A nurse is teaching a client how to use crutches safely. Which instruction should the nurse emphasize to prevent falls and injury?
1Place the crutches as far forward as possible with each step to cover more ground quickly
2Keep the crutches close to the body and maintain three points of contact at all times✓ 정답
3Lean heavily on the crutches to reduce weight bearing on the affected leg
4Move both crutches simultaneously with the unaffected leg for faster mobility
해설
Maintaining three points of contact (e.g., two crutches and one foot) ensures stability and prevents falls during crutch walking. Other options promote unsafe practices like overreaching, leaning heavily, or moving crutches simultaneously, which increase fall risk.
Core Nursing ExplanationKey Concept Analysis: This question assesses the fundamental safety principle for Crutch walking. The core concept is maintaining a stable, wide base of support to prevent falls. The safest gait patterns, such as the three-point gait, are designed to keep the patient's center of gravity within this base.
Answer Rationale: Key Point! The instruction to "Keep the crutches close to the body and maintain three points of contact at all times" is the cornerstone of safe crutch use. Keeping crutches close prevents the center of gravity from shifting too far forward or laterally, which can cause a loss of balance. "Three points of contact" means that at least three of the four points (two crutch tips and two feet) are always in contact with the ground, ensuring maximum stability. This principle is critical for preventing falls and injury.
Distractor Analysis: Watch out for confusion! Option ① is incorrect because placing crutches too far forward creates an unstable, overreached position, moving the center of gravity outside the base of support and significantly increasing fall risk.
Option ③ is incorrect. While crutches are for support, leaning heavily on the axillary (armpit) bars can cause Radial nerve palsy or "crutch palsy." Weight should be borne on the hands via the handgrips, not the axillae.
Option ④ is incorrect. Moving both crutches simultaneously with the unaffected leg describes a swing-through gait, which is an advanced, less stable pattern typically used by individuals with paraplegia or excellent upper body strength. It is not the standard, safe method taught to most patients for initial ambulation and increases the risk of losing balance.
Related Concepts: Safe crutch walking involves more than just moving; it includes proper crutch fitting (2-3 finger-widths between axilla and pad), correct handgrip positioning (elbows slightly flexed at 20-30 degrees), and choosing the appropriate gait (e.g., three-point, two-point, four-point) based on the patient's weight-bearing status and coordination.
Concept Summary: Crutch Safety = Maintain three points of contact + Keep crutches close to body + Bear weight on hands, not axillae + Use prescribed gait pattern.
Side-by-Side Comparison!:
Gait Pattern
Sequence (Crutch = C, Affected Leg = A, Unaffected Leg = U)
Indication / Stability
Three-Point Gait
Move both crutches and the affected leg forward together, then step through with the unaffected leg.
Non-weight-bearing or partial weight-bearing on one leg. Very stable.
Four-Point Gait
Right crutch → Left foot → Left crutch → Right foot.
Partial weight-bearing on both legs. Maximum stability but slow.
Two-Point Gait
Right crutch and left foot together, then left crutch and right foot together.
Partial weight-bearing on both legs. Faster than four-point, requires more coordination.
Swing-Through Gait (Advanced)
Move both crutches forward, then swing both legs past the crutches.
Used by individuals with paralysis (e.g., paraplegia). Requires significant upper body strength and balance.
Anatomy, Physiology & Pharmacology Points: The primary anatomical concern is protecting the Brachial plexus and Radial nerve, which run through the axilla. Improper crutch use (leaning on axillary bars) compresses these nerves, leading to temporary or permanent damage, manifesting as wrist drop (inability to extend the wrist) and numbness.
Memory Tips: Remember the rule of "3 C's for Crutch Safety": Close to body, Contact (three points), Correct gait. To avoid nerve injury: "Hands hold, axillae are off-limits!"
High-Frequency NCLEX Topics: Safe patient mobility and use of assistive devices (canes, walkers, crutches) is a Core topic. NCLEX often tests on selecting the correct assistive device, teaching safe techniques, and identifying unsafe practices in a scenario.
Watch Out for Question Variations!: The same concept can be tested by: 1) Asking for the priority instruction for a patient using crutches for the first time (safety first!). 2) Showing a picture of improper crutch use and asking what the nurse should correct. 3) Asking which patient statement indicates understanding of safe crutch walking.
Nursing Clinical Practice GuideClinical Scenario: You are caring for Mr. Johnson, a 65-year-old who underwent a total knee replacement yesterday. The physical therapist has just fitted him with axillary crutches and instructed him in a three-point, toe-touch weight-bearing gait. You are now reinforcing this teaching at the bedside.
Nursing Intervention Strategy:
1AssessmentBefore teaching, assess the patient's upper body strength, balance, coordination, and cognitive status. Check the crutch fit: There should be a 2-3 finger width gap between the axillary pad and his armpit when he stands upright. His elbows should be flexed 20-30 degrees when his hands are on the handgrips.
2Teaching & Implementation- Demonstrate the three-point gait: "Move both crutches and your surgical leg forward together. Now, step through with your good leg, placing it slightly ahead of the crutch tips."
- Emphasize safety: "Always look ahead, not down at your feet. Keep the crutches close to your sides. Remember, at least three points (two crutches and one foot) should be touching the floor before you move."
- Supervise return demonstration in a clear, unobstructed area.
3Patient EducationTeach him to inspect the crutch tips for wear, ensure all bolts are tight, and to wear sturdy, non-slip shoes. Warn him never to lean on his armpits and to report any numbness or tingling in his hands or arms immediately.
Patient Safety and Precautions: The primary safety hazard is a fall. Ensure the environment is safe: clear floor of clutter, secure loose rugs, ensure good lighting. Never allow a patient to use crutches on a wet or slippery surface. Monitor for signs of nerve compression (numbness, tingling, weakness in hands/arms).
Nursing Procedure & Medication Flow: While crutch walking isn't a medication, think of it procedurally: 1) Verify the order (weight-bearing status from the surgeon). 2) Gather equipment (properly fitted crutches, gait belt). 3) Perform patient assessment. 4) Educate and demonstrate. 5) Supervise and evaluate return demonstration. 6) Document the teaching and the patient's response/ability.
A Word from Your Senior Nurse: "Teaching mobility is one of the most practical and empowering things we do as nurses. Seeing a patient regain independence is incredibly rewarding. But safety is non-negotiable. In clinicals, never skip the 'return demonstration'—it's where you catch misunderstandings that could lead to a fall. For the NCLEX, always prioritize safety and stability over speed. If an answer choice suggests a faster but riskier method, it's almost always wrong. Think like a guardian: your goal is to get your patient moving safely, not quickly."
Three-Point Contact — A safety principle in crutch walking where at least three points (two crutch tips and one foot, or one crutch tip and two feet) maintain contact with the ground to ensure stability.
Axillary Crutches — The most common type of crutches, with a top piece that fits under the armpit (axilla). Proper use requires bearing weight on the hands, not the axillae, to prevent nerve damage.
Radial Nerve Palsy — Nerve injury often caused by improper crutch use (pressure in the axilla), leading to weakness in wrist and finger extension, sometimes called "wrist drop" or "crutch palsy."
Three-Point Gait — A crutch-walking pattern where both crutches and the affected (non-weight-bearing or partial weight-bearing) leg move forward together, followed by the unaffected leg.
Weight-Bearing Status — A physician's order specifying how much weight a patient can place on an affected extremity (e.g., Non-weight-bearing (NWB), Toe-touch weight-bearing (TTWB), Partial weight-bearing (PWB), Full weight-bearing (FWB)). This dictates the gait pattern taught.
