Clinical meaning
The nursing process (assessment, diagnosis, planning, implementation, evaluation) is a systematic, evidence-based framework that guides clinical decision-making at the nurse level. Clinical judgment requires integrating pathophysiological knowledge with patient-specific data: recognizing that tachycardia may represent compensatory catecholamine release in early hypovolemic shock before blood pressure drops, that rising respiratory rate is often the earliest vital sign change in clinical deterioration, and that new-onset confusion in an elderly patient may signal hypoxia, sepsis, medication toxicity, or electrolyte imbalance rather than simple delirium. The nurse applies prioritization frameworks (ABCs, Maslow's hierarchy) to determine which patient needs are most urgent, delegates tasks using the Five Rights of Delegation while retaining accountability for outcomes, and communicates clinical concerns using SBAR to ensure critical information is transmitted accurately during handoffs and escalations.
