- Call for AEMT/Paramedic intercept if needed & assist them in patient care.

- Consider other causes of nausea such as the following: cardiac, GI bleeding, pregnancy, toxicology, and diabetes.
- Nausea/vomiting is a common finding associated with acute coronary syndrome. Consider obtaining a 12-lead ECG when appropriate.
- Do not administer Ondansetron if the patient has known, prolonged QT on ECG.
