The nursing process consists of five phases: assessment, diagnosis, planning, implementation, and evaluation. Assessment involves collecting both subjective and objective data to establish a database about the patient's health status and needs. Diagnosis involves analyzing the data to determine nursing diagnoses. Planning involves establishing measurable goals and expected outcomes. Implementation involves carrying out the planned nursing interventions. Evaluation involves determining if the goals and outcomes were achieved in order to revise the plan if needed. The nursing process provides an organized framework to guide nursing care and develop clinical reasoning and judgment skills.
