Name 2 biological, 3 extrinsic, and 1 behavioral factor that can predispose
a patient to a fracture. - 🧠 ANSWER ✔✔Biological:
1) Age: bone structure becomes less dense/more susceptible to injury
,2) Type of bone involved: some are better equipped to handle difference
stresses and forces without injury
Extrinsic:
1) Amount of force applied
2) Angle of force applied
3) Duration of force
Behavioral:
1) Participating in adrenalin-seeking activities such as skydiving, rock-
climbing, motor cross
Describe nursing instructions that may be given to a patient in a cast. - 🧠
ANSWER ✔✔1) Cast should be kept dry.
2) Monitor the skin areas at the end of the cast.
3) Never stick anything into or under the cast to scratch or itch.
,4) Alert medical care in case of tightness or increasing pain, numbness,
color change, or temperature change in areas of distal ends of cast.
5) Follow up if cast gets loose or cracks.
What is the basic anatomy of a long bone? - 🧠 ANSWER ✔✔Typically has
two main components:
1) Diaphysis - makes up long shaft of bone. Outer portion is made of
compact bone. Inner layer is made of marrow.
2) Epiphyses - set at either end of long bone. Outer layer is compact bone
and inner core is spongy bone.
Periosteum - membrane that lines both externally. - contains supply of
nerve fibers, lymph, blood vessels
Give examples of tapping fracture and penetrating fracture. - 🧠 ANSWER
✔✔1) Tapping - sustained from a small force to a concentrated area. Bone
will absorb this force - may or may not be mild soft tissue display of injury.
EX: fracture of forearm when blocking a hit with a fist or bat; being kicked in
lower leg

, 2) Penetrating - caused by large amount of force on small area. Object of
force is usually small and soft tissue involvement is minimal.
EX: stab wound, gunshot wound
Different from crush wound because object of force is much larger.
List several factor that determine fracture-healing outcome. - 🧠 ANSWER
✔✔1) Skeletal maturity decreases healing.
- Immature skeleton increases rate and success of healing.
2) Single bone fracture has better prognosis than multi-bone fracture.
3) Big displacement that affect surrounding tissues requires more healing
time.
4) Thoracic spine injury heals better than unstable lumbar/cervical spine
injuries.
5) Fracture of joint surfaces are more unstable/difficult to treat.
6) Fracture with nearby unaffected support bone has good prognosis - acts
as natural splint.
