A nurse is teaching an elderly client with osteoporosis and a recent left hip replacement how to use crutches for partial weight-bearing. Which instruction should the nurse provide to ensure safe crutch walking?
The nurse is demonstrating proper crutch walking technique to a client who will be non-weight bearing on the left leg.
1Place the crutch tips 6 inches in front and 6 inches to the side of each foot✓ 정답
2Lean forward on the crutches when walking to maintain balance
3Place all weight on the axilla when using the crutches
4Move the injured leg and both crutches simultaneously in a three-point gait
해설
Proper crutch positioning (6 inches in front and to the side of each foot) creates a stable base of support to prevent falls. Other options involve unsafe techniques like leaning forward, placing weight on axillae, or moving crutches and injured leg simultaneously, which can cause instability or nerve damage.
Core Nursing ExplanationKey Concept Analysis: This question assesses safe crutch walking technique for a patient with a hip replacement who is partial weight-bearing. The core principle is establishing a stable base of support to prevent falls and avoid injury to the axillary area. For any ambulatory aid, the tips must be positioned to create a wide, stable triangle with the patient's body.
Answer Rationale: Key Point! Option ① is correct because placing crutch tips 6 inches in front and 6 inches to the side of each foot creates the optimal, wide-based tripod stance. This position maximizes stability before initiating movement, which is crucial for an elderly client with osteoporosis (increased fracture risk) and a recent surgery.
Distractor Analysis:
Watch out for confusion! Option ② is incorrect. Leaning forward on the crutches shifts the center of gravity too far forward, increasing the risk of a forward fall. Proper posture involves standing erect with elbows slightly bent (20-30 degrees).
Option ③ is a critical error. Placing weight on the axillae can compress the brachial plexus and axillary blood vessels, leading to crutch palsy (nerve damage) or circulatory impairment. Weight should be borne through the hands on the handgrips.
Option ④ describes an incorrect sequence for a three-point gait. In a standard three-point gait for non-weight-bearing, the patient moves both crutches and the injured leg forward together, then swings the unaffected leg through. The option says "move the injured leg and both crutches simultaneously," which is technically the correct action for a three-point gait, but the question stem specifies the client is for partial weight-bearing, not non-weight-bearing. Therefore, a two-point or four-point gait (allowing for partial weight on the injured leg) is more appropriate. This makes the instruction incorrect for the client's prescribed weight-bearing status.
Related Concepts: Understanding different gait patterns (two-point, three-point, four-point, swing-to, swing-through) is essential and depends on the patient's weight-bearing status, strength, and coordination. Always verify the physician's order for weight-bearing (non-weight bearing, toe-touch, partial, weight-bearing as tolerated, full).

Sequence (Crutch = C, Affected Leg = A, Unaffected Leg = U)
Weight-Bearing Status
Use Case
Two-Point Gait
Move C + A together, then U.

Move both C + A together, then U.
Non-Weight-Bearing
Fracture, amputation
Four-Point Gait
Move Right C, Left A, Left C, Right A (slow, stable).
Partial Weight-Bearing
Poor balance, neurological conditions
Anatomy, Physiology & Pharmacology Points
Anatomy: The axilla contains the brachial plexus (nerves C5-T1) and the axillary artery/vein. Direct pressure can cause radial nerve palsy (wrist drop) or ischemia.
Pathophysiology: Osteoporosis decreases bone density, increasing fracture risk from even minor falls. A hip replacement requires strict adherence to weight-bearing limits to allow proper prosthetic fixation and healing.
Biomechanics: The tripod stance widens the base of support, lowering the center of gravity and significantly improving postural stability.
Memory Tips
Tripod Rule: "6 front, 6 side, for a stable ride."
Weight Bearing: "Hands hold the weight, or you'll crush the gate" (gate = brachial plexus in axilla).
Gait Patterns: Number of points = Number of things touching the ground in the initial move (Two-point: 2 points - 1 crutch + opposite foot).
High-Frequency NCLEX Topics
Crutch walking safety is a Core NCLEX topic, often tested with specific patient scenarios (elderly, post-op, neurological). Focus on: 1) Correct measurement, 2) Safe tripod position, 3) Avoiding axillary pressure, 4) Matching gait pattern to weight-bearing order.
Watch Out for Question Variations!
Instead of asking for instruction, it may ask: "The nurse observes the client leaning on the axillae. Which complication is the client at risk for?" Answer: Radial nerve injury/crutch palsy.
Scenario change: A client with a right below-knee amputation (non-weight-bearing) is learning crutches. Which gait should the nurse teach? Answer: Three-point gait.
Calculation: Determine the correct crutch length given the client's height.
Nursing Clinical Practice GuideClinical Scenario: You are caring for Mr. Johnson, a 78-year-old man with osteoporosis who underwent a left total hip arthroplasty (THA) 3 days ago. The physical therapist has cleared him for ambulation with crutches, partial weight-bearing (up to 50% of body weight) on the left leg. He is anxious about falling.
Nursing Intervention Strategy:
1. Assessment: Assess upper body strength, balance, vision, and cognitive status. Check the surgical incision site. Verify the weight-bearing order in the chart.
2. Pre-Ambulation: Ensure proper crutch fit (2-3 finger widths in axilla, correct handgrip height). Have the client practice the tripod position while seated, then standing with support.
3. Teaching & Supervision: Demonstrate the two-point gait (most suitable for partial weight-bearing): "Move your right crutch and your left (surgical) foot forward together, then step through with your right foot." Supervise multiple practice sessions in a clear hallway.
4. Environment & Safety: Clear the path of clutter and rugs. Ensure non-slip footwear. Teach how to navigate stairs ("Up with the good, down with the bad" – unaffected leg leads going up, affected leg and crutches lead going down).
5. Evaluation & Education: Evaluate for proper technique, fatigue, and pain. Educate on signs of axillary pressure (numbness, tingling in hands) and to report any fall or sudden hip pain immediately.
Patient Safety and Precautions:
Contraindication: Do not allow ambulation if the patient is dizzy, sedated, or has unstable vital signs.
Axillary Pressure: Continuously cue: "Stand tall, keep your weight on your hands."
Fall Prevention: Use a gait belt during initial training. Never leave an unsteady patient unattended.
Nursing Procedure & Medication FlowCrutch Walking Teaching Procedure:
1. Verify order and patient identity.
2. Perform pre-procedure assessment (strength, balance, pain level).
3. Adjust crutches to correct height.
4. Teach tripod position (6 inches front and side).
5. Teach prescribed gait pattern (Two-point for this case).
6. Supervise practice with a gait belt.
7. Teach sitting/standing technique from a chair (back up to chair, hold both crutches in one hand, lower self using armrests).
8. Document teaching, patient response, and competency.
A Word from Your Senior Nurse
"Mastering assistive devices is a huge step toward patient independence and confidence. In the real world, you'll often be the one reinforcing what PT taught. Watch your patient's body language – are they grimacing, holding their breath, or looking terrified? That's your cue to slow down, break the steps into smaller parts, and provide loads of encouragement. Remember, safety always trumps speed. A patient who feels secure in their technique is far less likely to fall. This hands-on skill is pure fundamentals of nursing – get it right, and you build trust that lasts."
Tripod Position — The foundational stance for crutch walking where crutch tips are placed 6 inches in front and 6 inches to the side of each foot, creating a wide, stable base of support.
Partial Weight-Bearing — A physician's order specifying that a limited amount of body weight (e.g., 25-50%) can be placed on an affected lower extremity during ambulation.
Two-Point Gait — A crutch walking pattern where the patient moves one crutch and the opposite foot simultaneously, then the other crutch and foot. Used for partial weight-bearing when the patient has adequate strength and balance.
Crutch Palsy — Radial nerve injury caused by prolonged or excessive pressure from crutch tops in the axilla, potentially leading to wrist drop and sensory loss in the hand.
Non-Weight-Bearing — A physician's order specifying that no weight whatsoever is to be placed on an affected lower extremity. Requires a three-point gait for ambulation with crutches.
