UPDATE
During debridement, extremity wounds should be extended _________.
Longitudinally
During debridement, truncal wounds should be extended _________.
Along langer's lines
Due to their heavy contamina=on and the diminished healing capacity, how
long should the closure of blast wounds be avoided a@er the injury occurs?
48 hours
Assurance of ________ and removal of all nonviable skin, fat, fascia, muscle,
and bone are essen=al to reduce the load of contamina=on and necro=c =ssue
prior to dressing applica=on.
Hemostasis
All methods of wound irriga=on are adjuncts and not subs=tutes to what?
Sharp surgical debridement
The current recommenda=on of irriga=on volume for small wounds is:
1 - 3 liters
The current recommenda=on of irriga=on volume for moderate wounds is:
4 - 8 liters
The current recommenda=on of irriga=on volume for large wounds or wounds
with evidence of heavy contamina=on is:
9 or more liters
,T/f: normal saline, sterile water and potable tap water all have comparable
efficacy and safety as irriga=on solu=ons.
True
T/f: the inclusion of irriga=on fluid addi=ves such as iodine, bacitracin or
an=bio=cs has proven benefits.
False
What are risk factors of invasive fungal infec=ons assessed for during the first
wound debridement?
Dismounted blast injury, above the knee amputa=on, extensive
perineal/genitourniary/rectal injury, massive transfusion of >20 units in the first
24 hours
T/f: all wounds must be closed prior to arrival at a defini=ve care loca=on to
prevent further bacterial and fungal introduc=on.
False
T/f: placement of an=bio=c impregnated polymethylmethacrylate (pmma) can
be used as an adjunct to debridement and irriga=on of a wound to deliver
increased local an=bio=c concentra=ons while minimizing the associated side
effects of high systemic loads of these an=bio=cs.
True
A(n) _________ event refers to an iatrogenic event in which a sponge or
surgical instrument is deliberately or uninten=onally le@ behind while the
wound proceeds to defini=ve management.
Retained foreign object (rfo)
Explosive muni=ons injure through how many major mechanisms?
Four
T/f: pa=ents exposed to hazardous noise are only at risk for aural trauma.
False
,The symptoms of acous=c trauma are:
Tinnitus, recruitment, aural fullness, difficulty localizing sounds, difficulty
hearing in a noisy background, and ver=go.
Acous=c trauma may result in sensorineural hearing loss (snhl) that is either
_____________or _____________.
Temporary (temporary threshold shi@) or permanent (permanent threshold
shi@).
The ear, specifically the _____________, is the most sensi=ve organ to primary
blast injury.
Tympanic membrane (tm)
T/f: the smaller the size of the tympanic membrane perfora=on, the greater the
likelihood is of spontaneous closure.
True
The majority of tympanic membrane perfora=ons that close spontaneously do
so within the first ___________ a@er injury
8 weeks
Acute management of intratemporal facial nerve injury is to provide objec=ve
documenta=on of facial movement using the _____________ scale.
House-brackmann
T/f: for significant facial pareses/paralyses, early administra=on of steroids
must always be provided regardless of contraindica=ons.
False
All service members that develop symptoms consistent with noise trauma
(acute =nnitus, muffled hearing, fullness in the ear) should:
Educated and directed to self-report for evalua=on and possible treatment as
soon as is prac=cable.
, What is the best course of ac=on if you find debris in the external auditory
canal or in the middle ear?
Treat the pa=ent with a fluoroquinolone and steroid containing topical
an=bio=c.
Hearing loss that persists ___ hours a@er acous=c trauma warrants a hearing
test or audiogram
72 hours
T/f: ves=bular trauma to the inner ear may manifest in ver=go.
True
All pa=ents with subjec=ve hearing loss and =nnitus following blast exposure
should:
Have the exposure documented and be evaluated by hearing test as soon as
possible.
Pa=ents with as greater than ______ losses in three consecu=ve frequencies
should be considered candidates for high dose oral and/or transtympanic
steroid injec=ons when not otherwise contraindicated.
25 db
The ini=al radiographic evalua=on of a trauma pa=ent begins with supine
anteriorposterior (ap) chest and pelvis radiographs taken in the trauma bay
usually with a(n) _________________.
Portable x-ray machine

radiographic evalua=on (csre) and should only be performed when csre is
unavailable.
False
What is the lowest level of care equipped with a computed tomography
scanner?
