Why might a CNA use gestures when communicating with patients?

Using gestures when communicating with patients is particularly beneficial in situations where language barriers exist. Many patients may have limited proficiency in the primary spoken language of the caregivers, or they may be hearing impaired. Gestures serve as a universal form of communication that can help convey messages more effectively than words alone in these cases. They can express emotions, directions, or information in a visual and often intuitive way, greatly enhancing understanding.

The other options, while they present different viewpoints on communication, do not align with the best practices for effective patient interaction. Substituting spoken language entirely can lead to misunderstandings, as not all nuances can be conveyed through gestures alone. Creating a more informal environment is not the primary objective of using gestures; the emphasis is on clarity and understanding. Confusing the patient is counterproductive, as effective communication should aim to promote clarity and comfort, rather than confusion.
