The client is now cleared for ambulation. What is the most important nursing intervention when assisting this client to ambulate for the first time? ## 보기 1. Encourage the client to walk as far as possible to regain strength quickly 2. Have the client sit on the edge of the bed for 2-3 minutes before standing 3. Apply a gait belt and provide support on the client's weaker side 4. Check the client's blood pressure and pulse before, during, and after ambulation **✔ 정답** **정답: 4** ## 해설 Monitoring vital signs (blood pressure and pulse) before, during, and after ambulation is most important to assess for orthostatic hypotension and cardiovascular changes after prolonged bed rest. Other interventions (sitting before standing, using a gait belt) are safety measures but do not provide objective data for immediate risk assessment. ## 심화 해설 Understanding the Rationale: Why Vital Signs Are the Priority When a client transitions from prolonged bed rest to ambulation, the body undergoes significant physiological stress. The most critical risk is orthostatic hypotension, a sudden drop in blood pressure upon standing. After 5 days of immobility, the autonomic nervous system's baroreceptor response is blunted, and blood vessels in the legs may not constrict efficiently to return blood to the heart. This can lead to dizziness, syncope, or a fall. Therefore, assessing the client's hemodynamic stability by checking blood pressure and pulse before, during, and after the activity is the foundational safety intervention. This establishes a baseline, detects intolerance early, and confirms recovery post-activity. Analyzing the Incorrect Options - Option 1: Encouraging the client to walk as far as possible is unsafe. The concept of early mobilisation after abdominal surgery, as explored in the concept analysis, is defined by a phased, progressive approach, not maximal exertion [1]. Pushing a deconditioned client to the point of fatigue increases the risk of falls, wound dehiscence, and cardiovascular complications. - Option 2: Having the client sit on the edge of the bed, or "dangling," is a correct and necessary step in the progression to ambulation. However, it is not the most important intervention. Dangling is a preparatory action, but without first knowing the client's baseline vital signs and orthostatic response, you cannot safely proceed even to this step. - Option 3: Applying a gait belt and providing support is a crucial safety measure during the actual ambulation. Yet, this is a secondary intervention. The primary assessment of physiological tolerance through vital sign measurement must come first to determine if it is even safe to stand and use the gait belt. Connecting to Clinical Practice and ERAS Protocols This nursing action is a cornerstone of the Enhanced Recovery After Surgery (ERAS) concept. Research on nursing under ERAS protocols demonstrates that structured, safety-focused interventions directly impact the time to first ambulation and reduce postoperative complications . A core component of this structured approach is the continuous monitoring of physiological parameters to guide the progression of mobility. The goal is not just early ambulation, but safe early ambulation. Similarly, in complex surgical populations, such as children after cerebral AVM surgery, early ambulation is defined as a phased, progressive mobility protocol initiated within a specific timeframe, where ongoing assessment of tolerance is paramount . The nurse's role is to use vital sign data to titrate the activity, ensuring the client's response remains within a safe clinical range.References (research sources) - [1]Early mobilisation after abdominal surgery: a concept analysis.Research articleSchandl A, Siesage K, Kroksmark AK, Gruber-De Sousa E, Lilliecrona J, Olsén MF. (2026) · DOI: 10.1136/bmjopen-2025-107830 ## 임상 시나리오 Clinical Practice Guide: First Ambulation After Prolonged Bed Rest Key Assessment - Obtain baseline lying, sitting, and standing blood pressure and pulse to screen for orthostatic hypotension. - Define orthostatic hypotension as a drop in systolic BP of 20 mmHg or diastolic BP of 10 mmHg within 3 minutes of standing. - Assess for symptoms of intolerance: dizziness, lightheadedness, blurred vision, nausea, or weakness. Progressive Mobilization Sequence - Position client supine and measure vital signs. - Elevate head of bed to semi-Fowler's; reassess for symptoms. - Dangle legs over edge of bed for 2-3 minutes; recheck vitals if symptomatic. - Assist to standing position with gait belt applied; measure orthostatic vital signs immediately. - Ambulate short distances with close supervision; monitor vitals during and after activity. Safety Interventions - Apply a gait belt around the client's waist and stand on the weaker side. - Ensure a clear path and use non-slip footwear. - Stop activity immediately if systolic BP drops below baseline, pulse rises excessively, or client reports symptoms. - Document tolerance, vital sign trends, and distance achieved. Prioritizing hemodynamic assessment before mobilization prevents falls and syncope in postoperative clients. ## 핵심 개념 - **Orthostatic Hypotension** — A sudden drop in blood pressure when moving from lying to sitting or standing, causing dizziness or syncope due to blunted baroreceptor response and venous pooling. - **Baroreceptor Response** — The autonomic nervous system mechanism that regulates blood pressure; prolonged bed rest blunts this response, impairing vasoconstriction. - **Dangling** — The nursing intervention of having a client sit on the edge of the bed with legs dependent to allow gradual adjustment to an upright posture before standing. - **Syncope** — A temporary loss of consciousness often caused by a sudden drop in blood pressure leading to inadequate cerebral perfusion. ## 같은 주제 문제 - [A nurse is assessing a patient's mobility status.
