What is the definition of a fracture?
A dislocation of a joint
A break in the continuity of a bone
A stretching or tearing of ligaments
A separation of bone fragments at a joint
The Correct Answer is B
A fracture is a break in the continuity of a bone, resulting from excessive force or stress applied to the bone. It is different from a dislocation, which involves the displacement of bone from its normal position at a joint.
a. A dislocation of a joint: A dislocation involves the displacement of bone from its normal position at a joint and is not the same as a fracture.
c. A stretching or tearing of ligaments: A stretching or tearing of ligaments is known as a sprain, not a fracture.
d. A separation of bone fragments at a joint: This description is more in line with a dislocation, where the bone separates from its normal position at a joint.

Correct Answer is C
Explanation
In a greenstick fracture, the bone bends and partially breaks, usually occurring in children due to the flexibility of their bones.
a. Transverse fracture: A transverse fracture occurs when the bone breaks straight across its long axis, not bending.
b. Oblique fracture: An oblique fracture involves a diagonal break, not bending and partial breaking.
d. Avulsion fracture: An avulsion fracture occurs when a piece of bone is torn away by a ligament or tendon, not bending and partial breaking.
Correct Answer is A
Explanation
Localized swelling and bruising are common signs of inflammation and injury at the fracture site. They may indicate the presence of a fracture, especially if the patient experienced trauma or a fall.
b. Warmth and redness at the site: Warmth and redness are signs of inflammation, but they are not specific to fractures and can occur in various musculoskeletal conditions.
c. Absence of pain with movement: Absence of pain with movement is not a typical finding in fractures. Fractures usually cause pain, especially with movement.
d. Increased range of motion at the joint: Increased range of motion may occur in some injuries, but it is not a reliable indicator of a fracture, especially if there is swelling and bruising present.
