24. According to the Centers for Disease Control and Prevention (CDC), hand hygiene with soap and water should be performed for at least how many seconds?
Answer: C
Hand hygiene with soap and water should be performed for at least 15 to 20 seconds.
Hand hygiene is crucial in preventing the spread of infections, and the CDC recommends that washing hands with soap and water should last for at least 15 to 20 seconds to effectively remove germs.
A) 2 to 5
This option is incorrect because washing hands for only 2 to 5 seconds is insufficient to eliminate most pathogens. The CDC guidelines clearly state that a longer duration is needed to ensure thorough cleaning.
B) 6 to 10
While 6 to 10 seconds is an improvement over the shortest duration, it still falls short of the recommended 15 to 20 seconds. This time frame is vital for effective hand hygiene practices.
C) 15 to 20
This is the correct answer as it aligns with CDC recommendations. Washing hands for 15 to 20 seconds is necessary to ensure that soap interacts with all surfaces of the hands, effectively removing dirt, viruses, and bacteria.
D) 45 to 60
This option is incorrect because it exceeds the CDC's recommended duration. While hand hygiene is important, washing for 45 to 60 seconds is generally not necessary and could lead to discomfort or skin irritation without additional benefits.
Conclusion
The recommendation of 15 to 20 seconds for handwashing is based on research indicating that this duration significantly reduces the presence of germs on hands. Options A, B, and D do not meet the CDC's guidelines, and therefore, the choice of C is the only answer that accurately reflects the necessary time for effective hand hygiene.
