A client with a history of inflammatory bowel disease develops severe ulcerative colitis and is admitted to the intensive care unit after surgery for a fistula repair. Which intervention is most important for the nurse to include in the plan of care?

A. Recording wound drainage is important, but fluid management takes priority due to the risk of dehydration and electrolyte imbalances. B. Turning the client every 2 hours is helpful for preventing pressure ulcers, but fluid replacement takes precedence. C. Clients with ulcerative colitis, especially after surgery, are at high risk for fluid and electrolyte imbalances due to diarrhea and fistula drainage. Ensuring appropriate fluid replacement is vital to maintaining hemodynamic stability. D. Assessing skin condition is important, but it is secondary to managing fluid and electrolyte balance in this situation.
