For a newborn with a colostomy after anal agenesis who has had three loose stools since surgery yesterday, which nursing diagnosis has the highest priority?

• A. Potential for fluid volume deficit.
• B. Alteration in bowel elimination.
• C. Pain related to postoperative condition.
• D. Anxiety of parents related to newborn's condition.

Answer: (A)

Maintaining fluid and electrolyte balance in a neonate with a new ostomy is the most urgent concern. Newborns have very limited fluid reserves, and ostomy stool losses can be both substantial and electrolyte-rich. Three loose stools in the first day after surgery signals ongoing, potentially rapid fluid loss, which can quickly lead to dehydration and hypovolemia if not monitored and managed closely. The highest-priority nursing focus is to assess hydration status and ensure adequate fluid intake or IV support as ordered, watching for signs such as changes in mucous membranes, fontanelle sagging, skin turgor, weight loss, and urine output (in infants, a normal target is roughly 1–2 mL/kg/hour). Addressing fluid volume deficit promptly helps prevent progression to shock and supports stable organ perfusion.

Pain, bowel elimination patterns, and parental anxiety are important elements of care, but they do not pose the same immediate threat to the newborn’s life if fluid balance is preserved.
