Which type of fracture occurs when the bone is crushed and shattered into multiple fragments?
Greenstick fracture
Comminuted fracture
Avulsion fracture
Stress fracture
The Correct Answer is B
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.

a. Hypertension: Hypertension is a condition characterized by high blood pressure and is not directly associated with an increased risk of fractures.
b. Diabetes mellitus: Diabetes mellitus is a metabolic disorder that affects blood sugar levels and does not directly increase the risk of fractures.
d. Asthma: Asthma is a respiratory condition that affects the airways and lungs and is not linked to an increased risk of fractures.
Correct Answer is B
Explanation
The type of fracture is essential in assessing the patient's readiness for weight-bearing. Some fractures require non-weight-bearing, partial weight-bearing, or full weight-bearing, depending on the bone's location, severity of the fracture, and treatment plan.
a. Age of the patient: The patient's age can influence fracture healing but is not the primary factor in determining weight-bearing status.
c. Pain level: Pain assessment is important for managing discomfort, but it is not the sole factor in determining weight-bearing status.
d. Patient's occupation: The patient's occupation may be considered in the treatment plan, but it is not the primary factor in determining weight-bearing status after a fracture.
