Question with a combination of a numeric value and unit, potentially with a comparator (< , >, etc.) as an answer. (valueQuantity).

There is an extension "http://hl7.org/fhir/StructureDefinition/questionnaire-unit" that can be used to define what unit should be captured (or the unit that has a ucum conversion from the provided unit).

You can use the UnitOption extension to specify a list of options for the unit of a quantity item.
