• A. Conversation
• B. Communication
• C. Language
• D. Expression

Answer: (B)

Communication is the process of exchanging information with others by sending and receiving messages. It covers verbal and nonverbal exchanges—the words we use, the tone of voice, facial expressions, body language, and written notes. In a CNA role, effective communication ensures that patient needs are understood, instructions are followed, and changes in condition are reported accurately, all of which enhance safety and care quality. Conversation is just one form of communication, a back-and-forth talking moment; language is the system we use to convey meaning, and expression is how we show thoughts or feelings. But the act of actively sending and receiving messages—the full process of exchanging information—is what communication encompasses.
