Patient assessment should be as comprehensive and pertinent as possible before asking for a medical intervention.
Taking the patient's pulse: It will be tachycardic due to pain.
Patient's pallor: Pale, sweating, feeling cold extremities.
Assessing how the patient is able to move? Try to observe when unnoticed. A patient in any kind of abdominal pain will be unable to be relaxed or stand and move easily.
I would do as many of these observations as able before making a referral to a Medic. I believe the Pulse is probably the best indication of what might actually be going on.
