  • 1. 
    Which   of   the   following   is   true   regarding   neurogenic   shock?
    • A. 

      First-line   therapy   consists   of   repetitive   fluid   boluses   with   crystalloids.

    • B. 

      Pure   α-adrenergic   sympathomimetics   are   the   vasopressor   drugs   of   choice.

    • C. 

      Tachycardia   and   hypotension   are   pathognomonic   signs   of   neurogenic   shock.

    • D. 

      The   absence   of   a   cervical   collar   can   be   used   to   rule   out   neurogenic   shock.

    • E. 

      Dopamine   is   the   preferred   vasopressor   agent.

  • 2. 
    Which   of   the   following   is   true   regarding   the   management   of   elevated   ICP?
    • A. 

      Hemicraniectomy   is   first-line   therapy   for   elevated   ICP.

    • B. 

      Hypertonic   saline   is   superior   to   mannitol   for   osmotherapy

    • C. 

      Prolonged   hyperventilation   is   a   benign   method   for   lowering   elevated   ICP.

    • D. 

      Maintenance   of   elevated   cerebral   perfusion   pressure   (CPP)   may   be   more   important   in   improved   neurologic   outcome   at   the   expense   of   high   ICP.

    • E. 

      Persistent   hyperventilation   is   a   terrific   method   to   sustain   alkalization   and   combat   acidosis   in   the   brain   for   long   periods.

  • 3. 
    Which   of   the   following   statements   regarding   the   evaluation   and   care   of   head-injured   patients   is   the   most   accurate?
    • A. 

      Hypotension   is   often   the   direct   result   of   intracranial   trauma.

    • B. 

      Decerebrate   posturing   is   a   common   response   to   diffuse   cortical   injury.

    • C. 

      A   score   of   5   on   the   GCS   is   associated   with   a   poor   prognosis.

    • D. 

      The   syndrome   of   inappropriate   antidiuretic   hormone   secretion   (SIADH)   should   be   suspected   when   the   serum   sodium   level   exceeds   150 mEq/L.

    • E. 

      Brain   injury   takes   predominance   over   any   other   injury,   and   therefore   initial   evaluation   and   management   should   focus   only   on   the   neurologic   examination.

  • 4. 
    Which of the following statements regarding cerebral edema caused by head injury is the most accurate?
    • A. 

      CT   should   be   performed   to   exclude   the   diagnosis   of   intracranial   hemorrhage   or   a   mass   lesion   before   starting   therapy

    • B. 

      Cerebral   edema   caused   by   head   injury   is   vasogenic   and   not   cytotoxic   in   origin.

    • C. 

      Steroids   are   useful   for   the   treatment   of   head   trauma.

    • D. 

      Hypercapnia   induces   cerebral   vasoconstriction   and   is   useful   for   decreasing   intracerebral   blood   volume.

    • E. 

      Within   a   few   hours   (1   to   3   hours)   after   injury,   maximal   cerebral   edema   has   already   formed,   so   further   monitoring   is   unnecessary   if   the   patient   is   clinically   stable.

  • 5. 
    Which   of   the   following   statements   regarding   traumatic   CSF   leaks   is   false?
    • A. 

      Most   are   caused   by   basilar   skull   fractures   and   close   spontaneously.

    • B. 

      The   risk   for   infection   is   greater   with   rhinorrhea   than   with   otorrhea.

    • C. 

      They   often   do   not   require   immediate   surgical   repair   to   avert   infection.

    • D. 

      They   may   be   observed   for   up   to   14   days   if   there   is   no   evidence   of   infection.

    • E. 

      The   presence   of   a   traumatic   CSF   leak   mandates   the   use   of   prophylactic   broad-spectrum   antibiotic   coverage.
