is used on patients.

While methods like putting the endoscope in a storage cabinet or wrapping it in a sterile cloth might seem appropriate, they do not address the need for drying adequately. Similarly, drying with a towel could leave lint or particles behind, potentially contaminating the endoscope. Therefore, filling the endoscope with air immediately after rinsing is the best practice for maintaining its sterility and functionality.
