Answer
I would expect it to be higher. There is a higher concentration of potassium ions in the ICF than ECF. Upon trauma, the cells lyse and the potassium is released into the ECF.
Work Step by Step
The blood potassium level will be higher than normal. When trauma occurs, the cells lyse and spill their contents into the ECF. Since there is a higher concentration of potassium ions in the ICF, these will spill out into the ECF, raising the ECF's concentration of potassium.
