Ch 30 Musculoskeletal Flashcards

1
Q

5 functions of the musculoskeletal system

A
  1. Give body its shape
  2. Protect internal organs
  3. Provide for movement
  4. Stores salts and other minerals for metabolism
  5. Produce Red Blood Cells necessaary for oxygen

Q

force impacts on one end of a limb causing injury some distance away from the point of impact.

A

indirect force

17
Q

T/F
severe bleeding associated with afractured pelvis or femur often occurs from the bone itself not from the lacerated vsl outside the tissue

A

true

18
Q

red marrow produces

A

red blood cells

19
Q

sound of feeling broken fragments of bone grinding agaisnt each other

A

crepitus

20
Q

pt complaining of numbness or a tingling sensation

A

paresthesia

21
Q

2 basic reasons for splinting a bone

A

prevents movement

reduces chance of further injury

22
Q

T/F

both before and after you apply a splint assess the pulse, moto function and sensation distal to the injury

A

True

23
Q

commericially manufactured splints made of wood, plastic, cardboard, compressed wood designed with velcro straps

A

rigid splints

24
Q

splints that are soft and pliable being inflated but rigid once filled with air
cannot be sized, impair circulation, interfere with ability to access pulse

A

pressure (air or pneumatic) splints

25
Q

this provides counter pullalleviating pain, reducing blood loss, minimizing further injury

A

traction splint

26
Q

a type of rigid splint that is malleable enough to form a deformed or angulated extremity, the splint is shaped to the deformed extremity mad eof wire, aluminum, or other metal that can bend

A

formable splint

27
Q

splits easily formed to deformed extremities by sucking out the air

A

vaccum splint

28
Q

used to provide stability to a painful and tender shoulder, elbow, upper humerus

A

sling and swathe

29
Q

PASG

A

pneumatic antishock garment

used to pelvis and decrese the compartment size and reduce bleeding

30
Q

pressure in space around capillaries exceeds the pressure needed to perfuse the tissues, the blood flow is cut off and the cells become hypoxic leading to

A

compartment syndrome

usually develops overtime as edema around area increses, associated with fractures, arterial and veneous bleeding from blunt force trauma

31
Q

a pathological fracture that results from a disease that causes degeneration and dramatically weakens the bone, making it porone to fracture.
these will not present obvious evidence of trauma

A

nontraumatic fracture

32
Q

an injury to a muscle or a muscle and a tendon, possibly caused by overextension, or over stretching

A

strain

33
Q

injury to a joint capsule, with damage to or tearing of the connective tissue involves ligament

A

sprain

34
Q 
do not use traction splint if 1-2 inches above or below the knee
knee has been injured
hip  
pelvis
partial amputation
A

true
