1)  A nurse is caring for a client who has completed 10 daily cycles of Total parenteral Nutrition (TPN). Which of the following findings indicates that the client is receiving adequate TPN supplementation.

a.   Improved Mobility

b.   Weight gain of 9.1 kilograms to 20 pounds

c.   Potassium level of 2.5 meq/l

d.   BUN level of 15 mg/dL 

The most correct option is

d. BUN level of 15 mg/dL

Step-by-step explanation

The given bun level falls on normal range. Potassium level is very low meaning the total permanent nutritional therapy is not properly working. Weight gain of such level is not possible in 10 cycles.

Mobility is an abstract determinant to check the working of total permanent nutrition. Because we bypass the Gastrointestinal tract to given aminoacid and minirals and other dietary supplements, the normal range would indicate the working of such nutritional therapy.
