I work for a public

I work for a public ALS EMS district that does 911 calls and emergent transfers. Upon picking a patient up off the hospital floor for a transfer, I had a registered nurse tell me she hadn’t given the patient any pain meds in several hours because the patient was allergic to them. Wondering why you’d give them in the first place if she was allergic to them, I requested she describe allergy. “Well I gave her 2mg of Haldol and 2mg of Morphine @1230 and she developed an altered mental status!”
