A 9-week-old infant is scheduled for a cleft lip repair. Which information is most important for the nurse to convey to the surgeon before transporting the infant to the surgical suite?

Answer: C. Red blood cell count of 2.3 cells/mcl or (2.3 x 10/L). Rationale: A. White blood cell count of 10,000/mm³ (10 x 10⁹/L): This is within the normal range for an infant, indicating no immediate concern for infection or immune response. It does not need to be urgently conveyed to the surgeon. B. Weight gain of 2 pounds (0.91 kg) since birth: This is a positive sign indicating healthy growth and nutritional status, but it is not a critical concern that would affect the immediate surgical plan. C. Red blood cell count of 2.3 cells/mcl or (2.3 x 10⁹/L): This low RBC count indicates anemia, which is critical information for the surgeon. Anemia can increase the risk of complications during and after surgery due to potential issues with oxygenation and healing, making it the most important information to convey. D. Urine specific gravity is 1.011: This indicates normal hydration status and is not immediately relevant to the surgical procedure. It does not need to be urgently reported to the surgeon compared to the low RBC count.
