A nurse is teaching a 68-year-old client how to properly use a walker. Which instruction should the nurse include to ensure the client's safety?
1Place the walker as far forward as possible with each step to maximize stride length
2Lean forward on the walker for support when walking to reduce weight on the legs
3Move the walker and both feet simultaneously to maintain balance
4Keep the walker close to the body and step into the walker frame✓ 정답
해설
Keeping the walker close to the body and stepping into the frame provides stability and prevents falls. Leaning forward or moving simultaneously can cause imbalance, while placing it far forward reduces control.
Core Nursing Explanation
This question tests the fundamental safety principles for using a standard walker, a common assistive device in gerontological and rehabilitation nursing. The core concept is stability through proper body mechanics and device positioning. A walker provides a stable base of support, but its effectiveness and safety depend entirely on correct technique.
Key Concept Analysis
The primary goal when using a walker is to prevent falls and promote safe, independent mobility. The correct technique involves a Key Point!three-point gait pattern: 1) Lift and place the walker a short, comfortable distance ahead, 2) Step forward with the weaker or affected leg into the center of the walker frame, and 3) Step forward with the stronger leg. Keeping the walker close to the body maintains the center of gravity within the base of support, maximizing stability.
Answer Rationale
Option ④, "Keep the walker close to the body and step into the walker frame," is correct because it embodies the essential safety principles.
- Close to the body: This ensures the client is not overreaching, which can cause a forward lean and loss of balance. It allows the arms and upper body to effectively control the device.
- Step into the frame: This describes the correct gait sequence where the client moves the affected or weaker leg into the space between the rear legs of the walker. This provides support during the weight-bearing phase of that leg's step.
Distractor AnalysisWatch out for confusion! Each incorrect option describes a common but dangerous error.
- Option ①: Placing the walker "as far forward as possible" forces the client to overextend, destabilizing their posture and increasing the risk of a forward fall.
- Option ②: "Lean forward on the walker" is a critical error. It puts excessive weight on the front bars, which can cause the walker to tip forward. The client's weight should be borne through the legs and feet, with the walker primarily for balance.
- Option ③: Moving the walker and both feet "simultaneously" is essentially hopping, which is highly unstable and offers no support during movement. The walker must be stationary and planted firmly when the client is stepping.
Related Concepts
This instruction is part of broader mobility aid education. Nurses must also assess the walker for proper fit (elbows should be flexed at 15-30 degrees when hands are on the grips), ensure rubber tips are intact, and teach the client to look forward, not down at their feet. Education on navigating doors, carpets, and stairs is also crucial.
Concept SummaryGoal: Safe, independent ambulation with a stable base of support. Core Principle: Maintain center of gravity within the walker's base. Walker close, step inside. Gait Pattern: Standard three-point gait (walker → weaker leg → stronger leg). Key Safety Checks: Proper fit, intact rubber tips, level surface awareness.
Side-by-Side Comparison!
Device
Primary Use & Stability
Key Gait Instruction
Walker (Standard)
Maximum stability. For significant weakness, imbalance, or non-weight-bearing status.
"Lift, place, step in. Keep it close." Three-point gait.
Crutches
Moderate-high stability. For leg injury (fracture, sprain). Requires good upper body strength.
Body weight on hands, not armpits. Various gaits (2-point, 3-point, swing-through).
Cane (Single-point)
Minimal stability. For mild balance issues or unilateral weakness.
Hold in hand opposite the affected leg. Move cane and affected leg together.
Anatomy, Physiology & Pharmacology Points
- Body Mechanics: A wide base of support (the walker) lowers the center of gravity, increasing stability per the principles of physics.
- Musculoskeletal: Correct use engages core and upper body muscles for support without straining the shoulders or back.
- Geriatric Considerations: Older adults often have decreased muscle strength, proprioception, and reaction time, making precise technique even more critical for fall prevention.
Memory Tips
- Acronym: W.I.S.E. Walk Walker close to body. Inspect tips and height before use. Step into the frame with weak leg first. Eyes up (look ahead, not down).
- Visual Cue: Imagine the walker as a moving "door frame." You step through the doorway, you don't chase after it or hang on the doorjamb.
High-Frequency NCLEX Topics
Safe use of assistive devices is a Core topic. The NCLEX-RN often tests:
1. Selecting the appropriate device based on client need (e.g., cane for mild imbalance vs. walker for post-hip fracture).
2. Correct patient education points (as in this question).
3. Safety assessments (checking rubber tips, proper height adjustment).
4. Prioritizing mobility interventions in a care plan.
Watch Out for Question Variations!
- Instead of teaching, the question may ask: "The nurse observes a client using a walker. Which action by the client requires immediate intervention?" (Answer: Leaning heavily on the front bars).
- The scenario could involve a specific post-operative client (e.g., total knee replacement) where weight-bearing status (toe-touch vs. partial) modifies the gait instruction.
- It may be combined with home safety: "Which finding in the home of a client who uses a walker poses the greatest risk?" (Answer: Throw rugs on hardwood floors).
Nursing Clinical Practice GuideClinical Scenario: You are caring for Mr. Johnson, a 68-year-old man who is 2 days post-op from a right total hip replacement (THA). He is cleared for ambulation with weight-bearing as tolerated (WBAT) on the right leg. He has been provided with a standard walker. His room has a vinyl floor, and there is a small bathroom rug just outside the bathroom door.
Nursing Intervention Strategy
1. Assessment: Before ambulation, assess Mr. Johnson's pain level, dizziness, and strength. Check the walker for proper height (elbows slightly bent) and ensure all four rubber tips are secure and not worn.
2. Education & Demonstration:
- Use the "teach-back" method. First, demonstrate the correct technique: "Mr. Johnson, I'm going to show you how to walk safely with this. I lift the walker and place it about one step ahead, keeping it close to me. Then, I step forward with my right (operative) leg, right into the middle of the walker. Finally, I bring my left leg forward to meet it."
- Have him practice sitting at the bedside first, practicing standing up by pushing up from the chair arms, not by pulling on the walker.
3. Assisted Ambulation: Stand on his affected (right) side. Apply a gait belt. Guide him through the sequence: "Lift. Place. Step with your right. Now step with your left." Cue him to keep his head up.
4. Environmental Safety: Point out the bathroom rug. Key Point! Instruct him to either remove the rug or ensure the walker's legs are completely on the rug or completely off it to prevent catching a tip. Teach him to navigate the bathroom door by approaching it straight on.
Patient Safety and Precautions
1Contraindication:Do not allow a client to use a walker if they cannot follow simple commands or have severe upper extremity weakness that prevents them from lifting it.
2Critical Monitoring:Watch for signs of fatigue, instability, or increased pain during ambulation. Never leave a novice user unattended.
3Precautions for Specific Surgeries:For THA clients, reinforce hip precautions (no flexion >90 degrees, no adduction, no internal rotation) even while using the walker. They must not pivot on the operative leg.
Nursing Procedure & Medication FlowWalker Fitting & Ambulation Procedure:
1. Adjust height so the handgrips are at wrist level when the client stands with arms relaxed.
2. Apply a gait belt.
3. Position yourself to the side and slightly behind the client, on the side of the weaker extremity.
4. Instruct the sequence: "Lift walker → Place it firmly → Step in with weak leg → Step forward with strong leg."
5. Continually assess posture, balance, and fatigue.
6. To sit: Have the client back up until the backs of their legs touch the chair, reach for the chair arms, and lower themselves slowly. The walker should not be used to pull up to a standing position.
A Word from Your Senior Nurse
"Teaching mobility is one of the most hands-on and rewarding parts of our job. Seeing a patient regain independence is powerful. Remember, the walker is a tool for their safety and confidence. Your calm, clear instructions and vigilant spotting make all the difference. In clinicals and on the NCLEX, always think: 'What creates the widest, most stable base? What keeps their center of gravity centered?' That mindset will guide you to the right answer and, more importantly, keep your patients upright and safe."
Walker — A mobility aid consisting of a metal frame with four points of contact with the floor, providing maximum stability for clients with significant weakness, balance deficits, or during post-operative recovery.
Three-Point Gait — A gait pattern used with walkers or crutches where the device and the affected leg are moved forward separately from the unaffected leg. Sequence: Device → Affected leg → Unaffected leg.
Gait Belt — A sturdy belt worn around a client's waist used by healthcare personnel to safely support and assist during transfers and ambulation, providing a secure handhold.
Base of Support — The area beneath a person or object that includes every point of contact with the supporting surface. A wider base of support (like a walker provides) increases stability.
Weight-Bearing as Tolerated — A medical order for ambulation that allows the client to put as much weight on an affected limb as comfort allows, progressing from partial to full weight-bearing.
