hypothermia, electrical injury, whole body injury and burns are assigned to what
region?

body regions or a single AIS .6 injury. - ANS>> T
Should patients with a AIS .9 code be included in research studies? - ANS>> No
, Underestimation of the ISS score - ANS>> Assigning injuries to too few body
regions can result in what?

nerve weakness/paresis or subtotal loss of function? - ANS>> T
(T/F) AIS allows coding of cranial nerve "laceration" if there is documented
cranial nerve paralysis, or total loss of function? - ANS>> T
(T/F) Coding a basilar skull fracture based on physical signs or manifestations is
only permitted if there is evidence of traumatic head injury or the physical
manifestations cannot be related to a peripheral or facial injury (e.g., facial
fractures)? - ANS>> T
(T/F) Complications are coded as injuries? - ANS>> F
(T/F) Do not assume that a specific injury has occurred simply because a particular
outcome occurred. - ANS>> T
(T/F) Death is an automatic AIS .6. - ANS>> F
(T/F) An AIS of .1 can result in death. - ANS>> T
(T/F) Vertebral fractures and contusions are coded separately. - ANS>> F

in the Whole Area section of the dictionary chapter and assigned to the External
ISS body region. - ANS>> T
(T/F) In penetrating injuries, you should code the overlying skin injury, not just the
organ injury. - ANS>> F
