A nurse is assessing a child who is postoperative following a tonsillectomy. Which of the following findings is a manifestation of hemorrhage?

A. Frequent swallowing is a classic sign of post-tonsillectomy hemorrhage, as the child may be swallowing blood that is draining down the throat. This can be a subtle but early indicator of bleeding and requires immediate evaluation. B. Increased pain is expected in the immediate postoperative period and not specific to hemorrhage. C. Drooling may be due to throat pain or refusal to swallow but is not a key indicator of bleeding. D. Poor fluid intake is common after tonsillectomy due to pain and discomfort, but not specific to hemorrhage.
