Question 1

Which of the following best describes a compound (open) fracture?

Accepted Answer

A fracture in which the bone ends penetrate through the skin, increasing the risk of infection.

Question 2

During the healing of a bone fracture, which stage is characterized by the formation of a soft callus composed of cartilage and fibrous tissue?

Accepted Answer

Fibrocartilaginous callus formation

Question 3

A 12-year-old boy fractures his femur at the growth plate. What type of fracture is this most likely to be?

Accepted Answer

Epiphyseal fracture

Question 4

Which of the following is the correct sequence of events in bone fracture healing?

Accepted Answer

Hematoma formation → Fibrocartilaginous callus formation → Bony callus formation → Bone remodeling

Question 5

A comminuted fracture is best described as:

Accepted Answer

A fracture where the bone is broken into three or more pieces.

Question 6

Which of the following is a potential complication unique to open (compound) fractures compared to closed fractures?

Accepted Answer

Increased risk of infection due to exposure of bone and tissue to the external environment.

Question 7

If a bone fracture does not break the skin and the bone ends remain aligned, how would it be classified?

Accepted Answer

Closed, aligned fracture

Question 8

Which process is responsible for restoring the bone to its original shape and structure after a fracture has healed?

Accepted Answer

Bone remodeling

Question 9

A patient presents with a fracture in which the bone is only partially broken, with one side of the bone bending. This is most likely a:

Accepted Answer

Greenstick fracture

Question 10

Which of the following best explains why hematoma formation is the first step in bone healing?

Accepted Answer

It brings in new blood vessels and nutrients necessary for healing.

Question 11

A fracture that occurs perpendicular to the long axis of the bone is called a:

Accepted Answer

Transverse fracture

Question 12

During which stage of bone healing does the conversion of fibrocartilaginous tissue to spongy bone occur?

Accepted Answer

Bony callus formation

Question 13

A 25-year-old athlete sustains a fracture from a twisting injury during a soccer game. Which type of fracture is most likely?

Accepted Answer

Spiral fracture

Question 14

Which of the following equations best represents the relationship between force, mass, and acceleration, which is relevant in understanding the mechanism of bone fractures?

Accepted Answer

$$F = m \times a$$

Question 15

A fracture that occurs along the length of the bone, parallel to its long axis, is called a:

Accepted Answer

Longitudinal fracture

Question 16

Which of the following best describes the role of the fibrocartilaginous callus during bone healing?

Accepted Answer

It provides a temporary splint that bridges the broken bone ends.

Question 17

A patient with osteoporosis is more likely to experience which type of fracture due to weakened bone structure?

Accepted Answer

Comminuted fracture

Question 18

Which of the following is NOT a correct step in the bone healing process?

Accepted Answer

Osteoclast apoptosis

Question 19

A fracture in which the bone ends are out of normal alignment is called a:

Accepted Answer

Non-aligned fracture

Question 20

Which of the following clinical signs would most likely indicate the presence of a hematoma at a fracture site?

Accepted Answer

Swelling and discoloration due to blood accumulation
