Which term is single-celled microorganisms responsible for a range of illnesses?

• A. Barrier
• B. Anteroom
• C. Asbestos
• D. Bacteria

Answer: (D)

Bacteria are single-celled microorganisms responsible for a wide range of illnesses. They are prokaryotes, meaning they are simple cells that reproduce quickly, often by binary fission. In healthcare, bacteria can cause infections such as strep throat, urinary tract infections, pneumonia, and wound infections, and they can spread through direct contact, surfaces, or droplets. The other terms in the list aren’t living microorganisms: a barrier is a protective measure to block transmission, an anteroom is a transitional space for donning and doffing PPE, and asbestos is a mineral fiber linked to lung disease, not a microorganism.
