Certified Wound Ostomy Nurse (CWON) Practice Test

What is a common limitation associated with removable cast walkers?

1. They are very lightweight and easy to wear

2. They can accommodate foot deformities

3. They may not provide adequate support for wounds

4. They are inexpensive and insurance-covered

The correct answer is: They may not provide adequate support for wounds

Removable cast walkers are designed primarily to facilitate mobility while providing a level of protection and support to the foot or ankle following an injury or surgery. However, a common limitation of these devices is that they may not provide adequate support for wounds, particularly in cases where there is significant tissue loss or the wound is located in an area that requires specialized offloading. While removable cast walkers can be beneficial for certain conditions, they might not offer the necessary stability and pressure redistribution needed for optimal healing in individuals with complex wounds. For example, patients with ulcers or severe deformities may require specially designed footwear or orthotic interventions that provide customized pressure relief to prevent further complications. The other options highlight features that, while beneficial, do not reflect limitations. They mention the lightweight nature, ability to accommodate foot deformities, and cost-effectiveness of removable cast walkers, which are generally seen as advantages rather than limitations.
