What is the main purpose of a surgical scrub sink with foot or knee controls?

• A. To prevent hand contamination by avoiding contact with faucet handles
• B. To speed up scrubbing time
• C. To improve water pressure
• D. To reduce sink maintenance

Answer: (A)

Preventing hand contamination during the scrub rinse. After a sterile hand and arm scrub, you need to rinse without touching any faucet surfaces, which could transfer microbes to your clean hands or gloves. Foot or knee controls let water flow and adjust pressure without using your hands, preserving the sterility of the scrubbed area until you are fully gloved and ready for the procedure. While faster scrubbing, higher water pressure, or easier maintenance aren’t the primary goals, they don’t address the key need to avoid recontaminating sterile hands or arms during the rinse.
