/// MedicationAdministration records the event of a patient actually consuming or
/// otherwise being administered a medication. In FHIR R5 it represents the point
/// in the medication process where a dose is given, as opposed to being ordered
/// or dispensed, and it captures who received the medication, what was given,
/// when and where it occurred, the dose and route, and who performed the act.
/// An administration can be as simple as swallowing a single tablet or as
/// involved as a long running intravenous infusion recorded over a period of
/// time. Clinically and administratively it supports medication reconciliation,
/// adherence monitoring, billing, safety surveillance, and audit of the
/// medication administration record (MAR). The event ties back to the
/// authorizing request or prescription and to the specific encounter between the
/// patient and the health care practitioner. It can also record that a planned
/// dose was intentionally withheld or wasted by using a status of not-done
/// together with an appropriate statusReason.
///
/// Related resources: the recipient is referenced through [`subject`], typically
/// a [`Patient`](crate::r5::resources::patient::Patient); the context is the
/// [`Encounter`](crate::r5::resources::encounter::Encounter); the substance is
/// described via a [`CodeableReference`](crate::r5::types::CodeableReference) to
/// a [`Medication`](crate::r5::resources::medication::Medication); and the
/// authorization is the associated
/// [`MedicationRequest`](crate::r5::resources::medication_request::MedicationRequest).
/// See also `MedicationDispense` and `MedicationStatement` for other stages of
/// the medication process.
