Which type of fracture involves the bone breaking into multiple fragments?
Comminuted fracture
Greenstick fracture
Spiral fracture
Transverse fracture
The Correct Answer is A
A comminuted fracture is a type of fracture where the bone breaks into multiple fragments. This can occur due to a high-impact injury or significant force applied to the bone.
b. Greenstick fracture: A greenstick fracture is an incomplete fracture seen in children, where the bone bends and partially breaks on one side but remains intact on the other side.
c. Spiral fracture: A spiral fracture occurs when the bone is twisted, causing a spiral-shaped fracture line. It often results from a twisting force applied to the bone.
d. Transverse fracture: A transverse fracture is a type of fracture where the fracture line is perpendicular to the long axis of the bone.

Correct Answer is B
Explanation
A transverse fracture occurs when the bone breaks straight across its long axis, perpendicular to the bone's length.
a. Greenstick fracture: A greenstick fracture involves the bone bending and partially breaking, usually seen in children. It does not break straight across the bone.
c. Oblique fracture: An oblique fracture involves a diagonal break, not straight across the bone's long axis.
d. Comminuted fracture: In a comminuted fracture, the bone breaks into multiple pieces, which is different from breaking straight across the bone.
Correct Answer is C
Explanation
Calcium supplements are commonly prescribed to promote bone healing in patients with fractures. Adequate calcium intake is essential for bone repair and regeneration.
a. Nonsteroidal anti-inflammatory drugs (NSAIDs): NSAIDs may help manage pain and inflammation, but they do not directly promote bone healing and may even inhibit it in some cases.
b. Antibiotics: Antibiotics are prescribed to treat or prevent infection, but they do not play a direct role in bone healing unless an infection is present.
d. Bisphosphonates: Bisphosphonates are used to treat osteoporosis and other bone disorders but are not typically prescribed specifically for fracture healing.
