ACTUAL QUESTIONS AND CORRECT
ANSWERS
Section 1 - Radiology: Imaging Trauma Patients in a Deployed Setting -
CORRECT ANSWERS -
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 ANSWERS portable x-ray
machine
T/F: Computed Tomography scanning has been largely replaced by Cervical
Spine Radiographic Evaluation (CSRE) and should only be performed when
CSRE is unavailable. - CORRECT ANSWERS FALSE. Cervical Spine
Radiographic Evaluation (CSRE) has been largely replaced by Computed
Tomography (CT) and should only be performed when a CT is unavailable.
What is the lowest level of care equipped with a Computed Tomography (CT)
Scanner? - CORRECT ANSWERS Role 3
What is the lowest level of care equipped with a portable x-ray machine? -
CORRECT ANSWERS Role 2
Members of the trauma team should have __________ aprons and thyroid
shields available near the trauma bay for radiation safety. - CORRECT
ANSWERS lead
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 ANSWERS Six (6)
,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
__________. - CORRECT ANSWERS Focused Abdominal Sonographic
Assessment for Trauma
FAST in combat trauma has a sensitivity of only 56% and and specificity of
__________. - CORRECT ANSWERS 98%
T/F: The FAST exam remains the most sensitive test for hollow viscus injury
and mesenteric injury. - CORRECT ANSWERS FALSE. Diagnostic
Peritoneal Lavage (DPL) 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 US device. - CORRECT
ANSWERS TRUE
A FAST examination is performed with a portable hand-held machine most
commonly using a standard 3-7 MHz curved array __________ probe. -
CORRECT ANSWERS Ultra Sound (US)
The standard FAST examination is focused on evaluating for the presence of
__________ in certain areas of the body. - CORRECT ANSWERS Free
Intraperitoneal Fluid
When performing a FAST examination on a patient, you inspect the right upper
quadrant. You are inspecting between which two (2) organs? - CORRECT
ANSWERS Liver & Kidney
,When performing a FAST examination on a patient, you inspect the left upper
quadrant. You are inspecting between which two (2) organs? - CORRECT
ANSWERS Spleen & Kidney
An 18g __________ IV is typically desired for Computed Tomography IV
access. - CORRECT ANSWERS antecubital
T/F: The goal of Computed Tomography (CT) contrast injection is to provide
concurrent solid organ enhancement, arterial enhancement, and pulmonary
arterial. - CORRECT ANSWERS TRUE
T/F: When performing Computed Tomography (CT) 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. - CORRECT ANSWERS FALSE.
Utilize a scanning protocol based on the pediatric settings to include the doses
of and rates of contrast administration.
T/F: 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 ANSWERS TRUE
T/F: 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 ANSWERS 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.
All trauma patients arriving at a Role __________ hospital will receive proper
and expeditious radiologic screening of injuries. - CORRECT ANSWERS
3
, Section 2: Aural Blast Injury Acoustic Trauma & Hearing Loss - CORRECT
ANSWERS -
T/F: Patients exposed to hazardous noise are only at risk for aural trauma. -
CORRECT ANSWERS 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.
The symptoms of acoustic trauma are: - CORRECT ANSWERS 1.
Hearing Loss
2. Tinnitus (Ringing in the Ear)
3. Aural Fullness
4. Recruitment (Ear Pain with Loud Noise)
5. Difficulty Localizing Sounds
6. Difficulty Hearing in a Noisy Background
7. Vertigo
"H-TARDD-V"
Acoustic trauma may result in sensorineural hearing loss (SNHL) that is either
__________ or __________. - CORRECT ANSWERS temporary
(temporary threshold shift, TTS) or permanent (permanent threshold shift, PTS)
The ear, specifically the __________, is the most sensitive organ to primary
blast injury (PBI). - CORRECT ANSWERS tympanic membrane (TM)
T/F: the smaller the size of the tympanic membrane perforation, the greater the
likelihood is of spontaneous closure. - CORRECT ANSWERS TRUE
