CH Safety & Infection Control 4

Question 1

What is the minimum contact time (dwell time) required for a disinfectant to be effective on a surface?

Accepted Answer

The time specified on the EPA-registered product label

Answer

Disinfectants must remain wet on a surface for the contact time listed on the product label to achieve the stated efficacy against pathogens.

Question 2

Which of the following best describes 'standard precautions' as applied to colonic hydrotherapy?

Accepted Answer

Treating all blood, body fluids, and mucous membranes from every client as potentially infectious

Answer

Standard precautions assume all clients may be infectious, eliminating the need for a known diagnosis before protective measures are applied.

Question 3

When cleaning colonic hydrotherapy equipment between clients, what is the correct order of steps?

Accepted Answer

Clean (remove organic matter), then disinfect

Answer

Cleaning to remove organic matter must precede disinfection because organic material inactivates many disinfectants and prevents them from reaching pathogens.

Question 4

A new therapist asks about re-using a single-use speculum for a second client after high-level disinfection. What is the correct response?

Accepted Answer

Single-use devices are never to be reprocessed or reused on any client under any circumstances

Answer

FDA regulations strictly prohibit reprocessing or reusing devices labeled 'single-use only' due to risks of infection transmission and device integrity failure.

Question 5

What is the function of the backflow prevention device on colonic hydrotherapy equipment?

Accepted Answer

To prevent contaminated water from flowing back into the potable water supply

Answer

A backflow preventer (e.g., vacuum breaker) protects the public water supply from cross-contamination with fecal matter or contaminated equipment water.
