Final answer:
The nurse's statement that best demonstrates the 'offering self' communication technique is expressing a willingness to be present with the patient without pressuring them to talk, which can establish trust and comfort.
Step-by-step explanation:
The communication technique of 'offering self' is intended to establish rapport and trust with a patient by providing your presence as a means of support, rather than directly seeking information or pressuring the patient to speak.
Considering the options provided, the comment that demonstrates this technique best is: "I'd like to sit with you for a while to help you get comfortable talking to me." This statement shows that the nurse is willing to be present and available for the patient without any immediate expectations or pressure, which is in line with providing comfort and establishing a therapeutic relationship.
