,1. Section 1 - Radiology✔✔ CORRECT ANSWER Imaging Trauma Patients in a Deployed Setting✔✔ CORRECT
ANSWER -
2. The initial radiographic evaluation of a trauma patient begins with supine Anterior-Posterior (AP) chest and
pelvis radiographs taken in the trauma bay usually with a(n) .✔✔ CORRECT ANSWER portable x-ray machine
3. T/F✔✔ CORRECT ANSWER Computed Tomography scanning has been largely replaced by Cervical Spine
Radiographic Evaluation (CSRE) and should only be performed when CSRE is unavailable.✔✔ CORRECT ANSWER FALSE.
Cervical Spine Radiographic Evaluation (CSRE) has been largely replaced by Computed Tomography (CT) and should only be performed when a CT is unavailable.
4. What is the lowest level of care equipped with a Computed Tomography (CT) Scanner?✔✔ CORRECT
ANSWER Role 3
5. What is the lowest level of care equipped with a portable x-ray machine?✔✔ CORRECT ANSWER Role 2
6. Members of the trauma team should have aprons and thyroid shields
available near the trauma bay for radiation safety.✔✔ CORRECT ANSWER lead
7. 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
feet.✔✔ CORRECT ANSWER Six (6)
8. While the FAST scan has been validated only in hemodynamically unsta- ble blunt trauma patients, it has
become a standard tool in the trauma bay and Emergency Department (ED) in most trauma patients. FAST
stands for
.✔✔ CORRECT ANSWER Focused Abdominal Sonographic Assessment for Trauma
9. FAST in combat trauma has a sensitivity of only 56% and and specificity of
.✔✔ CORRECT ANSWER 98%
10. T/F✔✔ CORRECT ANSWER The FAST exam remains the most sensitive test for hollow viscus injury and
mesenteric injury.✔✔ CORRECT ANSWER FALSE. Diagnostic Peritoneal Lavage (DPL) remains the most sensitive test for hollow viscus injury and mesenteric
injury.
11. T/F✔✔ CORRECT ANSWER At the Role 3, properly trained providers including radiologists, sur- geons,
and emergency physicians, can perform and interpret FAST scans in the emergency department on a hand held
portable US device.✔✔ CORRECT ANSWER TRUE
,12. A FAST examination is performed with a portable hand-held machine most commonly using a standard 3-7
MHz curved array probe.✔✔ CORRECT
ANSWER Ultra Sound (US)
13. The standard FAST examination is focused on evaluating for the presence of in certain areas of the body.✔✔
CORRECT ANSWER Free Intraperitoneal Fluid
14. When performing a FAST examination on a patient, you inspect the right upper quadrant. You are inspecting
between which two (2) organs?✔✔ CORRECT ANSWER Liver & Kidney
15. When performing a FAST examination on a patient, you inspect the left upper quadrant. You are inspecting between
which two (2) organs?✔✔ CORRECT ANSWER Spleen & Kidney
16. An 18g IV is typically desired for Computed Tomography IV access.-
✔✔ CORRECT ANSWER antecubital
17. T/F✔✔ CORRECT ANSWER The goal of Computed Tomography (CT) contrast injection is to provide
concurrent solid organ enhancement, arterial enhancement, and pulmonary arterial.✔✔ CORRECT ANSWER
TRUE
18. T/F✔✔ CORRECT ANSWER When performing Computed Tomography (CT) scan on a Military Work- ing Dog
utilize a scanning protocol based on the adult settings to include the doses of and rates of contrast administration.✔✔
CORRECT ANSWER FALSE. Utilize a scanning protocol based on the pediatric settings to include the doses of and rates of contrast administration.
19. T/F✔✔ CORRECT ANSWER All patients evacuated through casualty evacuation should have images sent
electronically ahead of time as well as have a CD created to send with the patient as a backup.✔✔ CORRECT
ANSWER TRUE
20. T/F✔✔ CORRECT ANSWER Magnetic Resonance Imaging (MRI) is widely used in theater, as its utility in
the acute management of combat trauma was extensively established during Operation Enduring Freedom.✔✔ CORRECT
ANSWER FALSE. While Magnetic Resonance Imaging (MRI) has been deployed to theater in the past, its utility in the acute management of combat trauma
has not been established.
21. All trauma patients arriving at a Role hospital will receive proper and
expeditious radiologic screening of injuries.✔✔ CORRECT ANSWER 3
22. Section 2✔✔ CORRECT ANSWER Aural Blast Injury Acoustic Trauma & Hearing Loss✔✔ CORRECT
ANSWER -
, 23. T/F✔✔ CORRECT ANSWER Patients exposed to hazardous noise are only at risk for aural trauma.✔✔ CORRECT
ANSWER - FALSE. Service Members exposed to hazardous noise is impact noise or noise greater than 140 dB are at high risk for acoustic trauma and subsequent hearing
loss. Patients exposed to blasts are at risk for both aural and acoustic trauma.
