CAISS CERTIFICATION STUDY TEST
QUESTIONS WITH CORRECT ANSWERS
2024-2025
Origins of AIS (3) - ANSWER 1) Standardized system 2) Classify injury
type/severity from a motor vehicle accident
3) Consensus
How are the injury descriptors organized? - Answer anatomically.
Injury severity is ranked about its importance to _______________. - ANSWER
The entire body
AIS reflects the severity of individual injuries and is unaffected by which three
factors? - Answer 1) time.
2) sequela.
3) result.
What kind of scale does AIS use? - ANSWER 6 point ordinal scale.
Which kind of measuring is most variable? Anatomic or physiological? -
ANSWER Physiologic
Is clinical training required for collecting injury data? - The answer is NO.
What three (3) factors form the basis of AIS? - ANSWER 1) Anatomically
grounded.
2) consensus-driven.
,3) Global.
What are the two (2) things that do not affect severity? - ANSWER 1) The outcome
2) time
Severity is ranked numerically as follows: 1 = minor.
Numerical ranking of severity: 2 - ANSWER Moderate
Severity is ranked numerically as 3 (answer: serious).
Severity is ranked numerically as follows: 4 - severe.
Numerical ranking of severity: 5 - ANSWER critical.
Numerical severity ranking: 6 - ANSWER maximum (now untreatable).
Is death the only factor of AIS severity? - The answer is NO.
Is all AIS data comparable from year to year? - ANSWER NO (updated)
Is "DEATH" on the severity scale? - The answer is NO.
Is a patient who dies automatically assigned the highest AIS severity, 6? -
ANSWER NO (people with slight injuries may die).
,Is there a linear relationship between AIS severity codes? - NO, AIS 4 is not twice
as severe as AIS 2.
Are all injuries with the same AIS code strictly compatible? - ANSWER NO (tibia
fx and alveolar ridge are both AIS - 2, and while one may be worse than the other,
both are considered moderate)
What AIS code is assigned to a patient who has insufficient information on an
injury? - ANSWER 9.
What type of patient is the basis for the AIS single-digit severity codes? - Answer
Average
What four characteristics constitute the "average" patient? - ANSWER 1) 25-40
years old.
2) No pre-existing conditions.
3) No tx problems.
4) received prompt and proper care.
Approximately how many injury descriptors are present in AIS? - Answer 2000.
What section of the AIS code is known as the "Pre-Dot Code?" - ANSWER: Six
digits before the decimal point (left)
What element of the AIS code constitutes the "AIS Severity Number?" -
ANSWER: single digit after decimal (right)
(T/F) The six-digit pre-dot codes are unique and allow for more specific and
accurate coding. - The answer is true.
, What does the first digit in the pre-dot code stand for? - ANSWER Body Region.
What does the second digit in the pre-dot code stand for? - ANSWER Type of
anatomic structure (skeletal or solid organ)
What do the third and fourth digits of the pre-dot code correspond to? - ANSWER
Specific anatomical structure (femur).
What do the fifth and sixth digits of the pre-dot code correspond to? - ANSWER
Level of injury within the relevant bodily region and anatomical structure (NFS,
minor, major)
What does the AIS dictionary's parenthesis indicate? - Provide synonyms or
definitions for injury types.
What do brackets in the AIS dictionary indicate? - ANSWER
inclusionary/exclusionary information and OIS grades
What does boxed bold type in the AIS dictionary indicate? • ANSWER instructions
to assist the coder choose acceptable code
What do semicolons in the AIS dictionary indicate? - ANSWER: Separate injury
descriptors with equivalent severity
