Which of the following injuries CANNOT be effectively ruled out by the EFAST exam?
1 point
Intraperitoneal bleed
Cardiac tamponade
Hemothorax
Pneumothorax
Retroperitoneal bleed
Clear selection
What is the minimum amount of free fluid that can be identified by FAST exam in the pelvic view
1 point
150 mls
200 mls
250 mls
300 mls
400 mls
500 mls
Clear selection
In the RUQ and LUQ the image obtained is in which standard imaging plane?
1 point
transverse plane
coronal plane
saggital plane
longitudinal plane
Clear selection
You visualize a round fluid and air filled structure in the LUQ. What are you likely imaging?
1 point
The right colic flexure
Intraluminal contents and blood from a ruptured hollow viscous
The stomach
A splenic injury
Clear selection
Which is the following is FALSE regarding the RUQ FAST view?
1 point
Common pitfalls include mistaking the IVC and gallbladder for free fluid
The liver is an excellent acoustic window
You need less free fluid in Morison's pouch in the supine patient (as opposed in tredelenberg position) for it to be visualized on ultrasound
The RUQ view is in the coronal plane
Free fluid usually makes sharp angles on ultrasound
Clear selection
Which of the following is FALSE regarding the LUQ FAST view?
1 point
The spleen does not adhere to the diaphragm so free fluid is more likely to collect between the two than on the right side of the abdomen
The stomach can be mistaken for free fluid when scanning the LUQ
When performing FAST view on the LUQ, the probe must be aimed more posterior to avoid the stomach
When performing the FAST view on the LUQ, the probe must be positioned more caudal due to the lower kidney position on the left side
Clear selection
Which of the following is FALSE regarding the pelvic FAST view?
1 point
To best visualize free fluid, one only needs to perform the transverse view of the pelvis
The peritoneum is cephalad to the bladder and separates the abdominal cavity from the pelvis
The most common place for fluid to collect in the female is the posterior cul-de-sac (pouch of douglas)
Due to posterior acoustic enhancement when the bladder is fluid fluid, the gain should be decreased to avoid missing free fluid
A large amount of free fluid in the pelvis can be mistaken for the bladder
Clear selection
Pericardial fat pad is likely to broaden near the apex of the heart
1 point
true
false
Clear selection
The best positioning for the probe when evaluating for pneumothorax is to place the probe
1 point
On the most dependent portion of the chest
Just above the diaphragm on the lateral aspect of the best
Anterior chest, mid-clavicular line, just below the clavicle
Left and right parasternal area
Clear selection
Which of the following is FALSE regarding the cardiac FAST and pneumothorax view?
1 point
On the subxiphoid view, the anterior fat pad can be seen between the liver and heart
A true pericardial effusion/fluid should be present in more than one view of the heart
On the parasternal long view of the heart, free fluid is most likely to collect next to the right ventricle
If you see lung sliding and comet tails, there is not a pneumothorax present
A pericardial fluid collection should widen as it approaches the apex of the heart
Clear selection
What can mimic a pneumothorax?
1 point
Blebs
Lung scarring
Right mainstem intubation
All of the above
Clear selection
