-Anatomically

Injury severity is ranked relative to its importance to _______________? -
(correct answer) -The whole body

AIS reflects severity of single injuries and are unaffected by what three
things? - (correct answer) -1) time

2) sequela

3) outcome

What type of scale does AIS use? - (correct answer) -6 point ordinal scale

Which type of measurement is more variable? Anatomic or Physiologic? -
(correct answer) -Physiologic

Is clinical training necessary for collecting injury data? - (correct answer) -
NO

based

2) consensus driven

3) global

2) time

,Numerical ranking of severity: 1 - (correct answer) -minor

Numerical ranking of severity: 2 - (correct answer) -moderate

Numerical ranking of severity: 3 - (correct answer) -serious

Numerical ranking of severity: 4 - (correct answer) -severe

Numerical ranking of severity: 5 - (correct answer) -critical

(updates)

(correct answer) -single digit after the decimal (right)

(T/F) The 6 digit pre-dot codes are unique and allow for more specificity
and accurate coding? - (correct answer) -TRUE

answer) -Type of anatomic structure (skeletal, solid organ)

The third/fourth digits in the pre-dot code correspond to what? - (correct
answer) -Specific anatomic structure (femur)

The fifth/sixth digits in the pre-dot code correspond to what? - (correct
answer) -Level of injury within the specific body region and anatomic

of the squares of highest AIS in each of 3 most severely injured ISS body
regions.

What are the six body regions used in the ISS? - (correct answer) -1) head
& neck

2) face
