Question: 1 / 400

Why is the removal of protein before disinfection or sterilization important in medical device reprocessing?

It prevents discoloration of the devices

Coagulated proteins can trap pathogens

The removal of protein before disinfection or sterilization is crucial because coagulated proteins can trap pathogens. When proteins remain on medical devices, they can form a barrier that protects microorganisms from the effects of disinfection and sterilization agents, making these processes less effective. If proteins are not removed prior to these procedures, the pathogens may survive, leading to potential infections and compromising patient safety.

In contrast, while discoloration of devices, handling ease, and weight reduction might have some relevance in other contexts, they do not fundamentally address the primary concern of ensuring that all microbial life is eliminated effectively. The main goal of reprocessing medical devices is to ensure they are safe for use, which hinges on completely removing any organic matter like proteins that could contribute to harboring pathogens.
