With appropriate definitions in the QRD and/or QRF segments, the RDE, RDS, RGV, and RAS messages can serve as models for result-oriented pharmacy/treatment queries returning the current profile of pharmacy or treatment orders (RDE type), the current dispense history (RDS type), the current dose history (RGV type), or the current administration record (RAS type). Examples are given in Section 4.8.16.3, "Alternating IV Order Messages."
