Quizplus · Accepted Answer

Alcohol disinfectants in the health care setting refer to either ethyl alcohol or isopropyl alcohol. Neither is considered a high-level disinfectant as a single agent, they are not sporicidal, and they do not penetrate protein-rich materials. Their activity drops when diluted below 50% concentration. Alcohols are inactivated by protein and can damage rubber, plastics, and the shellac mounting of lensed instruments. Alcohol wipes are a good choice for disinfecting small surfaces, such as medication vial tops. Alcohols are also useful as surface disinfectants for stethoscopes, ventilators, and manual ventilation bags.
