Sharp metallic implements may be sanitized with:

  1. Kerosene

  2. Dry heat

  3. 70% alcohol

  4. Hydrogen peroxide

The correct answer is: 70% alcohol

Option A Kerosene is flammable and should not be used to sanitize sharp metallic implements. It can also be harmful if not handled properly. Option B: While dry heat can effectively sanitize sharp metallic implements, it may also cause the implements to rust or corrode over time. Option D: While hydrogen peroxide can be used to clean and disinfect surfaces, it is not recommended for sanitizing sharp metallic implements as it may cause discoloration or damage to the implements. Therefore, option C, 70% alcohol, is the best choice as it is effective at killing germs and bacteria on metallic implements without causing damage or discoloration.
