Which precautions should the nurse implement? The client is NPO and is receiving total parenteral nutrition (TPN) via a subclavian line.

Place the solution on an IV pump at the prescribed rate.
Monitor blood glucose every six (6) hours.
Monitor intake and output every shift.

A. (correct) TPN is a hypertonic solution that has enough calories, proteins, lipids, electrolytes, and trace elements to sustain life. It is administered via a pump to prevent too rapid infusion. B. (correct) TPN contains 50% dextrose solution; therefore, the client is monitored to ensure that the pancreas is adapting to the high glucose levels. C. (incorrect) The client is weighed daily, not weekly, to monitor for fluid overload. D. (incorrect) The IV tubing is changed with every bag because the high glucose level can cause bacterial growth. E. (correct) Intake and output are monitored to observe for fluid balance. TEST-TAKING HINT: Options C and E refer to the same factor--namely, fluid level. The test taker should then determine if the time factors are appropriate. Weekly weighing is not appropriate so C can be eliminated.
