A nurse is monitoring a child who is postoperative following a tonsillectomy for signs of hemorrhage. Which of the following findings is a sign of this postoperative complication?

A. Frequent swallowing is a common finding after a tonsillectomy due to postoperative throat discomfort and the sensation of having a foreign object in the throat (such as blood clots or mucus). B. Reports of thirst may indicate dehydration, which can occur after surgery, especially if the child is not drinking enough fluids due to pain or discomfort. While dehydration can be a concern after a tonsillectomy, it is not a specific sign of hemorrhage. C. Pain is common after a tonsillectomy and can be expected in the postoperative period. While increased pain may be present if hemorrhage occurs, it is not a specific sign of hemorrhage on its own. D. Mouth breathing does not directly indicate bleeding and is more related to discomfort or difficulty breathing through the nose, especially if the child is experiencing throat pain. It is not a typical sign of hemorrhage.
