The nurse is sitting with a client who is crying. After a few minutes, the nurse places one hand on the client's shoulder. Which of the following best describes the purpose of the nurse's touch with this client?

A. Assessing skin temperature and circulation is a physical assessment action, not the purpose of touch in this context. B. Offering comfort and support is correct because therapeutic touch can provide reassurance and convey presence without words, especially when the client is crying. C. Expressing sympathy focuses on the nurse’s feelings rather than supporting the client. D. Extending an offer of friendship is nontherapeutic and blurs professional boundaries.
