Rob is using hand rub when going into Mrs. Peterson's room. Mrs. Peterson asks Rob how he knows it is safe to proceed with his work once he has used hand rub. Rob replies:

A) It eliminates all bacteria instantly.
B) It provides long-lasting protection.
C) I need to wait for it to air dry.
D) It doesn't require any waiting time.

Answer :

Final answer:

Rob must wait for the hand rub to air dry to ensure it is effective at killing germs. Regular hand washing with soap and water is the best method for removing pathogens, and overuse of antimicrobial products can increase resistance.Hence option C is correct.

Explanation:

The question touches on the safety and efficacy of using hand rub as a method of infection control. When Rob uses hand rub and wonders if it's safe to proceed with his work, the most accurate answer is I need to wait for it to air dry. This is because hand rubs, which usually contain alcohol, are effective at killing many types of germs, but they need a short amount of time to evaporate and provide the maximum benefit.

Using hand rub is a quick, convenient supplement to hand washing, but it does not eliminate all bacteria instantly nor does it provide long-lasting protection without reapplication. Regular hand washing with soap and water remains the most effective way to remove pathogens, especially after sneezing, coughing, or handling contaminated surfaces. Overusing antimicrobial products can sometimes lead to increased resistance and other issues, so proper hand hygiene using the correct techniques is crucial.
