Trauma Lecture 3

Question 1

function of skeletal muscles

Answer 1

• striated, voluntary
• movement
• body heat
• posture
• protection

Question 2

function of bones

Answer 2

• skeleton
• movement
• support
• mineral storage
• red blood cell production

Question 3

function of joints

Answer 3

area where two or more bones connect to allow mobility

Question 4

function of ligaments

Answer 4

• connect bone to bone
• provide stability and function

Question 5

function of tendons

Answer 5

• connect bone to muscle
• provide stability and function

Question 6

types of mechanism of injury

Answer 6

• direct blows
• indirect forces
• twisting forces
• crush injury

Question 7

what is a sprain

Answer 7

ligaments

Question 8

what is a strain

Answer 8

muscle

Question 9

what is a fracture

Answer 9

bone

Question 10

closed injuries

Answer 10

does not break the skin

Question 11

what is a dislocation

Answer 11

disruption of a jointi n which the bone ends are no longer in contact

Question 12

open injuries

Answer 12

breaks the skin

Question 13

what can we splint

Answer 13

• joints: splint the long bone above and below
• long bone: splint the join above and below
• reduces pain

Question 14

how to spint closed injuries

Answer 14

1. stabilize in normal anatomic position
2. do not reduce dislocations

Question 15

how to splint open injuries

Answer 15

1. stabilize in position found
2. control bleeding

Question 16

where are common fractures located

Answer 16

• hip
• pelvis
• femur

Question 17

what are common fracture complications

Answer 17

• compratment syndrome
• blood loss
• multi-system trauma

Question 18

what are hip fractures

Answer 18

• shortening of the leg with external rotation
• extremely painful
• potential for bleeding

Question 19

treatment for hip fracture

Answer 19

• pain management
• monitor for bleeding/shock

Question 20

what are pelvic fractures

Answer 20

• instability = potential fracture
• extremely painful
• potential for internal

Question 21

treatment for pelvic fracture

Answer 21

• stabilization with pelvic binder
• pain management
• monitor for shock

Question 22

what are femur fractures

Answer 22

• midshaft, closed femur fracture
• interna rotation

Question 23

treatment for femur fracture

Answer 23

• traction splint
• realignment of the bone

Question 24

compartment syndrome

Answer 24

• restriction of blood flow to injured area due to swelling
• edema
• bleeding
• constriction
• bandaging or splinting

Question 25

complications of compartment syndrome

Answer 25

* blood loss * multi-system trauma * splinting is always secondary to life threats * if there is a high velocity mechanism of injury, transport likey takes priority

Question 26

types of splint

Answer 26

* rigid (cardboard) * vacuum * sling and swathe * traction splint * pelvic binder
