What symptom should a nurse closely monitor in a patient diagnosed with depression?

Monitoring extreme sadness in a patient diagnosed with depression is crucial because it is a core symptom of the disorder. Depression often manifests through pervasive feelings of sadness, hopelessness, and despair, which can profoundly affect the individual's ability to function in daily life. A nurse's focus on this symptom is important not only for assessing the severity of the depression but also for determining the appropriate treatment interventions and evaluating the patient's response to therapy.

By closely observing this symptom, the nurse can gauge the patient's mental state and safety, as extreme sadness can sometimes lead to suicidal thoughts or behaviors, necessitating immediate intervention. Observing and documenting these changes can help healthcare providers adjust treatment plans effectively whether that involves medication management, psychotherapy, or additional support services.
