CRCST Chapter 7 Practice Test: Point-of-Use Treatment and Transport

Point-of-use treatment begins the reprocessing cycle at the moment a surgical instrument is used. This chapter explains why instruments must be kept moist after use — dried blood and tissue form biofilm that resists even aggressive cleaning. Proper point-of-use treatment includes wiping gross soil from instruments during the procedure, applying enzymatic foam or gel sprays, keeping instruments moist with wet towels in transport containers, and never allowing them to air dry. The chapter covers transport container selection, biohazard labeling requirements, traffic patterns to prevent cross-contamination between clean and soiled areas, and documentation requirements. Timely and proper treatment at the point of use dramatically reduces the cleaning burden downstream and helps ensure sterilization success.
