Assessment

- History ‒ a separate history for both nausea and vomiting:
- triggers, volume, pattern
- exacerbating and relieving factors, including individual and combinations of drugs tried and routes used
- bowel habit
- medication – consider drugs that may:
- contribute to the nausea and vomiting
- cause harm
- not take effect due to the nausea and vomiting
- exclude regurgitation as this will require a different approach. If suspected consider seeking advice
- check for other concurrent symptoms.
- Examination:
- general review for signs of dehydration, sepsis and drug toxicity
- central nervous system
- abdomen (for example organomegaly, bowel sounds, succussion splash)
- check temperature, pulse and respiration
- Blood investigations where appropriate may include:
- urea and electrolytes
- liver function tests
- calcium
- blood glucose.
- Consider excluding urinary infection.
