criteria are met.
Rationale:LA County EMS uses a trauma triage decision tree that triggers trauma center
transport if any of the physiologic, anatomic, or mechanism criteria are met. A GCS 13 and
systolic BP <90 mmHg are physiologic criteria, so the patient qualifies for trauma center
transport. Option D correctly applies the protocol. Other options either delay transport or
violate the protocol.
Q2.

that can be administered by paramedics under standing orders, but the dose is 4 mg IV/IO.

Rationale: LA County protocols for ondansetron specify IV/IO administration; paramedics can
administer it under standing orders without contacting the base. The MICN should not
approve an off-protocol route. Denying and referring to the standing order ensures protocol
adherence. Options C and D are not indicated as the IV/IO route is available and appropriate.
Q3.
When providing online medical direction, an MICN must document all communications
with field personnel. Which element is absolutely essential to include in the
documentation to meet LA County EMS requirements?
A. The paramedic's certification number B. The patient's insurance information

not necessary, though the name is.
