What is a schema error? - ✔✔✔ ANSWER-Level 1: Format / schema* - any element that does not
conform to the "rules" of the XSD.

be legal XML. Some errors in this Level do not have a Rule ID - for example: illegal tag,
commingling of null values and actual data, out of range errors, etc.
Pediatric Trauma Score - ✔✔✔ ANSWER-The PTS was developed to reflect the children's vulnerability
to traumatic injury. It emphasizes the importance of the child's weight and airway. Several studies
have confirmed that the PTS is a valid tool in predicting mortality of a traumatically injured child.
Mortality is estimated at 9% with a PTS > 8, and at 100% with a PTS ≤ 0. There is a linear relationship
between the decrease in PTS and the mortality risk (i.e. the lower the PTS, the higher the mortality
risk). The minimal score is -6 and the maximum score is +12. Pediatric Trauma Score (PTS) +2 +1 -1
Weight > 20 kg (44 lbs.) 10-20 kg (22-44 lbs.) < 10 kg (22 lbs.) Airway Patent Maintainable
Unmaintainable Systolic B/P > 90 mm Hg 50-90 mm Hg < 50 mm Hg CNS Awake + LOC Unresponsive
Fractures None Closed or suspected Multiple closed or open Wounds None Minor Major, penetrating
or burns
Monteggia fracture - ✔✔✔ ANSWER-Facture of ulna with dislocation of proximal radius.
If you suspect terrorism, do you code terrorism? - ✔✔✔ ANSWER-False, only if confirmed. You would
code assault unless confirmed terrorism attack.

burn only and not the amputation, at this point it would be considered treatment.
