A client in DKA has an order for an insulin infusion at 5 units per hour. The nurse is setting up IV insulin, 100 units/100 mL as a secondary line, with D10W as the primary infusion. The nurse follows the 6 rights of medication administration, clamps the secondary tubing, spikes the insulin bag, squeezes the chamber until it is ⅔ full, and slowly opens the roller clamp to prime the tubing. The nurse then cleanses the Y-port closest to the client and connects the secondary tubing, ensuring the bag is hanging above the primary infusion. The pump is programmed to run the secondary infusion at 5 mL per hour, so the nurse starts the pump. Which statement correctly describes what is wrong with this situation?
