During a regular home health visit to an elderly client, the nurse observes that the client has feelings of hopelessness and despair. The client says, "I'm old, and my life has no purpose anymore. But promise me you won't tell anyone." How should the nurse respond?

A. The nurse must not promise to keep information about hopelessness or potential suicidal thoughts secret because safety concerns override confidentiality; the nurse should explain this and immediately assess for suicidal ideation and take appropriate protective actions. B. Promising not to tell anyone maintains secrecy and prevents the nurse from ensuring the client's safety. C. Asking “What can we do to help you feel better?” is therapeutic but skips the necessary clarification about confidentiality and an immediate suicide risk assessment. D. Changing the subject to “cheer you up” minimizes the client's feelings and is nontherapeutic.
