The nurse is admitting a client who states, “Last week I tripped over my grandson’s toys in the living room. I fell face first into the coffee table. I know I am taking blood thinners and am supposed to get checked out but I wasn’t confused afterwards and wasn’t having facial droop or anything like that. But today I was very dizzy and couldn’t keep on my feet. I have fallen about 4 times since then and now I have cuts all over my arms and I can’t lift my right arm up anymore.” Which part of that statement is the most concerning and needs immediate attention?
