Week 9 - Orthopedic Trauma Quiz

The sudden twisting of a joint beyond its normal range of motion , causing a temporary subluxation , is called a :

sprain

An open - book pelvis fracture has the potential for massive blood loss because the :

volume of the pelvis is increased

Which of the following is a risk factor for developing a stress fracture ?

Endocrine dysfunction

A 45 - year - old patient who fell off a ladder reports that they landed on their feet . Upon assessing the patient , you suspect a pelvic fracture . Which type of injury did the patient experience ?

Indirect

Which of the following musculoskeletal injuries would most likely occur together ?

Knee dislocation and tibial fracture

What type of fracture occurs at an angle across the bone and is typically caused by direct or twisting force ?

Oblique

Avascular necrosis is a major complication of a fracture of which bone ?

Scaphoid

Treatment for suspected compartment syndrome includes :

IV boluses of a crystalloid solution

Isolated musculoskeletal injuries

often result in short- or long - term disability .

Closed bilaterally fractured femurs can result in internal blood loss of up to :

1,500 mL

Heat therapy should generally be avoided how many hours after a musculoskeletal injury because it may increase pain and swelling during this period ?

48 to 72 hours

Immediate pain from the heel to the calf and a sudden inability for plantar flexion of the foot is most indicative of :

Achilles tendon rupture

Which type of fracture is unique to children and is most commonly seen in the distal radius ?

Buckle✔

If musculoskeletal injuries in the extremities are suspected , you should assess for which of the following before and after any manipulation as well as frequently during transport ?

Circulatory changes

A 68 - year - old woman presents with an acute onset of dyspnea and sharp chest pain . Her medical history is significant for a hip replacement 2 weeks ago . The patient is conscious and alert , with a blood pressure of 112/58 mm Hg , pulse rate of 90 beats / min and irregular , and labored respirations at 22 breaths min . Which of the following treatment interventions is most appropriate for this patient

Oxygenation and ventilation support and rapid transport

Which of the following structures supports 90 % of the weight of the upper body ?

Tibia

A subluxation occurs when

a joint is partially dislocated

In females , a decrease in bone density is accelerated :

after menopause

While palpating an extremity , you note a pulsatile expanding hematoma , diminished distal pulses , and a palpable thrill over the site of the injury that correlates with the patient's heartbeat . You recognize that these are signs of :

an arterial injury

A pathologic fracture occurs when

an occult medical condition causes abnormal bone weakness

When a person jumps from a height and lands on their feet , direct trauma occurs to the :

calcaneus

The best way to detect deformity or any other abnormality in an injured extremity is to

compare it to the extremity on the opposite side .

When assessing distal pulses in a patient with a lower extremity injury , it is most important to :

compare the strength of the pulses in both lower extremities

Upon palpating the clavicle of a patient with a suspected fracture , you hear a faint grating sound . You identify this as :

crepitus

The first step in caring for a musculoskeletal injury involves :

exposing and assessing the injury site

A 40 - year - old woman has an unstable pelvis following a motor vehicle crash . She is conscious but confused . Her blood pressure is 80/50 mm Hg , pulse is 120 beats / min and weak at the radial arteries and respirations are 24 breaths / min and shallow . After starting at least one large - bore IV line , you should :

give enough isotonic crystalloid fluids to improve her mental status and radial pulse quality

The most significant immediate risk associated with an open fracture is

hemorrhage

Swelling and inflammation associated with musculoskeletal injuries are reduced :

if cold packs are applied during the acute stage of the injury .

A young man has an isolated injury to his left leg . Your assessment reveals obvious deformity and ecchymosis . Distal circulation as well as motor and sensory functions , are grossly intact , and the patient is hemodynamically stable . In addition to stabilizing the suspected fracture site , you should

immobilize the knee and the ankle

In contrast to osteoarthritis , rheumatoid arthritis :

is a systemic inflammatory disease that affects joints and other body systems .

A patient standing with their head cocked toward a knocked - down left shoulder most likely has a fracture of the :

left clavicle

You have applied board splints to a suspected leg fracture in a young woman and have given her fentanyl for pain . En route to the hospital the patient states that the pain is excruciating Further narcotics fail to relieve the pain . Reassessment of the injured area reveals that the overlying skin is taut and the pedal pulse is weak . You should :

loosen the splint , elevate the leg apply ice and notify the hospital

You arrive at the scene of a motorcycle crash and find the rider lying supine approximately 20 feet from his bike ; he is still wearing his helmet . As you approach him , you note that he has bilaterally deformed femurs . You should :

manually stabilize his head and assess his airway

A 71 - year - old man slipped on wet grass and landed on his left side . He denies losing consciousness before or after the fall and is presently conscious and alert . He complains of pain to his left hip and in his neck . Your assessment reveals a hematoma to the left side of his head and an external rotation and shortening of his left leg . His vital signs are stable . The most appropriate treatment for this patient includes :

oxygen if hypoxemic , spinal motion restriction precautions an IV line of normal saline , stabilization of his hip with pillows , fentanyl if needed , and transport

The appendicular skeleton is composed of the :

pectoral girdle , pelvic girdle , and bones of the extremities .

Compartment syndrome occurs when

pressure in the fascial compartment leads to impaired circulation , sensory changes , and progressive muscle death

After ensuring your own safety , your next priority when caring for a patient with an extremity injury is to :

prevent further injury

Upon assessing a patient , you find that they have a scapular fracture . Based on this finding , you should also assess for :

pulmonary contusions

Prior to splinting the injured extremity of a patient , you should :

remove the patient's clothing to maximize visualization of the injured area .
