Diagnosis & Interpretation
Interpretation:
Differentials:
- Ectopic pregnancy
? This is the key differential to rule out. Pregnancy must be excluded in all females of child bearing age
- Ovarian torsion
- Ovarian cyst +/- rupture
- PID
- Gastroenteritis
At this point - regardless of their answers, you should inform the candidate that the main differential is Appendicitis, and prompt them to move onto the next step.
