1.
A 6-year-old child is brought to the trauma bay after being struck by a vehicle. He
has respiratory distress, tachycardia, decreased breath sounds on the left, and
oxygen saturation of 82%. What is the most appropriate immediate action?
A. Obtain a chest radiograph
B. Perform a computed tomography scan of the chest
C. Perform immediate decompression of the suspected tension pneumothorax
D. Observe the child while administering oxygen
Answer: Perform immediate decompression of the suspected tension
pneumothorax
Rationale: In a child with severe respiratory compromise and clinical findings
consistent with tension pneumothorax, treatment should not be delayed for
imaging. Immediate decompression followed by definitive chest drainage is
required.
2.
Which feature makes pediatric patients particularly susceptible to significant
thoracic injury despite the absence of rib fractures?
,A. Increased chest wall rigidity
B. Greater chest wall compliance
C. Reduced pulmonary blood flow
D. Increased skeletal mineralization
Answer: Greater chest wall compliance
Rationale: The pediatric chest wall is more compliant than the adult chest wall,
allowing substantial transmission of external force to the lungs and mediastinal
structures without obvious rib fractures.
3.
A 4-year-old child has blunt chest trauma and worsening respiratory distress.
Breath sounds are markedly decreased on the right, and the trachea appears
shifted to the left. What diagnosis is most likely?
A. Pulmonary contusion
B. Simple pneumothorax
C. Hemothorax
D. Tension pneumothorax
Answer: Tension pneumothorax
Rationale: Unilateral absent or markedly diminished breath sounds with severe
respiratory compromise and contralateral mediastinal shift is classic for tension
pneumothorax.
4.
Which thoracic injury is particularly common after significant blunt trauma in
children?
A. Flail chest
B. Aortic rupture
C. Pulmonary contusion
D. Diaphragmatic rupture
Answer: Pulmonary contusion
,Rationale: The compliant pediatric chest wall can transmit energy directly to the
lung, making pulmonary contusion common even when there are few or no rib
fractures.
5.
What is the primary initial treatment for a child with traumatic hypoxemia caused
by pulmonary contusion?
A. Immediate thoracotomy
B. Supplemental oxygen and appropriate ventilatory support
C. Routine prophylactic antibiotics
D. Immediate bronchoscopy
Answer: Supplemental oxygen and appropriate ventilatory support
Rationale: Management of pulmonary contusion is primarily supportive, with
oxygenation and ventilation maintained while avoiding unnecessary fluid
overload and excessive ventilator pressures.
6.
A child with blunt thoracic trauma develops respiratory distress several hours after
injury. Chest imaging demonstrates patchy alveolar opacities that are not confined
to a single lobe. What is the most likely diagnosis?
A. Pulmonary embolism
B. Pneumonia
C. Pulmonary contusion
D. Lung abscess
Answer: Pulmonary contusion
Rationale: Pulmonary contusions can produce patchy, nonlobar pulmonary
opacities and may become more clinically apparent during the first several hours
after trauma.
7.
, A 7-year-old child sustains penetrating trauma to the chest. He is hypotensive, has
muffled heart sounds, and has distended neck veins. Which condition should be
suspected?
A. Tension pneumothorax
B. Massive hemothorax
C. Cardiac tamponade
D. Pulmonary contusion
Answer: Cardiac tamponade
Rationale: The combination of hypotension, muffled heart sounds, and venous
distention suggests obstructive shock from pericardial blood accumulation,
although not every component of the classic triad is necessarily present.
8.
What is the preferred bedside imaging modality for rapidly assessing a child with
suspected traumatic pericardial tamponade?
A. Chest radiography
B. Computed tomography
C. Magnetic resonance imaging
D. Focused assessment with sonography for trauma
Answer: Focused assessment with sonography for trauma
Rationale: Focused ultrasound can rapidly identify pericardial fluid and is
particularly valuable in the unstable trauma patient because it can be performed
during the primary assessment.
9.
A child develops shock after penetrating chest trauma. Ultrasound reveals
pericardial fluid with signs of impaired cardiac filling. What is the major
physiologic consequence?
A. Increased left ventricular afterload only
B. Increased pulmonary vascular resistance only
