A client who recently lost their spouse exhibits signs of withdrawal, expresses feelings of hopelessness, and reports difficulty sleeping and eating. Which stage of grief is the client most likely experiencing, and what is the nurse's most appropriate intervention?

Rationale: A. Anger may involve blaming others or expressing frustration, not withdrawal and hopelessness. B. Denial typically involves difficulty believing the loss occurred, not the low mood and physiological symptoms described. C. Acceptance involves beginning to plan for the future, which is inconsistent with the client's current hopelessness and withdrawal. D. The client's symptoms are consistent with the depression stage of grief. The appropriate intervention is to offer empathetic support and assess for suicidal ideation or risk of self-harm, ensuring safety while providing emotional care.
