A nurse is caring for a client who is receiving parenteral nutrition (PN) through a central venous catheter (CVC).
The current PN bag is empty, and a new PN bag is not available at this time.
Which of the following solutions should the nurse infuse until a new PN bag is available?
0.9% sodium chloride has an osmolarity of about 300 mOsm/L, which is lower than PN solutions and can cause fluid overload and electrolyte imbalance.
Lactated Ringer’s has an osmolarity of about 275 mOsm/L, which is also lower than PN solutions and can cause similar problems as 0.9% sodium chloride.
Dextrose 10% in water. This is because parenteral nutrition (PN) is a mixture of nutrients that is given through a central venous catheter (CVC) that goes directly to the heart. PN contains high concentrations of nutrition and calories, and if the PN bag is empty, it needs to be replaced with a solution that has a similar osmolarity to prevent complications such as hypoglycemia (low blood sugar) or phlebitis (inflammation of the vein). Dextrose 10% in water has an osmolarity of about 500 mOsm/L, which is close to the osmolarity of PN solutions.
Dextrose 5% in water has an osmolarity of about 250 mOsm/L, which is much lower than PN solutions and can cause rapid drop in blood sugar and vein irritation.

Choice A is wrong because 0.9% sodium chloride has an osmolarity of about 300 mOsm/L, which is lower than PN solutions and can cause fluid overload and electrolyte imbalance.
Choice B is wrong because lactated Ringer’s has an osmolarity of about 275 mOsm/L, which is also lower than PN solutions and can cause similar problems as 0.9% sodium chloride.
Choice D is wrong because dextrose 5% in water has an osmolarity of about 250 mOsm/L, which is much lower than PN solutions and can cause rapid drop in blood sugar and vein irritation.
