Wisconsin CNA State Exam Vocabulary Practice

What are bacteria?

1. Friends of the body

2. Harmful rays from the sun

3. Muscle-building cells

4. Disease-causing germs

The correct answer is: Disease-causing germs

Bacteria are classified as disease-causing germs, which makes this choice accurate. They are single-celled microorganisms that can be found in various environments and can have both beneficial and harmful effects on human health. When we refer to bacteria as "disease-causing germs," we acknowledge that certain types can lead to infections and illnesses, which is crucial knowledge for a CNA when providing care. Understanding the role of harmful bacteria is essential for implementing proper hygiene practices and infection control measures to safeguard patient health. The other options do not accurately reflect the nature of bacteria; for example, bacteria are neither friends of the body in a general sense nor directly related to muscle-building cells or harmful rays from the sun.
