Final answer:
Wearing artificial nails as a CNA is a bad idea because they can harbor bacteria and make it difficult to properly clean hands. Artificial nails can also contain toxic chemicals that can pose health risks.
Step-by-step explanation:
It is a bad idea for a CNA (Certified Nursing Assistant) to wear artificial nails to work because they can harbor harmful bacteria and make it difficult to properly clean and sanitize hands. Artificial nails can easily trap dirt, pathogens, and healthcare-associated infections (HAIs) causing microorganisms, which can then be spread to patients or other healthcare workers. In addition, some nail products contain toxic chemicals, such as formaldehyde and toluene, which can pose health risks when prolonged exposure occurs.
