SPD - Sterile Processing Department Technician Decontamination and Cleaning Processes Questions and Answers

Question 1

A Sterile Processing technician is manually cleaning a set of surgical instruments from an orthopedic procedure. Which of the following actions is MOST critical to perform first to ensure effective cleaning?

Accepted Answer

Disassemble multi-part instruments and open all hinged clamps.

Answer

Disassembling instruments and opening box locks and hinges is the crucial first step in manual cleaning. This action exposes all surfaces, including crevices and joints where bioburden is likely to accumulate, to the cleaning solution and manual friction, ensuring a thorough decontamination process.

Question 2

The process of cavitation, which uses microscopic bubbles imploding to dislodge soil from instrument surfaces, is characteristic of which cleaning method?

Accepted Answer

Ultrasonic Cleaner

Answer

Ultrasonic cleaners work by generating high-frequency sound waves that create microscopic bubbles in the cleaning solution. These bubbles implode, a process called cavitation, creating a powerful scrubbing action that removes soil from hard-to-reach areas like joints, crevices, and lumens.

Question 3

When preparing to load a washer-disinfector, which of the following is an INCORRECT practice?

Accepted Answer

Ensuring hinged instruments are in the closed and locked position.

Answer

Hinged instruments must be in an open and unratcheted position when placed in a washer-disinfector. This allows the water and detergent spray to reach and clean all surfaces, especially the critical box lock and jaw areas where bioburden can be trapped.

Question 4

A new SPD technician is working in the decontamination area. They notice that instruments coming out of the manual cleaning sink still have dried blood in the serrations after being scrubbed. What is the MOST likely cause of this issue?

Accepted Answer

The water temperature was too high, causing blood to coagulate.

Answer

Using hot water for the initial rinse or wash of proteinaceous soils like blood can cause it to coagulate (cook) onto the instrument surface, making it much more difficult to remove. Cleaning should begin with cool or tepid water.

Question 5

Which of the following is considered the first step in the decontamination process, beginning immediately after a surgical procedure?

Accepted Answer

Point-of-use cleaning.

Answer

The decontamination process begins at the point of use. Instruments should be wiped to remove gross soil and kept moist with a pre-treatment spray or damp towel to prevent blood and bioburden from drying before they are transported to the SPD.
