What is a closed fracture?
A fracture where the bone breaks through the skin
A fracture where the bone is out of alignment
A fracture where the bone is completely broken in two
A fracture where the skin remains intact over the fractured bone
The Correct Answer is D
A closed fracture is a fracture where the skin remains intact over the fractured bone, and there is no open wound at the site of the fracture.
a. A fracture where the bone breaks through the skin: This type of fracture is known as an open or compound fracture, where the bone pierces through the skin.
b. A fracture where the bone is out of alignment: This type of fracture is known as a displaced fracture, where the bone fragments are not aligned properly.
c. A fracture where the bone is completely broken in two: A complete fracture refers to a fracture that results in two separate bone fragments, but it does not necessarily involve the skin.

Correct Answer is B
Explanation
A comminuted fracture occurs when the bone is crushed and shattered into multiple fragments, resulting in significant bone displacement and increased difficulty in alignment during the healing process.
a. Greenstick fracture: A greenstick fracture is an incomplete fracture where the bone bends and partially breaks, commonly seen in pediatric patients. It does not involve bone crushing or fragmentation.
c. Avulsion fracture: An avulsion fracture occurs when a small fragment of bone is pulled away from the main bone due to the forceful attachment of a tendon or ligament. It is not characterized by bone crushing or fragmentation.
d. Stress fracture: A stress fracture is a tiny crack in the bone caused by repetitive stress and overuse. It does not involve bone crushing or fragmentation.
Correct Answer is C
Explanation
Smoking is associated with an increased risk of fractures because it can negatively impact bone health, reduce bone density, and impair bone healing.
a. Adequate calcium intake: Adequate calcium intake is essential for maintaining strong bones and reducing the risk of fractures, so it is not associated with an increased risk.
b. Regular weight-bearing exercise: Regular weight-bearing exercise helps improve bone density and reduces fracture risk, so it is not associated with an increased risk.
d. Maintaining a healthy body weight: Maintaining a healthy body weight is beneficial for overall health, but it is not specifically associated with an increased risk of fractures.
