Final answer:
Non-verbal patients may show pain through (A) crying and (D) body language, which serve as key indicators for healthcare professionals to assess and manage their pain.
Step-by-step explanation:
A non-verbal patient may exhibit signs of pain through various means other than spoken language. They may demonstrate pain through options such as crying and body language. Body language can include facial expressions, grimacing, protectiveness over a certain body area, or altered posture to avoid discomfort.
Crying is a direct emotional response that can indicate pain as well. Unlike verbal communication, these methods are important non-verbal cues for healthcare providers to assess and manage a patient's pain.
