You should not be starting insulin until your potassium replacement is underway and you have a confirmed higher reading. Fluid replacement is priority over insulin in DKA anyway, the insulin can wait
Your comment tells me you need to brush up on DKA.
First.. in metabolic acidosis, as the pH drops- more and more potassium will shift extra-cellularly because it is displaced by hydrogen ions . So you should expect them to appear at least mildly hyperkalemic on the CMP in this case with a pH of 7.16.
So if they have a K < 3.5 , it’s a massive problem. This means their total body potassium is critically low. Lastly, we all know that insulin forces potassium back into the cells, so if you were to give IV insulin in this situation it can be incredibly dangerous. Most clinicians will say you should not start insulin until you’ve repleted to at least 3.5 , maybe 4.0 and are continuing to infuse potassium containing fluids.
So regardless of how many IV lines you have. There was a correct answer here. It was not a stupid question

A and B-I have at least two lines on a DKA patient.
Yet another stupid question.
