Question: 1 / 400
When is a plaster bandage roll considered ready for application?
When it is warm to the touch
When it is dry to the touch
When air bubbles cease to appear
A plaster bandage roll is considered ready for application when air bubbles cease to appear during the mixing process. This indicates that the plaster has been adequately wetted and activated, leading to a consistent mixture that will adhere properly during application. The formation of air bubbles suggests that there are still dry areas that need to be saturated with water; once these bubbles stop appearing, you can be confident that the plaster is fully prepared to bond to the surface it is being applied to, providing effective support and stabilization.
The reaction of gypsum plaster during mixing involves a chemical process where water is absorbed, and once the mixture reaches a certain level of hydration without air pockets, it becomes ready for use. This preparation is crucial to ensure the strength and integrity of the final cast.
