Determining prognosis involves a combination of clinical assessment, diagnostic tests, and sometimes predictive models. Nurses play a key role in this process by: 1. Clinical Observation: Monitoring vital signs, symptoms, and response to treatments. 2. Patient History: Gathering comprehensive patient histories to understand the baseline health status. 3. Diagnostic Results: Interpreting lab results, imaging studies, and other diagnostic tests. 4. Multidisciplinary Collaboration: Working closely with physicians, specialists, and other healthcare professionals to gather a holistic view of the patientâs condition.
