HL7 v2 Practice Exam Flashcards
The original mode acknowledgment protocol is equivalent to the enhanced acknowledgment protocol with which of the following field values?
A) Just the MSH-15-accept acknowledgment type equal to “AL”, the MSH-16-application acknowledgment type doesn’t matter.
B) Just the MSH-16-application acknowledgment type equal to “AL”, the MSH-15-accept acknowledgment type doesn’t matter.
C) The MSH-15-accept acknowledgment type equal to “NE” and the MSH-16-application acknowledgment type equal to “AL”.
D) The MSH-15-accept acknowledgment type equal to “AL” and the MSH-16-application acknowledgment type equal to “NE”.
E) The MSH-15-accept acknowledgment type equal to “NE”, the MSH-16-application acknowledgment type doesn’t matter.
C) The MSH-15-accept acknowledgment type equal to “NE” and the MSH-16-application acknowledgment type equal to “AL”.
NOTE: The Original Acknowledgment Protocol is equivalent to the Enhanced Acknowledgment Propocol with MSH-15 AcceptAckType = “NE” (Never) and MSH-16 ApplicationAckType = “AL” (Always). Never requires an Accept ACK and always requires an Application ACK. (pg56)

C) A subcomponent that is present but null is represented by including no characters in the subcomponent.
