So we were dispatched for a weak woman on side of street. Got there. She was 79 and altered. Didn't know her address couldn't really answer any questions. Obtained vitals and bgl. Couldn't obtain BP because everytime cuff would inflate she would move arm and start crying. Tried to obtain it 3 times without an accurate reading. Perform stroke scale. Equal grip strength no droopage or slurred speech no arm drift. Transport was only 5 min away. Called for als but they could not intercept. Got to the hospital and told nurse I couldn't get a bp and that we performed the stroke test but didn't find anything besides the confusion. Apprently they got a bp reading of 220/110 and brought her to cat and she was having a stroke. So now the nurse is very upset. I'm also upset with my self as well.
