The nurse is caring for a patient who has been on total parenteral nutrition (TPN) for 48 hours. The nurse demonstrates the most effective nursing care by:
a. checking the patient's blood glucose level according to facility protocol.
b. speeding up the solution if the prescribed intake falls behind.
c. informing the patient that TPN can only be administered via a central line for 1 week.
d. monitoring the peripheral IV site of TPN infusion for signs of infiltration at least every 8 hours.
A
The hypertonic solution causes difficulty with glucose tolerance, so monitoring of blood glucose level is imperative. The infusion rate should never be increased to "catch up" because of the like-lihood of fluid overload caused by the hypertonicity of the TPN. TPN can be administered for more than 1 week, and TPN is almost always administered via a central line rather than a peri-pheral line.
