An ER physician would have ordered, usually regardless of symptoms, a CBC, Chem 20, UA, beta-HCG, and probably a UDOA to start with and then depending on her symptoms they would have ordered additional testing (ABG if worried about arterial pH balance). Fairly easy to rule out that of which you mention. I don't know what is up with Nunes but the diagnoses/conditions of which you mention are easy to diagnose and those tests, when ordered in an ER, take at most a hour (usually less) to get results.
