Complete Chapter Questions With Answers
Sample Questions Are Posted Below
| 1. | Disorders that affect cortical bone typically result in: | |
| A) | Fractures of long bones | |
| B) | Impaired collagen synthesis | |
| C) | Infection | |
| D) | Vertebral fractures | |
| Ans: | A | |
| Feedback: | ||
| Disorders in which cortical bone is defective or reduced in mass lead to fractures of the long bones, whereas those of cancellous bone lead preferentially to vertebral fractures. Neither process directly causes impaired collagen synthesis or infection. | ||
| 2. | The condition that contributes to the pathology of all metabolic bone diseases is: | |
| A) | Impaired vitamin D synthesis | |
| B) | Osteosarcoma | |
| C) | Infection | |
| D) | Osteopenia | |
| Ans: | D | |
| Feedback: | ||
| Osteopenia is a condition that is common to all metabolic bone diseases. Metabolic diseases are noninfectious and are not neoplastic. Impaired vitamin D synthesis can cause osteopenia, but this phenomenon is not common to all metabolic bone diseases. | ||
| 3. | A female athlete has been diagnosed with amenorrhea due to intense training for a spot on the Olympic swimming team. As a health care provider, which of the following should be implemented to prevent premature osteoporosis? | |
| A) | Encourage a minimum of 10 hours of sleep/night. | |
| B) | Increase dietary intake of protein and iron. | |
| C) | Calcium/vitamin D supplements to support BMD. | |
| D) | Watch sodium intake and eat a carb-consistent diet with lots of fruits. | |
| Ans: | C | |
| Feedback: | ||
| The female athlete triad, a pattern of disordered eating that leads to amenorrhea and eventually premature osteoporosis, is being seen increasingly in female athletes because of an increased prevalence of eating disorders. Poor nutrition, combined with intense exercise training, can lead to decrease in the critical body fat–to–muscle ratio needed for normal menses and estrogen production by the ovary. The lack of estrogen combined with the lack of calcium and vitamin D from dietary deficiencies results in a loss of bone density and increased risk of fractures. Older athletes are at high risk for osteoarthritis, a degenerative joint disorder that is unrelated loss of bone density. | ||
| 4. | For many clients, the first indication that they have osteoporosis is: | |
| A) | Bone pain that is not alleviated by rest | |
| B) | A bone fracture | |
| C) | Craving high-calcium foods | |
| D) | Decrease in range of motion in the hip and knee joints | |
| Ans: | B | |
| Feedback: | ||
| Osteoporosis is usually a silent disorder. Often, the first manifestations of the disorder are those that accompany a skeletal fracture—a vertebral compression fracture or fracture of the hip, pelvis, humerus, or other bones. The onset of the disease is not typically marked by pain or decreased range of motion. Clients with osteoporosis are not noted to crave foods that are high in calcium. | ||
