Reduction of Risk Potential Q 4



Myrna, a 52-year-old client with a fractured left tibia, has a long leg cast and she is using crutches to ambulate. Nurse Joy assesses for which sign and symptom that indicates complication associated with crutch walking?
  
     A. Left leg discomfort
     B. Weak biceps brachii
     C. Triceps muscle spasm
     D. Forearm weakness
    
    

Correct Answer: D. Forearm weakness

Forearm muscle weakness is a probable sign of radial nerve injury caused by crutch pressure on the axillae. Crutch palsy is observable in axilla crutch users who rest their weight on the shoulder rest. The pressure on the brachial plexus can result in palsy to the radial and ulnar nerves. Extra padding on the shoulder rest can aid in preventing crutch palsy.

Option A: The left leg would be at rest since the fracture is at the left tibia. Crutches are vital in the short-term and long-term management of orthopedic and neurologic injuries. Through offloading body weight to the injured extremity optimal conditions are provided to allow healing of acute injuries.
Option B: All the strength spent in crutch walking falls on the forearms, not the biceps brachii. Crutches provide ambulatory support and mobility options to those with neurologic injuries or chronic orthopedic injuries enabling the individual to stay mobile and active. Crutches are a vital adjunct for those with acute and chronic injuries to maintain mobility and independence.
Option C: The triceps would not be as affected than the forearms after crutch walking The user’s strength and coordination should undergo evaluation before issuing them a set of crutches. The use of the wrong crutches can lead to injury. Most injuries are a direct result of falling.
