Dont' know if this qualifies as a first, bit a DUH just the same. Toned out at 2 a.m. been asleep about 2 hours) to a pt with abdominal pains. Arrive on scene to find an elderly Pt. sitting up on bed clutching a small waste can trying to vomit. Assessment revealed classic textbook signs of STROKE. Packaged him up and was heading out the door when ALS arrived. While giving report, I said "breath sounds are round and reactive to light". He looked and said OK, and how are his eyes. I realized what I had said and replied " clear bilaterally" We had a laugh over that one.
