While walking, a post-menopausal grandmother falls off a curb and lands hard on

Question

While walking, a post-menopausal grandmother falls off a curb and lands hard on her outstretched right arm. Her physicians diagnose a fracture of the bone which forms the only bony connection between the upper limb and the axial skeleton. They also note damage to the joint between the fractured bone and the axial skeleton. They perform surgery to realign the bone at the fracture to allow proper healing and they use a titanium plate to permanently secure the fractured bone to the axial skeleton at the injured joint. However, they are particularly concerned because her bone mass is quite low and due to her advanced age, she also has low osteoblast activity.

Using the above passage, which will most likely improve this woman’s overall, long-term bone health?

Decreasing physical activity

Increasing dietary osteoid

Decreasing dietary vitamin D

Increasing dietary vitamin C

Using the above passage, what bone of the appendicular skeleton is fractured?

Explanation / Answer

The post menopausal woman suffered a fracture on her right upper limb. The most likely measure that will improve the bone health of this individual is increasing vitamin C (option D). Vitamin C is involved in the hydroxylation of proline and lysine residues that are involved in the formation of collagen. It also acts as an antioxidant and anti inflammatory nutrient and aids in fracture healing.

The bone that is most likely to be fractured is clavicle.
