IV, intravenous; K , potassium; plasmalyte is an isotonic crystalloid fluid with 10 mEq/L of potassium present in the solution.
a Stormy was given a 2.5% dextrose infusion with his IV fluids to ensure that his blood glucose did not drop due to the residual effects
of the insulin he had been given.
b His blood glucose had decreased to <20 mg/dL so an additional bolus of 10 mL of 25% dextrose was given to correct blood glucose.
c Dextrose supplementation was discontinued due to several normal blood glucose measurements after last dose of insulin 12 hours prior.
d KCl supplementation was added to ensure that the potassium levels did not fall significantly lower than this with prolonged fluid
therapy and the continuing post-obstructive diuresis Stormy was experiencing.
