What nursing diagnosis is the most important for the nurse to include in the care plan of Mrs.Everly who has just been started on total parenteral nutrition (TPN) therapy?

A) Risk for infection
B) Imbalanced nutrition: less than body requirements
C) Activity intolerance
D) Fluid volume deficit

The most important nursing diagnosis to include in the care plan of Mrs. Everly who is on TPN therapy is the risk for infection. TPN therapy introduces a foreign substance into the body, and so the risk for infection is high. The nurse should monitor the patient for signs and symptoms of infection and take appropriate measures to prevent it. Imbalanced nutrition, activity intolerance, and fluid volume deficit may also be relevant nursing diagnoses, but the risk for infection takes priority.
