✍️ Sample ATLS Questions & Answers

1. Which medication combination is most commonly used for rapid sequence intubation in the trauma setting?
Etomidate and succinylcholine

Etomidate provides rapid onset sedation with minimal hemodynamic effects, and succinylcholine provides rapid-onset, short-duration paralysis.

2. In massive transfusion protocol, what is the recommended PRBC:FFP:Platelets ratio?
1:1:1

A balanced 1:1:1 ratio mimics whole blood and prevents dilutional coagulopathy.

3. What point-of-care test does the 10th edition emphasize for guiding resuscitation?
Point-of-care lactate and base deficit

POC lactate and base deficit are objective metabolic markers that guide resuscitation more reliably than vital signs.

4. A blast injury victim presents with tympanic membrane rupture, pulmonary contusions, and bowel injury. Which mechanism causes bowel injury in blast victims?
Primary blast injury — overpressure wave disrupting air-fluid interfaces in hollow viscera

Primary blast injury results from the high-pressure shock wave acting on air-filled organs (lungs, bowel, middle ear) at tissue-air interfaces, causing barotrauma.

5. A 25-year-old with a left chest stab wound develops PEA in the trauma bay. What is the most appropriate intervention?
Emergency department thoracotomy

PEA from penetrating thoracic trauma is an indication for ED thoracotomy.

6. Which finding on examination of an eye injury warrants immediate ophthalmology consultation for possible open globe?
Teardrop-shaped pupil

A teardrop-shaped or peaked pupil suggests iris prolapse through a scleral or corneal laceration, indicating an open globe injury.
