ISCD Exam - Osteoporosis With Questions And
100% Correct Answers
Effects of osteoporosis - Answer Increased risk for fragility fractures --> disability,
dependence, delirium, dementia, & death
Why use a DXA in the context of osteoporosis? (4) - Answer National Osteoporosis
Foundation (NOF) relies on DNA for treatment thresholds because it's cost effective,
gives off low radiation exposure, excellent accuracy and reproducibility, and can
diagnose osteoporosis before a fracture occurs
Fragility fractures
- AKA
- Define - Answer AKA Low trauma fractures
Fractures caused by the force of a fall from standing height OR a bone that breaks
under circumstances that would not typically cause the bone to break
NIH definition of osteoporosis - Answer A skeletal disorder characterized by
compromised bone strength, predisposing one to an increased risk of fracture
The first guidelines on osteoporosis were written when, by who? - Answer In 1998, by
the National Osteoporosis Foundation
Bone strength reflects the integration of two main features: - Answer Bone density (can
be measured, i.e. with the DXA) and bone quality (hard to quantify)
T or F: There are no symptoms of low bone mass until fracture occurs - Answer True
, WHO definition of post-menopausal osteoporosis (T-Scores) - Answer Normal: >/= -1.0
Low bone mass (osteopenia): -1.0 to -2.5
Osteoporosis: </= -2.5
Severe osteoporosis: </= -2.5 with fracture
As used by the WHO to identify osteoporosis, what does the T-score compare? - Answer
An individual's BMD with the mean value for a healthy 30 year-old adult
Expresses the difference as a standard deviation score (sites include lumbar spine, total
hip, femoral neck, and 1/3 radius site)
Functions of the skeleton (5) - Answer Supports the body
Protects internal organs
Attaches to muscles to enable movement
Provides cavities for blood formation
Provides reservoir for minerals
The central skeleton includes... - Answer Axial skeleton, plus hips and shoulders (spine,
ribs, pelvis, hips, and shoulders)
The peripheral skeleton includes... - Answer Appendicular skeleton, minus hips and
shoulders (extremities, i.e. arms and legs)
The central skeleton is made up of mostly _____ or ______ bone, which makes up the
inner parts of the bones - Answer Cancellous or trabecular bone
The peripheral skeleton is made up of mostly _____ or _____ bone, which makes up the
outer envelope of all bones and the shafts of the long bones - Answer cortical or
compact bone
