QUESTIONS WITH VERIFIED ANSWERS || GRADED A+
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
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 ANSWER -False; CSRE has been largely
replaced by CT scan
What is the lowest level of care equipped with a Computed Tomography
scanner? - CORRECT ANSWER -Role 3
T/F: 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
T/F: At the Role 3, properly trained providers including radiologists, surgeons,
andemergency physicians, can perform and interpret FAST scans in the
emergencydepartment on a hand held portable device. - CORRECT ANSWER
-True
A FAST examination is performed with a portable hand-held machine
mostcommonly using a standard 3-7 MHz curved array _______________
probe. - CORRECT ANSWER -US
,The standard FAST examination is focused on evaluating for the presence
of______________ in certain areas of the body. - CORRECT ANSWER -
intraperitoneal fluid
When performing a FAST examination on a patient, you inspect the right upper
quadrant. You are inspecting between which two organs? - CORRECT
ANSWER -liver and kidney
When performing a FAST examination on a patient, you inspect the left
upperquadrant. You are inspecting between which two organs? - CORRECT
ANSWER -Spleen and kidney
An 18g ______________ IV is typically desired for Computed Tomography IV
access. - CORRECT ANSWER -antecubital
T/F: The goal of Computed Tomography contrast injection is to provide
concurrentsolid organ enhancement, arterial enhancement, and pulmonary
arterial. - CORRECT ANSWER -True
What is the lowest level of care equipped with a portable x-ray machine? -
CORRECT ANSWER -Role 2
Members of the trauma team should have _____ aprons and thyroid shields
available near the trauma bay for radiation safety. - CORRECT ANSWER -
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
_____. - CORRECT ANSWER -6 feet
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 ANSWER -Focused Abdominal
Sonographic Assessment for Trauma
FAST in combat trauma has a sensitivity of only 56% and specificity of ___. -
CORRECT ANSWER -98%
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 ratesof contrast administration. - CORRECT ANSWER -False
(pediatric)
T/F: All patients evacuated through casualty evacuation should have images
sentelectronically ahead of time as well as have a CD created to send with the
patient as abackup. - CORRECT ANSWER -True
T/F: Magnetic Resonance Imaging is widely used in theater, as its utility in the
acutemanagement of combat trauma was extensively establishment during
OperationEnduring Freedom. - CORRECT ANSWER -False
All trauma patients arriving at a Role ___ will receive proper and
expeditiousradiologic screening of injuries. - CORRECT ANSWER -Role 3
T/F: Patients exposed to hazardous noise are only at risk for aural trauma. -
CORRECT ANSWER -False (only at risk for acoustic trauma)
The symptoms of acoustic trauma are: - CORRECT ANSWER -hearing loss,
tinnitus, aural fullness, recruitment, difficulty
localizing sounds, difficulty hearing background, and vertigo
Acoustic trauma may result in sensorineural hearing loss (SNHL) that is
either_____________or _____________. - CORRECT ANSWER -temporary
or permanent
, The ear, specifically the _____________, is the most sensitive organ to primary
blastinjury. - CORRECT ANSWER -tympanic membrane (TM)
T/F: The smaller the size of the tympanic membrane perforation, the greater
thelikelihood is of spontaneous closure. - CORRECT ANSWER -True
The majority of tympanic membrane perforations that close spontaneously do
sowithin the first ___________ after injury. - CORRECT ANSWER -8 weeks
Acute management of intratemporal facial nerve injury is to provide
objectivedocumentation of facial movement using the _____________ scale. -
CORRECT ANSWER -House-Brackmann grading scale
T/F: For significant facial pareses/paralyses, early administration of steroids
must always be provided regardless of contraindications. - CORRECT
ANSWER -False; if not contraindicated
Which inner ear abnormalities may cause vertigo? - CORRECT ANSWER -
benign paroxysmal positional vertigo (BPPV), damage to sensitive
neuroepthileial rests, perilymphatic
fistula, otic capsule violating temporal bone fractures, secondary infections of
the inner ear or vestibular
nerves, trauma induced endolymphatic hyrops, and activation of subclincical
superior semicircular canal
dehiscence
All Service Members that develop symptoms consistent with noise trauma
(acutetinnitus, muffled hearing, fullness in the ear) should: - CORRECT
ANSWER -Be educated and directed to self-report for evaluation and possible
treatment as
soon as practical.
