Section 1: Initial Assessment & Airway Management
Question 1
A 34-year-old male arrives at the trauma bay following a high-speed motor vehicle collision. He
is comatose, has gurgling respirations, and exhibits vomitus in his oropharynx. After opening his
airway using a jaw-thrust maneuver and providing supplemental oxygen, what is the most
appropriate next step?
• A. Perform immediate endotracheal intubation.
• B. Insert a nasopharyngeal airway.
• C. Suction the oropharynx thoroughly.
• D. Perform a needle cricothyroidotomy.
Correct Answer: C. Suction the oropharynx thoroughly.
Rationale:
Airway maintenance with cervical spine protection is the first priority of the Primary Survey.
Gurgling indicates fluid or debris (such as blood or vomitus) in the upper airway, posing an
,immediate risk of aspiration and airway obstruction. Before attempt at advanced airway
placement or insertion of adjuncts, the airway must be cleared by suctioning under direct vision.
Question 2
A 6-month-old infant is brought to the emergency department after being involved in a severe car
crash. The infant is lethargic with severe facial trauma and agonal breathing. Bag-mask
ventilation is ineffective due to altered facial anatomy, and two attempts at orotracheal intubation
have failed. What is the definitive next step for securing an airway?
• A. Perform surgical cricothyroidotomy.
• B. Perform needle cricothyroidotomy with jet insufflation.
• C. Attempt nasotracheal intubation.
• D. Insert a laryngeal mask airway (LMA) and re-evaluate.
Correct Answer: B. Perform needle cricothyroidotomy with jet insufflation.
Rationale:
In infants and children under 12 years of age, surgical cricothyroidotomy is relatively
contraindicated due to the small size of the cricothyroid membrane and the high risk of damage
to the cricoid cartilage (which is the only complete cartilaginous ring in the trachea). When
standard non-invasive measures and orotracheal intubation fail in infants, a needle
cricothyroidotomy with percutaneous jet insufflation is the preferred emergency surgical airway
to provide temporary oxygenation until a formal tracheostomy can be performed in the operating
room.
Question 3
According to ATLS 10th Edition guidelines, which of the following is the anatomical landmark
for needle decompression of a tension pneumothorax in an adult patient?
• A. 2nd intercostal space in the midclavicular line.
• B. 5th intercostal space in the anterior-to-midaxillary line.
• C. 3rd intercostal space in the midaxillary line.
• D. 4th intercostal space in the parasternal line.
Correct Answer: B. 5th intercostal space in the anterior-to-midaxillary line.
Rationale:
The 10th Edition updated the primary recommended site for needle thoracocentesis in adult
trauma patients from the 2nd intercostal space midclavicular line to the 5th intercostal space in
, the anterior-to-midaxillary line (at the same level as chest tube insertion). Studies demonstrated
that chest wall thickness at the 2nd intercostal space frequently exceeds standard angiocatheter
length, leading to failure rates, whereas the 5th intercostal space anterior-to-midaxillary line
provides a higher success rate. (Note: In pediatric patients, the 2nd intercostal space MCL
remains acceptable).
Section 2: Shock & Fluid Resuscitation
Question 4
A 28-year-old male arrives in hemorrhagic shock following a gunshot wound to the abdomen.
His skin is cool and clammy, his pulse rate is 135 bpm, and his blood pressure is 78/50 mmHg.
According to ATLS 10th Edition guidelines, what is the initial recommended volume bolus of
warmed isotonic crystalloid solution for an adult patient?
• A. 2,000 mL
• B. 1,000 mL
• C. 500 mL
• D. 250 mL
Correct Answer: B. 1,000 mL
Rationale:
A major update in the ATLS 10th Edition is the reduction of the initial fluid bolus from 2 liters to
1 liter of warmed isotonic crystalloid solution (e.g., Lactated Ringer's) for adults. Aggressive
fluid administration prior to surgical control of hemorrhage exacerbates dilutional coagulopathy,
disrupts early clot formation, and increases mortality. If the patient remains hemodynamically
unstable after the 1 L bolus, early administration of blood products (packed red blood cells,
plasma, and platelets in a 1:1:1 ratio) should be initiated immediately.
Question 5
A severely injured trauma patient receives multiple units of uncrossmatched blood. Tranexamic
acid (TXA) is ordered. To achieve maximal reduction in mortality, within what time window
from the initial injury must TXA be administered?
• A. Within 1 hour.
• B. Within 3 hours.
• C. Within 6 hours.
• D. Within 12 hours.
Correct Answer: B. Within 3 hours.
