The nursing diagnosis identifies health problems that are preventable or treatable by nursing interventions. This process has several goals—determining actual or potential health problems, ruling out factors contributing to or causing issues, and identifying resources to prevent or resolve the problems. The nursing diagnosis focuses on evidence-based interventions. It includes anticipating illness and complications, controlling or reducing risk, and promoting optimum health. For example, the nurse witnesses increased body weight and ankle swelling in a patient with cardiac failure. Accordingly, they restrict fluid and salt intake to manage risk and prevent complications such as cardiac overload. The nurse then monitors the health response by assessment and evaluation. A timeline assessment analyzes the quality of life over time following nursing management. As a result, the patient obtains a timely response and appropriate treatment. The nursing diagnosis, therefore, identifies and prioritizes potential actions to alleviate sickness, and the nursing intervention and its outcome work to resolve the patient's problem.
