ARRT Patient Care Practice Exam

Which of the following best describes osteomalacia?

1. Affects joints

2. Softening of the bones from poor calcification

3. Affects muscle flexibility

4. Involves inflammation of bones

The correct answer is: Softening of the bones from poor calcification

Osteomalacia is best described as the softening of the bones due to inadequate mineralization, particularly a deficiency of vitamin D, calcium, or phosphate. This condition leads to a reduction in bone density and structural integrity, making bones weaker and more prone to deformities and fractures. The process of calcification is essential in maintaining healthy bone structure, and when it is impaired, it results in osteomalacia. In contrast, options that refer to joint issues or muscle flexibility do not accurately capture the essence of osteomalacia, which specifically pertains to the bones themselves and their mineral composition. Additionally, while inflammation can affect bones, it is typically more associated with conditions like osteitis or arthritis rather than osteomalacia, which primarily involves the softening and weakening of bones due to poor mineralization rather than inflammation. Therefore, option B accurately describes the condition and encompasses the critical aspect of bone health affected by osteomalacia.
