Which client on an acute care pediatric unit requires the nurse's immediate attention?

While pain management is important following a cleft palate repair, it does not typically require immediate attention. Pain can be managed with appropriate analgesics and does not typically present an immediate risk to the patient's health. A patient refusing to ambulate following an appendectomy does not typically require immediate attention. Encouraging mobility is important for recovery, but refusal to ambulate does not present an immediate risk to the patient's health. Frequent swallowing following a tonsillectomy could indicate post-operative bleeding, which requires immediate attention. Post-tonsillectomy hemorrhage can be a life-threatening condition that requires immediate intervention. While pain at the site of an IV infusion should be addressed, it does not typically require immediate attention unless there are signs of infection or infiltration. It does not present an immediate risk to the patient's health.
