DANB's Certified Orthodontic Assisting - Test Reviews Sample Questions

It’s a busy day and you are working on a patient, and called to another room to examine another patient. What is the MOST effective way to prevent cross contamination and transmission of disease?

Correct Answer:
hand hygiene.


when working in a healthcare setting, especially on a busy day involving multiple patients, the question of how to effectively prevent cross-contamination and transmission of diseases is crucial. the options provided include changing your gown, hand hygiene, changing your protective eyewear, and putting on a new face mask. among these, the most effective method recommended is hand hygiene.

hand hygiene stands out as the primary and most critical preventive measure in healthcare settings. this is because hands are the primary mode of germ transmission between patients and healthcare providers. proper hand hygiene involves thoroughly washing hands with soap and water or using an alcohol-based hand sanitizer before and after contact with each patient, after contact with potentially contaminated surfaces or equipment, and before performing any aseptic tasks.

while changing gowns, protective eyewear, and face masks are important and contribute to reducing the risk of disease transmission, these measures are secondary compared to hand hygiene. gowns, eyewear, and masks primarily serve as barriers to protect the skin and mucous membranes from contact with infectious agents. however, they do not replace the need for clean hands, which come into direct contact with patients.

moreover, the effectiveness of other protective barriers like gowns, masks, and eyewear depends largely on their proper use and disposal. for example, a gown must be changed if visibly soiled or penetrated by fluids, and masks should be replaced if they become damp or damaged. however, since these items do not come into direct contact with the patient as frequently as hands, they are not the primary mode of transmission.

in conclusion, while all the mentioned preventive measures are important in their own right, hand hygiene remains the most effective way to prevent cross-contamination and the transmission of diseases in a healthcare setting. ensuring that hand hygiene is diligently practiced can significantly reduce the spread of pathogens and protect both healthcare workers and patients from infections.
