Continuity mistake: Luka is in talking to the first possible kidney transplant patient - he puts his pen into his pocket and is holding the chart in his other hand, also up by his chest. As he says "Minneapolis", the shot changes and we see him put his pen in his pocket again and his chart is down by his waist - there was no time for the shift.
