Question

which of the following is an advantage of using alcohol - based gel? it takes less time to use than washing with soap and water. it removes gross contamination better than soap and water does. its protective nature reduces the need for frequent handwashing. it provides adequate protection before surgical applications.

Explanation:

• For the option "It takes less time to use than washing with soap and water": Alcohol - based gel can be applied and rubbed in quickly, while handwashing with soap and water requires wetting hands, applying soap, lathering, rinsing, and drying, which takes more time.
• For "It removes gross contamination better than soap and water does": Soap and water are better at removing gross (visible) contamination as the physical action of washing and rinsing helps to remove dirt and debris, while alcohol - based gel is more for killing microbes on relatively clean hands.
• For "Its protective nature reduces the need for frequent handwashing": Alcohol - based gel is for sanitizing, not a substitute for handwashing when hands are dirty or contaminated, and frequent handwashing (or sanitizing when appropriate) is still needed.
• For "It provides adequate protection before surgical applications": Surgical applications require sterile conditions, and soap and water with proper scrubbing (surgical handwashing) is necessary as alcohol - based gel is not sufficient for the level of sterility needed before surgery.

Answer:

A. It takes less time to use than washing with soap and water.
