Which of the following is NOT listed as a potential cause of a bone fracture?

• A. Severe trauma
• B. Bone tumours
• C. Metabolic Bone Disease
• D. Dehydration

Answer: (D)

When a bone breaks, it’s usually because something directly weakens the bone or applies force beyond what the bone can handle. Severe trauma is a clear example of this—an accident or impact can exceed the bone’s strength and cause a fracture. Bone tumours are another way bones can become weak because they destroy or deform bone tissue, making fractures more likely even with normal activity. Metabolic bone disease reduces bone density or quality, so bones are inherently more fragile and prone to breaking under stress.

Dehydration, however, doesn’t directly weaken bone or create a fracture by itself. It affects hydration, circulation, and overall organ function, but it isn’t a direct cause of bone fractures in the context of first aid. So the option describing dehydration is not a listed potential cause of a bone fracture.
