Question

Quizplus · Accepted Answer

The CDC's recommendations for adequate hand hygiene are as follows:
Artificial nails should not be worn; studies show that even after careful hand hygiene, healthcare workers with artificial nails have more pathogenic microbes under their nails and on their fingertips than workers with natural nails. Artificial nails also cause nail changes that contribute to the transmission of microbes.
Visibly soiled hands should be washed for a minimum of 15 seconds with antimicrobial soap and warm, running water.
Alcohol hand rubs should be used before and after contact with each patient, and also after removing gloves, to prevent cross-contamination among patients and healthcare workers.
To use an alcohol hand rub properly, apply the label-recommended amount to the palm of one hand and rub the hands together, covering all surfaces until the hands are dry.
Natural nail tips should be no longer than 1/4 inch to prevent microbial growth in the nail bed.
