CER Practice Test – Pass the Certified Endoscope Reprocessor Exam (2025 Guide)

The step in the cleaning process that involves submerging the scope in an enzymatic solution is the initial soaking phase. During this stage, endoscopes are immersed in a solution containing enzymes specifically designed to break down organic materials, such as blood, tissue, and other residues left on the instruments after procedures. This enzymatic action is essential because it helps dislodge contaminants and prepares the endoscope for further cleaning tasks.

Establishing an effective initial soaking routine is critical to ensuring that subsequent cleaning steps can be performed efficiently and effectively. This phase allows the enzymatic solution to penetrate and emulsify debris, which is particularly important for intricate instruments like endoscopes that have complex designs and narrow channels. Proper initial soaking ultimately enhances the overall disinfection and sterilization process, ensuring better patient safety and instrument longevity.
