A nurse is teaching a newly licensed nurse about the difference between a plaster cast and a synthetic cast. Which of the following information should the nurse include in the teaching?
Drying time is prolonged with a synthetic cast.
A synthetic cast is weighs less.
A plaster cast requires expensive equipment for application.
A synthetic case immobilizes bone fractures more effectively.
The Correct Answer is B
A. This statement is incorrect. Drying time is actually shorter with a synthetic cast compared to a plaster cast. Synthetic casts use a chemical reaction for hardening, which typically sets faster than the drying process of plaster.
B. Correct. A synthetic cast is generally lighter in weight compared to a plaster cast. This can be more comfortable for the patient and may provide better mobility.
C. This statement is incorrect. Plaster casts do not necessarily require expensive equipment for application. Both types of casts require appropriate materials and training for application, but cost can vary based on factors like the type of material and the specific clinical setting.
D. This statement is incorrect. Both plaster and synthetic casts are effective for immobilizing bone fractures when applied correctly. The choice between the two often depends on factors such as the type of fracture, patient comfort, and clinician preference.

Correct Answer is C
Explanation
A. Remove the elastic bandage and re-wrap the stump once per day: This is not recommended. The elastic bandage provides support and helps reduce swelling. It should only be removed and re-wrapped as directed by the healthcare provider.
B. Secure the elastic bandage to the lowest joint: The bandage should be secure, but it should not be tied too tightly or secured directly over a joint. This could restrict blood flow and cause discomfort.
C. Wrap the stump with an elastic bandage in a figure-eight configuration: This is the correct action. A figure-eight configuration helps distribute pressure evenly, providing support and reducing the risk of edema and complications.
D. Perform passive range-of-motion exercises once daily: Range-of-motion exercises are important, but they should be performed within the parameters set by the healthcare provider. They should not be performed only once daily, and it's essential to avoid overexertion or straining the residual limb.
