the acute management of combat trauma was extensively established during
Operation Enduring Freedom. - 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.
All trauma patients arriving at a Role __________ hospital will receive proper and
expeditious radiologic screening of injuries. - ANSWER>>3
Section 2: Aural Blast Injury Acoustic Trauma & Hearing Loss - ANSWER>>-
T/F: Patients exposed to hazardous noise are only at risk for aural trauma. -
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.
The symptoms of acoustic trauma are: - ANSWER>>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 __________. - ANSWER>>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). - ANSWER>>tympanic membrane (TM)
T/F: the smaller the size of the tympanic membrane perforation, the greater the
likelihood is of spontaneous closure. - ANSWER>>TRUE
The majority of tympanic membrane perforations that close spontaneously do so
within the first __________ after injury. - ANSWER>>8 weeks
, Acute management of intratemporal facial nerve injury is to provide objective
documentation of facial movement using the __________ grading scale. -
ANSWER>>House-Brackmann
T/F: For significant facial pareses/paralyses, early administration of steroids must
always be provided regardless of contraindications. - ANSWER>>FALSE. Early
administration of steroids should be provided if not contraindicated, and referral
for management by an otolaryngologist is indicated.
Which inner ear abnormalities may cause vertigo? - ANSWER>>1. Otic Capsule
Violating Temporal Bone Fractures
2. Secondary Infections of the Inner Ear or Vestibular Nerves
3. Trauma Induced Endolymphatic Hydrops
4. Activation of Subclinical Super Semicircular Canal Dehiscence
"OSTA"
All Service Members that develop symptoms consistent with noise trauma (acute
tinnitus, muffled hearing, fullness in the ear) should... - ANSWER>>...be educated
and directed to self-report for evaluation and possible treatment as soon as
practicable.
What is the best course of action if you find debris in the External Auditory Canal
(EAC) or in the middle ear (as seen through a TM perforation)? - ANSWER>>Treat
the patient with a fluoroquinolone and steroid containing topical antibiotic (e.g.,
four (4) drops of ciprofloxacin/dexamethasone or ofloxacin in the affected ear
three (3) times a day for seven (7) days. Do not irrigate the ear as it may provoke
pain and vertigo.
Hearing loss that persists __________ hours after acoustic trauma warrants a
hearing test or audiogram. - ANSWER>>72 hours
T/F: Vestibular trauma to the inner ear may manifest in vertigo. -
ANSWER>>TRUE
All patients with subjective hearing loss and tinnitus following blast exposure
