A 6 month old infant, being held in her mothers arms, is ejected on impact from a vehicle
that is struck head on by an oncoming car traveling at 65kph. The infant arrives in the ED
with multiple facial injuries, is lethargic, and is in severe respiratoy distress. Respiratory
support is not effective using a bag mask device, and her oxygen saturation is falling.
Repeated attempts at orotracheal intubation are unsuccessful. the most appropriate
procedure to perform next is:
A. perform needle cricothyroidotomy with jet insufflation
B. Administer heliox and racemic epinephrine
C. Perform nasotracheal intubation
D. Perform surgical cricothyroidotomy
E. Repeat orotracheal intubation
Give this one a try later!
A. perform needle cricothyroidotomy with jet insufflation
,A contraindication to nasogastric intubation is the presence of a:
A. Gastric perforation
B. Diaphragmatic rupture
C. Open depressed skull fracture
D. Fracture of the cervical spine
E. Fracture of the cribiform plate
Give this one a try later!
E. Fracture of the cribiform plate
The physioclogic hypervolemia of pregnancy has clinical significance in the management
of the severely injured gravid woman by
A. Reducing the need for blood transfusion
B. Increasing the risk of pulmonary edema
C. Complicating the management of closed head injury
D. Increasing the volume of blood loss to produce shock/maternal hypotension
E. Reducing the volume of crystalloid required for resuscitation
Give this one a try later!

An 8-year-old girl is an unrestrained passenger in a vehicle struck from behind. In the ED,
her blood pressure is 80/60mmHg, heart rate is 80 beats per minute, and respiratory rate
is 16 breaths per minute. Her GCS score is 14. She complains that her legs feel "funny and
wont move right". However, her spine x-rays do not show a fracture or dislocation. A
spinal cord injury in this child:
A. Is most likely a central cord syndrome
B. Must be diagnosed by magnetic resonance imaging
C. Can be excluded by obtaining a CT-scan of the entire spine
D. May exist in the abscence of objective findings on x-ray studies
E. Is unlikely because of the incomplete calcification of the vertebral bodies.

Which one of the following brain stem reflexes is not assessed when assessing for brain

Which of the follow statements concerning intraosseous infusion is TRUE?
A. Only crystalloid solutions may be safely infused through the needle

D. Intraosseous infusion may be utilized indefinitely
E. Swelling in the soft tissues around the intraosseous site is not a reason to discontinue
infusion.
