Welcome to your 5. 🦴 Metabolic Bone Disease in Adults & Children Arena — 40 Integrated MCQs
1.
A child with metabolic bone disease has deformity at sites of rapid skeletal growth. Why are growing children particularly susceptible to the characteristic changes of rickets?
2.
A 70-year-old woman is being counselled after assessment for osteoporosis. Her dietary history suggests poor intake of calcium and vitamin D. Why is correction of this nutritional problem important as part of management?
3.
A patient with osteoporosis is prescribed a bisphosphonate. What is the principal therapeutic effect of this drug class?
4.
A child with rickets has widening of the wrists and bowing of the lower limbs. Which additional finding would support the diagnosis?
5.
A child with rickets is found to have persistent vitamin D deficiency despite apparently adequate dietary intake. Further history suggests chronic liver disease. What is the most appropriate general management principle?
6.
A 3-year-old child with rickets has significant lower-limb deformity. The parents ask whether correction of the visible deformity is the only objective of treatment. What is the best response?
7.
A child is diagnosed with nutritional vitamin D deficiency rickets. Which treatment principle is most appropriate?
8.
A mother asks how nutritional rickets can be prevented in her child. Which preventive approach is most appropriate?
9.
A child with vitamin D deficiency rickets is expected to show which biochemical pattern?
10.
Which feature best distinguishes osteomalacia from osteoporosis?
11.
An adult presents with diffuse bone pain, proximal muscle weakness and difficulty climbing stairs. Investigations suggest vitamin D deficiency. Which diagnosis is most likely?
12.
A 67-year-old woman with established osteoporosis has adequate nutrition but remains at high risk of future fragility fractures. Along with lifestyle measures, which pharmacological approach is most appropriate at undergraduate management level?
13.
An older woman with osteoporosis has chronic back discomfort and gradually worsening stooped posture. She has had no recent acute injury. Which structural consequence best explains her progressive postural change?
14.
A child with suspected rickets has low serum phosphate, elevated alkaline phosphatase and an increase in parathyroid hormone. What best explains the rise in parathyroid hormone in this setting?
15.
A 68-year-old postmenopausal woman sustains a distal radius fracture after falling from standing height. Which underlying skeletal abnormality most strongly suggests osteoporosis?
16.
A child treated for rickets returns for follow-up. The clinician reviews symptoms, growth, skeletal examination and relevant investigations. What is the main purpose of this combined reassessment?
17.
A 4-year-old child presents with bowed legs. Which part of the history is particularly useful when assessing possible nutritional rickets?
18.
A 64-year-old woman has been receiving systemic glucocorticoids for several months for a chronic inflammatory disorder. She has no current fracture but is considered at increased risk of osteoporosis. Which effect of prolonged glucocorticoid therapy contributes most directly to this risk?
19.
A 66-year-old woman with osteoporosis asks which lifestyle measure can help reduce further bone loss. Which is the most appropriate advice?
20.
A 70-year-old man is found to have osteoporosis after a low-trauma vertebral fracture. Which additional step is important in his assessment?
21.
Which laboratory abnormality is most characteristic of active nutritional rickets?
22.
A 3-year-old child with suspected rickets undergoes a wrist radiograph. Which finding would most strongly support the diagnosis?
23.
A 20-month-old child has delayed motor milestones and difficulty standing independently. Examination reveals skeletal deformity and generalized muscle weakness. Which functional problem can be explained by the metabolic bone disease itself?
24.
A clinician is assessing a child with suspected rickets. The child has skeletal deformities, but the history also reveals poor growth and delayed developmental progress. Why should growth and development be assessed in this child?
25.
An adult with osteomalacia due to vitamin D deficiency undergoes radiography because of persistent bone pain. Which finding may be seen?
26.
A 2-year-old child has growth faltering, delayed dentition, limb deformities and muscle weakness. The clinician suspects rickets but wants to identify its cause before completing treatment. Which additional history is most useful?
27.
A child with suspected nutritional rickets has poor dietary vitamin D intake and little sunlight exposure. The primary skeletal problem in rickets is:
28.
A 72-year-old woman has progressive loss of height and develops a thoracic kyphosis. Which complication of osteoporosis most likely explains these findings?
29.
A 4-year-old child with suspected rickets has difficulty walking. On examination, the clinician wants to assess the functional consequence of lower-limb disease in addition to looking for skeletal deformities. Which observation is most useful?
30.
Which intervention is particularly important for preventing fractures in an older patient with osteoporosis?
31.
During assessment of a young child with suspected rickets, the clinician notes prominence of the forehead and softening of skull bones. These findings primarily reflect:
32.
A 2-year-old child is brought with delayed walking and progressive bowing of the legs. Examination shows widening of the wrists. Which disorder is most likely?
33.
During examination of a child with suspected rickets, which musculoskeletal finding is particularly relevant?
34.
A 69-year-old man with reduced bone strength drinks excessive alcohol, smokes cigarettes and performs little physical activity. Which management approach best addresses modifiable contributors to his future fracture risk?
35.
A patient with osteomalacia related to nutritional deficiency begins appropriate replacement therapy. Which clinical change would provide useful evidence of improvement over time?
36.
A 76-year-old woman with known osteoporosis develops severe groin pain and inability to bear weight after a minor fall. Which consequence of her underlying disease is most immediately associated with major loss of mobility and independence?
37.
Which factor is most strongly associated with increased risk of osteoporosis in an elderly woman?
38.
A 3-year-old child with poor growth and lower-limb deformity is being assessed for a metabolic bone disorder. His mother reports chronic diarrhea and poor weight gain for several months. Why is this history clinically important?
39.
An adult with vitamin D deficiency has bone pain and proximal muscle weakness. Laboratory studies show increased alkaline phosphatase with biochemical evidence of disturbed calcium-phosphate homeostasis. Which underlying process best accounts for the skeletal manifestations?
40.
A 46-year-old woman presents with generalized bone discomfort and difficulty rising from a chair. She has a history of chronic intestinal malabsorption. Which mechanism most plausibly links her gastrointestinal disease to her skeletal symptoms?
