Question 46

Washing hands with soap and water is essential to prevent the spread of C. difficile.

Hand hygiene, specifically washing hands with soap and water, is the most effective method to prevent the transmission of C. difficile spores, which are resistant to alcohol-based sanitizers.

A) wash hands with soap & water.

This option is correct because washing hands with soap and water physically removes C. difficile spores from the hands. Alcohol-based hand rubs are not effective against these spores, making proper handwashing critical in preventing their spread.

B) use alcohol hand-rub.

Using alcohol hand rub is incorrect in this context, as alcohol-based sanitizers do not effectively kill C. difficile spores. Therefore, relying solely on this method could lead to continued transmission of the infection.

C) avoid contact.

While avoiding contact can help reduce the risk of transmission, it is not a practical or comprehensive solution for preventing the spread of C. difficile. Hand hygiene is a more effective and feasible method for infection control.

D) encourage fluids.

Encouraging fluids does not directly address the prevention of C. difficile spread. This option is unrelated to hand hygiene practices and does not contribute to reducing the risk of transmission.

Conclusion

Washing hands with soap and water is the definitive method for preventing the spread of C. difficile, as it effectively removes the spores from hands. Other options, such as using alcohol hand rubs or avoiding contact, do not provide the same level of protection, making them inadequate for controlling this infection. Proper hand hygiene is essential in healthcare settings to protect both patients and staff.
