Unit 5 Trauma Part 2 Chapters 31-34 Flashcards
A 37-year-old male sustained blunt trauma to the left anterolateral chest. He is conscious, but confused, and complains of pain during inspiration; his respirations are shallow. Your assessment reveals crepitus to the area of impact. Breath sounds, although weakly audible, are bilaterally equal. The pulse oximeter reads 89% on room air. You should:

d. penetrating injuries to the upper chest often result in liver lacerations.
a. the diaphragm may elevate as high as the nipple line upon exhalation.
A 22-year-old male with blunt thoracic trauma presents with severely labored respirations. His level of consciousness is decreased, and his heart rate is 140 beats/min and thready.

A construction worker is pinned between a truck and a loading dock. He is conscious and in respiratory distress. Further assessment reveals upper torso and facial cyanosis and bilateral conjunctival hemorrhages. When treating this patient, you must:
Select one:

A trauma patient who presents with shock, jugular venous distention, and bilaterally equal breath sounds has most likely experienced a: Select one: a. pericardial tamponade. b. pulmonary contusion. c. massive hemothorax. d. simple pneumothorax.

Which of the following is a late sign of a tension pneumothorax? Select one: a. Profound shortness of breath b. Contralateral tracheal shift c. Narrowing pulse pressure d. Bulging intercostal muscles

Commotio cordis is a condition in which:
Select one:
a. shearing forces tear the aorta from its point of attachment, resulting in profound intrathoracic hemorrhage.
b. immediate cardiac arrest occurs when the chest is impacted during the heart’s repolarization period.
c. increased intrathoracic pressure causes the intercostal muscles to bulge from in between the ribs.
d. a patient takes a deep breath just before blunt trauma to the chest, resulting in rupture of one or both lungs.
b. immediate cardiac arrest occurs when the chest is impacted during the heart’s repolarization period.
A 40-year-old male experienced penetrating trauma to the left anterior chest. During inhalation, you note that his radial pulses become barely palpable. You should suspect: Select one: a. aortic disruption. b. cardiac tamponade. c. hemopneumothorax. d. myocardial contusion.
b. cardiac tamponade.
Chest trauma is a common cause of respiratory acidosis and rapidly leads to death because the:
Select one:
a. kidneys fail and are unable to normalize the blood’s pH.
b. pH level of the blood increases precipitously.
c. renal system cannot compensate quickly enough.
d. body eliminates CO2 more rapidly than it is produced.
c. renal system cannot compensate quickly enough.
Which of the following statements regarding the parietal pericardium is correct?
Select one:
a. It forms the pericardium and is in direct contact with the myocardium and vena cava.
b. It cannot distend acutely but can slowly distend with as much as 1,000 mL of blood.
c. It acutely distends with as little as 500 mL of blood or excess pericardial fluid.
d. It is a thin fibrous sac that encases the heart and normally contains 200 mL of fluid.
b. It cannot distend acutely but can slowly distend with as much as 1,000 mL of blood.
