Instruments that penetrate the skin or mucous membranes have the ______ potential for transmitting infections.

Instruments that penetrate the skin or mucous membranes have the ______ potential for transmitting infections.

• A. Highest
• B. Moderate
• C. Low
• D. None

Answer: (A)

Instruments that penetrate skin or mucous membranes create the highest potential for transmitting infections because they bypass the body's protective barriers. When a sharp tool breaches these barriers, any pathogens in blood or bodily fluids can be carried directly into tissues or the bloodstream, significantly increasing the chance of infection. By contrast, instruments that only touch intact surfaces don’t provide that direct route into the body, so their risk is lower. Therefore, penetrating instruments pose the greatest transmission risk.
