EFMB ACTUAL EXAM SCRIPT QUESTIONS
AND ANSWERS FULLY REVIEWED
MATERIAL
●● T/F: Computed Tomography scanning has been largely replaced by
cervical spine radiographic evaluation (CSRE) and should only be
performed when CSRE is unavailable.
Answer: False: CT has largely replaced CSRE and is the primary mode
of evaluation. CSRE is performed when CT is unavailable.
●● What is the lowest level of care equipped with a Computed
Tomography scanner?
Answer: role 3 and above
●● What is the lowest level of care equipped with a portable x-ray
machine?
Answer: Role 2; many portable units such as at the role 2 have limited
ability to penetrate soft tissues
●● Members of the trauma team should have _____ aprons and thyroid
shields available near the trauma bay for radiation safety.
Answer: lead; ideally dawning lead shielding beneath other PPE prior to
patient arrival
,●● Distance is also protective from radiation exposure. If feasible based
on the patient's condition, any personnel without lead shielding should
move a short distance away from the x-ray unit. The recommended
minimal distance is _____.
Answer: 6 feet away from x-ray unit
●● While the FAST scan has been validated only in hemodynamically
unstable blunt trauma patients, it has become a standard tool in the
trauma bay and Emergency Department (ED) in most trauma patients.
FAST stands for____________________.
Answer: Focused abdominal sonographic assessment for trauma
●● FAST in combat trauma has a sensitivity of only 56% and specificity
of ___.
Answer: 98%
●● T/F: The FAST exam remains the most sensitive test for hollow
viscus injury and mesenteric injury.
Answer: False: DPL (diagnostic peritoneal lavage) remains the most
sensitive test for hollow viscus injury and mesenteric injury
●● T/F: At the Role 3, properly trained providers including radiologists,
surgeons, and emergency physicians, can perform and interpret FAST
scans in the emergency department on a hand held portable device.
,Answer: True: to free up emergency providers/surgeons to either
perform other assessments/interventions/provide care
●● A FAST examination is performed with a portable hand-held
machine most commonly using a standard 3-7 MHz curved array
_______________ probe.
Answer: US; a phased array probe is also acceptable and occasionally
preferred if cardiac or pulmonary imaging is necessary.
●● The standard FAST examination is focused on evaluating for the
presence of ______________ in certain areas of the body.
Answer: free intraperitoneal fluid in:
1. the URQ b/w liver and kidney
2. the LUQ b/w spleen and kidney
3. the pelvis at the level of the bladder
4. an evaluation for cardiac activity and hemopericardium/tamponade
should also be performed by placing the probe in the subxiphoid location
and aiming towards pts L shoulder.
●● When performing a FAST examination on a patient, you inspect the
right upper quadrant. You are inspecting between which two organs?
Answer: b/w the liver and the kidney
, ●● When performing a FAST examination on a patient, you inspect the
left upper quadrant. You are inspecting between which two organs?
Answer: spleen and kidney
●● An 18g ______________ IV is typically desired for Computed
Tomography IV access.
Answer: 18g antecubital IV is typically desired - if placed on a medical
evacuation platform prior to arrival, the cannula must be thoroughly
rechecked/flushed to ensure function and avoid contrast extravasation.
More distal upper extremity IVs should typically not be used due to the
risk of extravasation and compartment syndrome.
●● T/F: The goal of Computed Tomography contrast injection is to
provide concurrent solid organ enhancement, arterial enhancement, and
pulmonary arterial.
Answer: true
●● T/F: When performing Computed Tomography scan on a Military
Working Dog, utilize a scanning protocol based on the adult settings to
include the doses of and rates of contrast administration.
Answer: false; Pediatric settings
Utilize a scanning protocol based on the pediatric settings to include the
doses of and rates of contrast administration. radiologists can perform if
necessary
