Hi all! This is my 3rd week on an orthopedic floor (did LPN to RN transition) and had a slight confusion when talking to a nurse manager. The floor just received tele and none of the floor nurses knew how to interpret EKGs and asked for my help. As an LPN and refresher in RN courses, I have always been taught to count the "half boxes," and to be as precise as possible. As I was showing the floor nurses, the nurse manager busted out of her office and immediately told everyone never to count half boxes, always round up. Even in orientation the ICU nurse taught half boxes...I just don't like "guesstimating" what my pts ekg measurements are. Even thought the answers are only slightly different, she seemed very offended to tell anyone to count half boxes...any insight?thanks!
