QUESTIONS AND SOLUTIONS GRADED A+
✔✔mandible fractures - ✔✔-teeth no longer fit together properly or may be missing
-crepitus or step off
✔✔mid-face fracutres - ✔✔-face may appear asymmetrical or flattened
-inability to close mouth
-face pain and numbness
-crepitus
✔✔what are the 3 MOIs that you would consider spinal precautions for - ✔✔-MVC
-fall >15ft
-IED blast involving MRAP vehicle
✔✔if casualty if showing signs of increased ICP what rate should you ventilate them at -
✔✔20 bpm and SPO2 >90%
✔✔contraindication of NPA - ✔✔-Basilar skull fracture(s)
-Raccoon Eyes
-Battle Signs
-Maxillofacial trauma
-Exposed brain matter
-CSF draining from the nose, mouth, or ears
✔✔how to control hemorrhage for soft tissue injuries to head - ✔✔control significant
bleeding with pressure on the edges of the wound (donut gauze)
✔✔how to control hemorrhage for complex scalp injuries to head - ✔✔several gauze
pads held in place by an elastic roller bandage creates an effective pressure dressing to
control significant bleeding
✔✔when should pressure dressing not be used for head injuries - ✔✔do not apply
pressure dressings to open or depressed skull fractures
✔✔how to manage shock If the casualty has an altered mental status due to suspected
TBI *and* has weak or absent radial pulse? - ✔✔resuscitate as necessary to restore
and maintain a normal radial pulse
-target systolic BP of at least 90mmHg
✔✔what analgesics can worsen a moderate-sever TBI - ✔✔ketamine and OCTF
, ✔✔should morphine be administered to casualty with suspected TBI - ✔✔Due to
Morphine's effect on ICP and pupillary response, it is NOT recommended in patients
with a suspected brain injury
✔✔what can pupil reaction tell us (very important to know) - ✔✔-difference >1mm in
pupil size is abnormal
-sluggish or nonreactive pupil is abnormal
-both pupils dilated and not reactive to light indicates brainstem injury
-injury is reversible if pupils are dilated but react to light
-dilated pupils with normal LOC is not dur to head injury
✔✔how to transport a casualty with a TBI - ✔✔-supine
-facial wound present: tilt casualty towards side of injury to allow for drainage
-cerebral perfusion may be jeopardized when head is elevated > 30 degrees
✔✔cerebral perfusion may be jeopardized when head is elevated how far - ✔✔elevated
greater than 30 degrees
✔✔Cushing's triad - ✔✔-increased BP
-decreased BP
-irregular respiration rate
indicate increased ICP
✔✔mild traumatic brain injury (mTBI) - ✔✔concussion
-can occur even without being knocked out/losing consciousness
-can temporarily change the way the brain works
Common causes of TBI/ Concussion include:
-Blasts, Blow to the head
-Vehicle crashes
-Being near a blast- projectile
-Falls
✔✔3 levels of TBI - ✔✔mild, moderate, severe
✔✔signs/symptoms of TBI - ✔✔-a transient alteration in neurologic function
SYMPTOMS
-Headache, Nausea, Vomiting
-Dizziness/balance problems
-Fatigue
-Insomnia/sleep disturbances
-Drowsiness
-Sensitivity to light/noise Blurred vision
-Difficulty remembering/concentrating
