The seatbelt bruise is cosmetic and does not correlate with internal injury risk

Correct Incorrect Correct answer

The seatbelt sign only indicates skin injury and does not suggest deeper tissue damage

Correct Incorrect Correct answer

Seatbelt injuries are limited to abdominal wall contusions that resolve without treatment

Correct Incorrect Correct answer

Which abdominal organ is most commonly injured in blunt abdominal trauma?

The spleen

Correct Incorrect Correct answer

The kidneys

Correct Incorrect Correct answer

The pancreas

Correct Incorrect Correct answer

The small intestine

Correct Incorrect Correct answer

What type of injury results from the primary blast wave (overpressure wave) in an explosion?

Injuries to air-filled organs including blast lung, tympanic membrane rupture, and bowel perforation

Correct Incorrect Correct answer

Penetrating injuries from flying debris and shrapnel

Correct Incorrect Correct answer

Blunt injuries from being thrown against objects by the blast wind

Correct Incorrect Correct answer

Thermal burns from the fireball and radiant heat

Correct Incorrect Correct answer

A victim of an explosion presents with bilateral hearing loss, hemoptysis, respiratory distress, and abdominal pain. SpO2 is 82% on high-flow oxygen. What is the primary concern regarding positive pressure ventilation in this patient?

Blast lung injury with alveolar damage increases the risk of air embolism and pneumothorax when positive pressure ventilation is applied

Correct Incorrect Correct answer

Positive pressure ventilation is safe and should be initiated immediately at high pressures

Correct Incorrect Correct answer

The hearing loss prevents the patient from cooperating with ventilation instructions

Correct Incorrect Correct answer

Abdominal distension will make ventilation uncomfortable but not dangerous

Correct Incorrect Correct answer

Multiple victims from a building explosion arrive at the casualty collection point. One patient who was initially standing and talking becomes suddenly unresponsive 20 minutes later. CT would likely reveal what injury?

Delayed presentation of blast-related traumatic brain injury or air embolism from blast lung, both known for causing sudden deterioration after initial lucidity

Correct Incorrect Correct answer

Simple concussion that self-resolves without intervention

Correct Incorrect Correct answer

Psychological response to the traumatic event causing dissociation

Correct Incorrect Correct answer

Dehydration from environmental exposure at the blast scene

Correct Incorrect Correct answer

In blast injury classification, what are secondary blast injuries?

Injuries caused by flying debris, shrapnel, and projectiles propelled by the blast

Correct Incorrect Correct answer

Injuries from the direct overpressure wave affecting air-filled organs

Correct Incorrect Correct answer

Injuries from the victim being thrown by the blast wind against objects

Correct Incorrect Correct answer

Injuries from structural collapse, fires, and environmental contamination

Correct Incorrect Correct answer

A paramedic is treating multiple blast victims in an outdoor explosion. One victim has bilateral tympanic membrane rupture. Beyond the ear injury itself, why is this finding clinically significant?

Tympanic membrane rupture indicates the patient was exposed to significant overpressure and should be assessed for occult primary blast injuries to the lungs and bowel

Correct Incorrect Correct answer

The ear injury requires immediate surgical repair before other injuries are addressed

Correct Incorrect Correct answer

Bilateral TM rupture means the patient cannot follow verbal commands, making treatment impossible

Correct Incorrect Correct answer

TM rupture is a minor injury with no correlation to other blast injury patterns

Correct Incorrect Correct answer

A patient near an explosion in an enclosed space presents with severe respiratory distress, hemoptysis, and subcutaneous emphysema across the chest. SpO2 is 78%. What combination of blast injuries is most likely?

Blast lung injury with pneumothorax, indicated by the hemoptysis, respiratory failure, and subcutaneous emphysema

Correct Incorrect Correct answer

Simple rib fractures causing pain-limited breathing

Correct Incorrect Correct answer

Smoke inhalation injury from the explosion

Correct Incorrect Correct answer

Cardiac contusion causing heart failure and pulmonary edema

Correct Incorrect Correct answer

Why are explosions in enclosed spaces more dangerous than those in open environments?

The blast overpressure wave reflects off walls and surfaces, amplifying the pressure and duration of exposure to victims inside

Correct Incorrect Correct answer

Enclosed spaces contain more oxygen, which increases the size of the fireball

Correct Incorrect Correct answer

Structural collapse is the only additional hazard in enclosed spaces

Correct Incorrect Correct answer

Enclosed spaces prevent victims from hearing the explosion, eliminating the protective startle reflex

Correct Incorrect Correct answer

A patient has a gunshot wound to the proximal thigh with arterial bleeding. A tourniquet is applied high and tight on the affected extremity, but blood continues to flow from the wound. What is the next step?

Apply a second tourniquet proximal to the first one, as a single tourniquet may not generate sufficient pressure to occlude arterial flow in the thigh

Correct Incorrect Correct answer

Remove the first tourniquet and reposition it directly over the wound

Correct Incorrect Correct answer

Release the tourniquet for 10 seconds to allow blood flow, then reapply

Correct Incorrect Correct answer

Abandon the tourniquet and switch to direct pressure only

Correct Incorrect Correct answer

A multisystem trauma patient has a GCS of 8, a suspected left tension pneumothorax, and bilateral femur fractures with significant hemorrhage. The patient is in Class III shock. In what order should the paramedic address these injuries?

Secure the airway (GCS 8), decompress the tension pneumothorax, then address hemorrhage control and fluid resuscitation simultaneously during rapid transport

Correct Incorrect Correct answer

Splint both femur fractures first, then address the airway and breathing

Correct Incorrect Correct answer

Start IV fluids before addressing the airway or pneumothorax

Correct Incorrect Correct answer

Focus exclusively on the tension pneumothorax and defer all other interventions until hospital arrival

Correct Incorrect Correct answer

What is the concept of permissive hypotension in trauma resuscitation, and to which patient population does it apply?

Targeting a systolic blood pressure of 80 to 90 mmHg during fluid resuscitation of hemorrhagic shock to prevent disruption of early clot formation; it applies to penetrating trauma patients without head injury

Correct Incorrect Correct answer

Withholding all IV fluids from trauma patients regardless of blood pressure

Correct Incorrect Correct answer

Allowing blood pressure to drop to zero before initiating resuscitation

Correct Incorrect Correct answer

Aggressively resuscitating to a systolic blood pressure above 120 mmHg in all trauma patients

Correct Incorrect Correct answer

What is the ‘platinum ten minutes’ concept in trauma care?

The target time for completing on-scene assessment, critical interventions, and initiating transport of a trauma patient, emphasizing that extended scene times worsen outcomes

Correct Incorrect Correct answer

The first ten minutes after hospital arrival when surgery must begin

Correct Incorrect Correct answer

The maximum time a tourniquet can remain in place before causing permanent damage

Correct Incorrect Correct answer

The recommended duration for performing CPR on a trauma arrest patient

Correct Incorrect Correct answer

A trauma patient with suspected internal hemorrhage is being resuscitated with IV normal saline. After 2 liters of crystalloid, the patient remains tachycardic (HR 130) and hypotensive (BP 78/50). According to current trauma resuscitation evidence, what does this response indicate?

The patient is a transient or non-responder to crystalloid, indicating ongoing hemorrhage that likely requires blood product transfusion and surgical intervention

Correct Incorrect Correct answer

The IV fluid is being administered too slowly and the rate should be increased

Correct Incorrect Correct answer

The patient needs a vasopressor infusion to support blood pressure

Correct Incorrect Correct answer

Two liters of crystalloid is insufficient; administer another 4 liters before reassessing

Correct Incorrect Correct answer

A patient with a stab wound to the chest develops Beck’s triad: muffled heart sounds, jugular venous distension, and hypotension. The paramedic suspects cardiac tamponade. What is the prehospital management priority?

Rapid transport to a trauma center for pericardiocentesis or thoracotomy, with IV fluid bolus to temporarily increase preload during transport

Correct Incorrect Correct answer

Perform needle decompression of both sides of the chest

Correct Incorrect Correct answer

Administer furosemide IV to reduce the fluid around the heart

Correct Incorrect Correct answer

Apply bilateral chest seals and place the patient on CPAP

Correct Incorrect Correct answer
