I was at the hospital today and had a diabetic patient who I gave insulin to according to a sliding scale. The glucose was high, almost 400. But later on the patient was cold clammy and unresponsive. The glucose was so low the meter couldn't even read it it just said "lo error". It must have been below 11 because someone else said they once saw an 11 register on the same meter. The patient got a vile of dextrose IV push. Within a minute he woke up and asked what was going on. Re-checked glucose, checked vitals, notified physician, checked orientation, neuro assessment. Did I forget something? What should I look for/assess for more long term?
