CAISS Study Guide Exam Questions and Answers
Updated (Verified Answers)
1. Origins of AIS (3)
ANS 1) Standardized system
2) Classify type/severity of injury from MVC
3) Consensus
2. Injury descriptors are organized
? ANS Anatomi- cally
3. Injur
y severity is ranked relative to its importance to
? ANS -
The whole body
4. AIS reflects severity of single injuries and are unaffected by what
three things
? ANS 1) time
2) sequela
3) outcome
,5. What type of scale does AIS use
? ANS 6 point ordinal scale
6. Which type of measurement is more variable? Anatomic or Physiologic
? ANS -
Physiologic
7. Is clinical training necessary for collecting injury data
? ANS NO
8. AIS is based on what three (3) factors
? ANS 1) anatomically- based
2) consensus driven
3) global
9. Severity is NOT contingent upon what two (2) factors
? ANS 1) Outcome
2) time
10.Is mortality a sole determinant of AIS severity
? ANS NO
11.Are all AIS data comparable from year to year
? ANS NO (updates)
, 12.Is "DEATH" part of the severity scale
? ANS NO
13.Is a patient who dies automatically assigned the highest AIS severity
of 6
? ANS NO (patients w/ minor injuries can die)
14.Does a linear relationship exist between AIS severity codes
? ANS NO (AIS 4 is more, NOT twice as severe as AIS 2)
15.Are all injuries within the same AIS code strictly compatible
? ANS NO (tibia fx & alveolar ridge are both AIS - 2, although one may
be worse than the other, both are considered 'moderate')
16.What AIS code is assigned to a patient with inadequate information
regard- ing an injury
? ANS 9
17.AIS single digit severity codes are based on what type of patient
? ANS Average
