A client at the mental health center reports difficulty concentrating at work, feeling very tired during the day, and sleeping 4 to 5 hours at night. To further assess for depression, which question is most important for the nurse to ask?

Choice A reason: Asking “Do you often feel sad?” directly assesses the core symptom of depression, low mood, critical for diagnosis. The client’s reported fatigue and poor sleep suggest depression, and confirming sadness strengthens the assessment, aligning with psychiatric diagnostic criteria, making this the most important question.Choice B reason: Recent stresses may contribute to depression but are less specific than sadness, the hallmark symptom. Asking about mood directly confirms depression, while stress is a secondary factor. This question is less critical, making it incorrect for the primary depression assessment in this client.Choice C reason: Food preferences are irrelevant to depression assessment, as they do not address mood, sleep, or concentration issues. Asking about sadness targets the core depressive symptom, making this incorrect, as dietary habits do not provide diagnostic clarity for the client’s reported symptoms.Choice D reason: Sleep changes are already reported (4-5 hours), so asking about them is redundant. Confirming sadness directly assesses the primary depressive symptom, strengthening the diagnosis. This question is less essential, making it incorrect compared to probing the client’s emotional state for depression.
