"A group or question item from the original questionnaire for which answers are provided." - HL7 FHIR, QuestionnaireResponse.item
Note that in FHIR, this construct appears to duplicate the Item construct in the Questionnaire resource (in FHIM called the QuestionnaireItem), apparently in order to convey a minimal amount of information for when the QuestionnaireItem is not available. Ordinarily, we would have just pointed directly to the QuestionnaireItem, but the usage is subtely different between ResponseItem and QuestionnaireItem, so for now, we've modeled this as two separate classes.

Answer	answer	"The respondent's answer(s) to the question." - HL7 FHIR, QuestionnaireResponse.item.answer
String	definition	"A reference to an ElementDefinition that provides the details for the item. There is no need for this element if the item pointed to by the linkId has a definition listed." - HL7 FHIR, QuestionnaireResponse.item.definition
ResponseItem	item	"Questions or sub-groups nested beneath a question or group." - HL7 FHIR, QQuestionnaireResponse.item.item
String	linkId	"The item from the Questionnaire that corresponds to this item in the QuestionnaireResponse resource." - HL7 FHIR, QuestionnaireResponse.item.linkId Note that this is a required field in FHIR that is used to link a Questionnaire Response to its corresponding question. In the FHIM, this is handled through a pointer from the QuestionnaireResponse to the AssessmentInstrumentQuestion instance, and would ordinarily not be modeled further, as the FHIM is a logical model and is not concerned with implementation details. Nevertheless, this field is included for compatibility with FHIR, but we made it optional. [In a database, this would hold the primary key of the AssessmentInstrumentQuestion record, while the QuestionnaireResponse record would have a foreign key pointing to this record.]
String	text	"Text that is displayed above the contents of the group or as the text of the question being answered." - HL7 FHIR, QuestionnaireResponse.item.text
