When should a CNA wash their hands?

Washing hands is a critical aspect of infection control in healthcare settings, and it helps prevent the spread of pathogens. The correct answer emphasizes the necessity of washing hands before and after patient contact, after using the restroom, and after handling any contaminated materials. This comprehensive practice ensures that any potential contaminants are removed prior to interacting with patients, thereby safeguarding both the health of the patients and the healthcare worker's own health.

Frequent handwashing at these key times is essential because it significantly reduces the risk of healthcare-associated infections. For instance, by washing hands before patient contact, the CNA minimizes the risk of transmitting pathogens from their own hands to patients. Similarly, washing hands after patient contact, as well as after using the restroom or handling contaminated items, helps to eliminate any pathogens that may have been acquired during those interactions.

While washing hands at the beginning of each shift and before eating and after exercising is also important for personal hygiene, these practices do not directly address the specific protocols required in a healthcare setting to protect patients and reduce infection risk following interactions within that environment. The only practice that captures all necessary instances of hand hygiene relevant to patient care is the chosen answer.
