The nursing team is reviewing the care plan for a patient having ileostomy surgery that day. One of the postoperative patient problems is risk for deficient fluid volume. What does the Licensed Practical Nurse know is the reason for this risk?

Rationale: A. An ileostomy diverts intestinal contents from the ileum (small intestine) to an external stoma, bypassing the colon. The colon normally absorbs water and electrolytes from stool. Without this absorption, patients are at risk for excessive fluid and electrolyte loss, which can lead to deficient fluid volume if not carefully monitored and managed. B. While some patients may have decreased appetite after surgery, anorexia is not the primary reason for fluid volume risk. The main concern is fluid loss through the stoma, not decreased intake. C. Blood loss during ileostomy surgery is generally moderate and controlled, and it is not the primary factor leading to postoperative fluid volume deficit. Fluid imbalance in these patients is primarily due to intestinal fluid loss. D. Patients are typically encouraged to maintain adequate hydration postoperatively. Fluid intake is not routinely restricted, and doing so would increase the risk of deficient fluid volume.
