Final answer:
The most significant action a CNA can take to prevent the spread of infection is proper handwashing, which serves as a fundamental defense against transmitting infectious microbes found on various surfaces.
Step-by-step explanation:
The most significant action a Certified Nursing Assistant (CNA) can take to prevent the spread of infection is proper handwashing. This is not just a routine task but a critical step in ensuring patient safety and maintaining a hygienic environment. With microbes present on numerous surfaces like doorknobs and medical equipment, hand hygiene becomes a primary defense against infections.
Handwashing involves several essential steps: wetting hands with water, applying soap, scrubbing all parts of the hands for at least 20 seconds, rinsing thoroughly under running water, and finally drying hands with a clean towel or air dryer. CNAs should perform handwashing before and after patient contact, after removal of gloves, and after contact with any potentially infectious materials.
In the context of healthcare, frequent and meticulous handwashing helps protect both healthcare workers and patients from various infections, including respiratory illnesses like flu, coronavirus disease, and the common cold. As such, every healthcare setting should emphasize the importance of this practice to all staff members.
