shows signs of subcutaneous emphysema, is dyspneic, and complains of
abdominal pain. In the ED, bilateral chest rubes are inserted and decompress
the pneumothoraces; however, he remains tachycardia and hypotensive. The
most likely etiology is:.
Answer: intraabdominal hemorrhage
◍ A previously healthy 70kg man suffered ~2L of acute blood loss. Which
appropriately applies to this patient?.
Answer: His systolic BP will be decreased with a narrowed pulse
pressureNOT his pulse pressure will be widened, urinary output at lower
level of normal, tachy but no BP change, or maintained systolic BP with
elevated diastolic BP
◍ Middle meningeal artery.
Answer: MC artery lacerated in epidural hematoma
◍ A 56-year-old male archer was riding a horse when it bucked and the saddle
struck him in the chest wall. You note paradoxical chest wall movement on
the left anterior chest. CXR is negative..
Answer: Flail chest due to costochondral disruption
◍ Blood Alcohol Concentration.
Answer: Level indicating potential impairment or injury risk.
◍ Increase fluids to target urine output of 100 cc/hr (theoretically washing out
myoglobin before it can settle in), Mannitol (acts a free radical scavenger,
and osmo diuretic to increase urine output and wash out myoglobin).

◍ A 22-year-old female presents after jumping from the 3rd story of a building
in a suicide attempt. She's stable, but GCS is 13. Both ankles are swollen.
Her pulses intact. Initial chest and pelvis films are normal. Ankle films
reveal bilateral calcanea fracture. What additional work-ip is important to
undertake in this patient?.

Answer: underlying lung contusion
◍ 14yo M is injured with a propane tank explosion and he is thrown 5m (16ft)
against a tree. He arrives in the ED with a BP of 80/45, HR 100, RR of 32.

are not burned. He is gasping and says that he cannot breathe. His neck
veins are distended. Most likely cause of hypotension is?.
Answer: tension pneumothorax
◍ Ventilation, Hypercarbia.
Answer: For peds patients, a needle cricothyroidotomy is an appropriate
temporizing technique for oxygen, but does NOT provide adequate _______
, resulting in progressive ______

from the injury).

are coming from the wound. What are the associated
injuries:-Pneumothorax-Massive hemothorax-Open
pneumothorax-Diaphragm injury
◍ Signs of hemothorax.
Answer: Absence of breath sounds and dullness to percussion.

restrained and MOI

normal patient with suspected blunt abdominal injury?.
