Assertion (A): Plaster of Paris is used by doctors for setting fractured bones.
Reason (R): When Plaster of Paris is mixed with water and applied around the fractured limbs, it sets into a hard mass.
The correct answer is option A, which states that both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion (A).
Explanation:
Plaster of Paris and its Properties:
Plaster of Paris is a white powder that is derived from gypsum. It is a versatile material that has various uses due to its unique properties. When mixed with water, it forms a paste that can be molded into any desired shape. Once it dries, it hardens into a solid mass.
Setting Fractured Bones:
Doctors use Plaster of Paris for setting fractured bones due to its setting properties. Here's how the process works:
1. Reduction of Fracture: Before applying Plaster of Paris, the fractured bone needs to be properly reduced or realigned. This is usually done by a doctor who manipulates the bone back into its correct position.
2. Application of Plaster of Paris: Once the bone is reduced, the doctor applies a layer of padding, typically cotton or soft material, around the fractured area to provide comfort and prevent direct contact between the skin and the plaster. Then, they dip strips of Plaster of Paris into water and apply them over the padding, encasing the fractured limb.
3. Setting Process: As the wet Plaster of Paris comes into contact with air, a chemical reaction called hydration occurs. During hydration, the plaster absorbs water and forms calcium sulfate dihydrate, which gives it a hard and solid structure. This setting process takes about 10-15 minutes, after which the plaster becomes firm.
4. Hardening and Immobilization: Once the plaster sets, it hardens over time, providing support and immobilization to the fractured bone. It prevents movement and helps in the healing process by keeping the bone in the correct position.
5. Duration of Plaster Cast: The duration for which the plaster cast needs to be worn depends on the severity of the fracture and the individual's healing progress. It can range from a few weeks to several months.
Explanation of Assertion and Reason:
The assertion (A) states that doctors use Plaster of Paris for setting fractured bones, which is true. The reason (R) explains the process of how Plaster of Paris sets into a hard mass when mixed with water and applied around the fractured limbs. This reason is also true and provides a correct explanation for the use of Plaster of Paris in setting fractured bones.
In conclusion, both the assertion and reason are true, and the reason correctly explains the assertion. Plaster of Paris is indeed used by doctors for setting fractured bones because it can be easily molded, sets into a hard mass, and provides support and immobilization to the fractured area.
Reason (R): When Plaster of Paris is mixed with water and applied around the fractured limbs, it sets into a hard mass.
The correct answer is option A, which states that both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion (A).
