During your reassessment, you find that the patient is now confused, hypotensive, and profusely diaphoretic. What is MOST likely causing this patient's deterioration?

compression of the aorta and vena cava

Hemoptysis is defined as:

coughing up blood.

The thoracic cavity is separated from the abdominal cavity by the

diaphragm.

engorged jugular veins

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

hematemesis.

lungs

hemoptysis indicates damage to the

minute volume will decrease

if a person's tidal volume decreases, but his or her respiratory rate remains unchanged

immediately request ALS support

The MOST critical treatment for a tension pneumothorax involves:

inserting a needle through the rib cage into the pleural space.

pleurisy

irritation or damage to the pleural surfaces that causes sharp chest pain during inhalation is called:

hemothorax

is the result of blood accumulating in the plueral space after a traumatic injury when the vessels of the lung are lacerated and leak blood

simple pneumothorax

is the result of blunt trauma, such as fractured ribs

You arrive at the scene of a major motor vehicle crash. The patient, a 50-year-old female, was removed from her vehicle prior to your arrival. Bystanders who removed her state that she was not wearing a seatbelt. The patient is unconscious, tachycardic, and diaphoretic. Your assessment reveals bilaterally clear and equal breath sounds, a midline trachea, and collapsed jugular veins. You should be MOST suspicious that this patient has experienced a

laceration of the aorta

partially remove the dressing.

Which of the following organs or structures does NOT reside within the mediastinum?

Tachypnea

rapid respirations

A patient who presents with profound cyanosis following a chest injury:

requires prompt ventilation and oxygenation.

When assessing a patient with a hemothorax, you will MOST likely find:

signs and symptoms of shock.

During your assessment of a patient with blunt chest trauma, you note paradoxical movement of the left chest wall. As your partner is administering oxygen to the patient, you should:

stabilize the chest wall with a bulky dressing.

Elevation of the rib cage during inhalation occurs when

the intercostal muscles contract.

Elevation of the rib cage during inhalation occurs when:

the intercostal muscles contract.

increases the risk of internal injury

the pliability of the pediatric rib cage

inserting a needle through the rib cage into the pleural space

the treatment for relieving a tension pneumothorax involves

myocardial contusion -bruising of the heart muscle after traumatic injury

this condition may have the same signs and symptons as a heart attack, including an irregular pulse, this injuryis an injury to the heart muscle from trauma not from a heart attack

flail chest segment postive-pressure ventilation

three or more ribs broken in two or more places what ventilation may be particularly important for a patient with a flail chest that compromises ventilation

Immediate death from blunt chest trauma following a motor vehicle crash is MOST often the result of

traumatic aortic rupture.

A 19-year-old male is unresponsive, apneic, and pulseless after being struck in the center of the chest with a softball. Based on the mechanism of injury, what MOST likely occurred?

ventricular fibrillation when the impact occurred during a critical portion of the cardiac cycle

Pleural fluid is contained between the:

visceral and parietal pleurae.

pulmonary contusion-bruising of or injury to lung tissue after traumatic injury

what may interfere with oxygen exchange in the lung tissue

open pneumothorax

when a penetrating injury creates a hole in the chest wall, you may hear a sucking sound as the patient inhales this is called

signs and symptons of shock

when assessing a patinet with a hemothorax, you will MOST likely find

cardiac tamponade

when blood collects in the space between the pericardial sac and the heart. this condition results in pressure building up inside the pericardial sac until the heart cannot pump effectively; cardiac arrest may occur quickly
