Chapter 29. EMT

Which of the following scenarios is an example of a direct injury?

A passenger fractures her patella after it strikes the dashboard.

Which of the following statements regarding compartment syndrome is correct?

Compartment syndrome typically develops within 6 to 12 hours after an injury.

Which of the following statements regarding striated muscle is correct?

It forms the major muscle mass of the body and usually crosses at least one joint.

A subluxation occurs when

a joint is incompletely dislocated.

During your assessment of a 29-year-old female with significant deformity to her left elbow, you are unable to palpate a radial pulse. Your transport time to the hospital is approximately 40 minutes. You should:

apply gentle manual traction in line with the limb and reassess for a pulse.

A 76-year-old male experienced sudden pain to his left thigh when he was standing in line at the grocery store. Your assessment reveals ecchymosis and deformity to the distal aspect of his left femur, just above the knee. Distal circulation and sensory and motor functions are intact. The MOST appropriate method of splinting this injury involves:

applying padded board splints to both sides of the leg.

In moving joints, the ends of the bones are covered with:

articular cartilage.

You receive a call to a local gymnasium for a basketball player with a dislocated shoulder. Upon arrival, you find the patient, a 17-year-old male, sitting on the ground. He is holding his left arm in a fixed position away from his body. There is an obvious anterior bulge to the area of injury. You should

assess distal pulse, motor, and sensory functions.

A 21-year-old male was thrown over the handlebars of his motorcycle when he rear- ended a car that was stopped at a red light. He was wearing a helmet, which he removed prior to your arrival. He is conscious, but restless, and has closed deformities to both of his femurs. His skin is pale, his heart rate is rapid and weak, and his respirations are rapid and shallow. In addition to applying high-flow oxygen and protecting his spine, you should:

bind his legs together on the backboard, keep him warm, and transport without delay.

Which of the following structures is regulated by smooth muscle?

blood vessels

The musculoskeletal system refers to the:

bones and voluntary muscles of the body.

A fracture is MOST accurately defined as a(n

break in the continuity of the bone.

When caring for a patient with a possible fracture of the scapula, the EMT should:

carefully assess the patient for breathing problems.

The MOST commonly fractured bone(s) in the body is the:

clavicle.

When assessing a patient with a possible fracture of the leg, the EMT should

compare it to the uninjured leg.

When assessing a patient with a possible fracture of the leg, the EMT should:

compare it to the uninjured leg.

A 54-year-old male accidentally shot himself in the leg while cleaning his gun. Your assessment reveals a small entrance wound to the medial aspect of his right leg. The exit wound is on the opposite side of the leg and is actively bleeding. The patient complains of numbness and tingling in his right foot. You should:

control the bleeding and cover the wound with a sterile dressing.

Common signs and symptoms of a sprain include all of the following, EXCEPT:

deformity.

The disruption of a joint in which the bone ends are no longer in contact is called a:

dislocation.

Which of the following musculoskeletal injuries would MOST likely result in deformity?

displaced fracture

A supracondylar or intercondylar fracture is also known as a fracture of the:

distal humerus.

Assessing a person's neurovascular status following a musculoskeletal injury includes all of the following, EXCEPT:

evaluating proximal pulses.

Traction splints are used primarily to immobilize and secure fractures of the:

femur.

In which of the following situations should the EMT splint an injured limb in the position of deformity?

if resistance is encountered or the patient experiences severe pain

A 17-year-old football player collided with another player and has pain to his left clavicular area. He is holding his arm against his chest and refuses to move it. Your assessment reveals obvious deformity to the midshaft clavicle. After assessing distal pulse, sensory, and motor functions, you should

immobilize the injury with a sling and swathe.

A 17-year-old football player collided with another player and has pain to his left clavicular area. He is holding his arm against his chest and refuses to move it. Your assessment reveals obvious deformity to the midshaft clavicle. After assessing distal pulse, sensory, and motor functions, you should:

immobilize the injury with a sling and swathe.

During your rapid secondary assessment of a 19-year-old female with multiple trauma, you note bilateral humeral deformities and a deformity to the left midshaft femur. Her skin is diaphoretic and her pulse is rapid and weak. Your partner has appropriately managed her airway and is maintaining manual stabilization of her head. The MOST appropriate treatment for this patient includes:

immobilizing her to a backboard and rapidly transporting.

When splinting a possible fracture of the foot, it is MOST important for the EMT to:

leave the toes exposed.

The MOST common and significant complication associated with fractures or dislocations of the knee is:

ligament and cartilage damage.

Bones are connected to other bones by bands of tough fibrous tissues called:

ligaments.

A person who experiences a calcaneus fracture after jumping and landing on his or her feet would MOST likely experience an accompanying fracture of the

lumbar spine.

Which of the following musculoskeletal injuries would pose the greatest threat to a patient's life?

pelvic fracture with hypotension

The MOST reliable indicator of an underlying fracture is:

point tenderness.

Crepitus and false motion are

positive indicators of a fracture.

A 45-year-old female was the unrestrained passenger of a small car that rear-ended another vehicle at a moderate rate of speed. She is conscious and alert, but complains of pain to both of her knees. There is visible damage to the dashboard on the passenger's side of the vehicle. In addition to fractures or dislocations of the knees, you should be MOST suspicious for:

posterior hip dislocation.

The primary purpose for splinting a musculoskeletal injury is to:

prevent further injury.

A "hip" fracture is actually a fracture of the

proximal femur.

A "hip" fracture is actually a fracture of the:

proximal femur.

The PASG is absolutely contraindicated in patients who have:

pulmonary edema.

Applying ice to and elevating an injured extremity are performed in order to:

reduce pain and swelling.

The pectoral girdle consists of the.

scapulae and clavicles.

The pectoral girdle consists of the:

scapulae and clavicles.

Which of the following types of muscle is under direct voluntary control of the brain?

skeletal

Which of the following joints allows no motion?

skull sutures

What type of muscle contracts and relaxes to control the movement of the contents within its structures?

smooth

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

sprain

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.

sprain

A 22-year-old female was ejected from her car after striking a tree head-on. As you approach her, you note obvious closed deformities to both of her femurs. She is not moving and does not appear to be conscious. You should:

stabilize her head and perform a primary assessment.

During your rapid secondary assessment of a 30-year-old male who fell 25′, you note crepitus when palpating his pelvis. Your partner advises you that the patient's blood pressure is 80/50 mm Hg and his heart rate is 120 beats/min and weak. After completing your assessment, you should:

stabilize the pelvis with a pelvic binder and protect the spine.

Skeletal muscle is also referred to as __________ muscle.

striated

Deformity caused by a fracture would MOST likely be masked by:

swelling.

An open fracture is MOST accurately defined as a fracture in which:

the overlying skin is no longer intact.

If a dislocated shoulder has spontaneously reduced before your arrival, the only way to confirm the injury is by noting:

the patient history.

If a dislocated shoulder has spontaneously reduced before your arrival, the only way to confirm the injury is by noting

the patient history.

In general, musculoskeletal injuries should be splinted before moving the patient unless:

the patient is clinically unstable.

The act of pulling on a body structure in the direction of its normal alignment is called:

traction.
