The musculoskeletal system refers to the:
bones and voluntary muscles of the body
nervous system’s control over the muscles
connective tissue that supports the skeleton
involuntary muscles of the nervous system
Which of the following statements regarding striated muscle is correct?
Striated muscle is involuntary because you have no conscious control over it
Most of the body’s striated muscle is found within the walls of the blood vessels
Striated muscle tissue is attached directly to the bones by tough bands of cartilage
It forms the major muscle mass of the body and usually crosses at least one joint
Which of the following types of muscle is under direct voluntary control of the brain?
Cardiac
Skeletal
Smooth
Autonomic
Atrophy is a condition that occurs when:
increased use of skeletal muscle causes an increase in its strength
the tendons that attach muscle to bone become stretched or injured
muscle decreases in size and function because of disease or trauma
carbon dioxide, lactic acid, and other wastes accumulate in the muscle
Bone marrow produces:
platelets
blood cells
lymphocytes
electrolytes
A ____________ is a musculoskeletal injury in which there is partial or temporary separation of the bone ends as well as partial stretching or tearing of the supporting ligaments
Strain
Sprain
Fracture
Dislocation
A fracture caused by minimal force that is associated with diseases such as cancer and osteoporosis is called a __________ fracture
greenstick
pathologic
transverse
comminuted
A(n) __________ fracture occurs in the growth section of a child’s bone and might lead to bone growth abnormalities.
greenstick
diaphyseal
epiphyseal
metaphyseal
The act of pulling on a body structure in the direction of its normal alignment is called:
traction
reduction
stabilization
immobilization
Traction splints primarily immobilize and secure fractures of the:
hip
pelvis
femur
humerus
The most commonly fractured bone(s) in the body is the:
clavicle
scapula
radius and ulna
midshaft femur
Which of the following fractures has the greatest potential for internal blood loss and shock?
Hip
Femur
Pelvis
Humerus
When splinting a possible fracture of the foot, it is most important for the EMT to:
use a pillow as a splint
leave the toes exposed
apply a pneumatic splint
observe for tissue swelling
In which of the following situations should the EMT splint an injured limb in the position of deformity?
When distal circulation and neurological functions are absent
If transport time to the hospital is greater than 20 to 30 minutes
If resistance is encountered or the patient experiences severe pain
If a traction splint will be used to immobilize the injured extremity
Of the following musculoskeletal injuries, which is the least severe?
Nondisplaced pelvic fracture
Open fractures of a long bone
An amputation of an extremity
Multiple closed long bone fractures
Skeletal muscle is also referred to as __________ muscle
smooth
striated
connective
involuntary
Skeletal muscle is attached to the bone by tough, ropelike fibrous structures called:
fascia
tendons
cartilage
ligaments
Which of the following structures is regulated by smooth muscle?
Heart
Skeleton
Blood vessels
Diaphragm
Common signs and symptoms of a sprain include all of the following, except:
swelling
deformity
ecchymosis
guarding
Which of the following statements regarding compartment syndrome is correct?
Compartment syndrome typically develops within 6 to 12 hours after an injury
Compartment syndrome occurs because of increased pressure within the bone cavity
In most cases, compartment syndrome develops within a few minutes after an injury
Most cases of compartment syndrome occur following a severe fracture of the pelvis
