NCLEX Practice Test

This indicates that the client may be experiencing dehydration. This is because total parenteral nutrition, or TPN, provides all of the necessary nutrients and fluids intravenously. Therefore, an increase in urine output could suggest that the client is not absorbing enough of the fluid from the TPN, resulting in dehydration. B Hyperglycemia is an increased level of glucose in the blood and would not typically cause an increase in urine output. C: Hypokalemia is a low level of potassium in the blood and would not typically cause an increase in urine output. D: Infection may cause an increase in urine output, but it would not be attributed to the total parenteral nutrition. Further assessment and investigation would be needed to determine the underlying cause of the increased urine output in this case.
