A nurse is caring for a client who is receiving total parenteral nutrition (TPN). The nurse notices that the solution bag is almost empty and there is not another bag of TPN to administer. Which of the following IV solutions should the nurse administer until the next bag of TPN solution is available?
59% dextrose in lactated Ringer's solution (DLR)
0.45% sodium chloride (0.45% NaCl)
10% dextrose in water (DW)
Lactated Ringer's solution
The Correct Answer is C
Rationale:
A. 59% dextrose in lactated Ringer’s is not a standard solution and would be hypertonic and unsafe.
B. 0.45% sodium chloride does not provide the glucose necessary to prevent hypoglycemia.
C. 10% dextrose in water (D10W) is correct. If TPN runs out, a dextrose-containing solution should be administered to prevent hypoglycemia until the next TPN bag is available.
D. Lactated Ringer’s does not provide sufficient glucose to maintain blood sugar during TPN interruption.

B. Encouraging ambulation once the client is fully awake helps prevent complications such as atelectasis, deep vein thrombosis, and promotes bowel function.
