Final answer:
To display an open posture in patient communication, lean forward in your chair facing them, maintain eye contact, and demonstrate good posture without folding your arms.
Step-by-step explanation:
To convey an open posture while communicating with a patient, it is best to lean forward in your chair facing the patient. This body positioning indicates attentiveness and willingness to engage in the conversation. It is also important to maintain eye contact, which shows that you are engaged and alert. However, it is crucial to avoid staring or maintaining constant eye contact for too long, as this may be uncomfortable. Folding your arms should be avoided, as it can give off an impression of defensiveness. As for body language, it is helpful to sit up straight, demonstrating good posture to convey a confident and professional image.
