A. Drying time is prolonged with a synthetic cast. B. A synthetic cast is weighs less. C. A plaster cast requires expensive equipment for application. D. A synthetic case immobilizes bone fractures more effectively.

Correct Answer is B

Explanation

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.
