A client is receiving intravenous fluids postoperatively following cardiac surgery. The nurse plans to explain to the family that nursing assessments will focus on which potential postoperative complication?
1. Fluid volume deficit
2. Fluid volume excess
3. Liver failure
4. Seizure activity
2. Fluid volume excess
Rationale:
Antidiuretic hormone (ADH) and aldosterone levels are commonly increased following the stress response before, during, and immediately after surgery. This increase leads to sodium and water retention. Adding more fluids intravenously can cause a fluid volume excess and stress upon the heart and circulatory system. A fluid volume deficit would not occur with the administration of intravenous fluids. Liver failure is not anticipated related to postoperative intravenous fluid administration. Seizure activity would more commonly be associated with electrolyte imbalances.
