A nurse is monitoring a child for manifestations of hemorrhage following a tonsillectomy. Which of the following findings is a manifestation of this postoperative complication?

Rationale: A. Mouth breathing is common after tonsillectomy due to swelling and discomfort, not a sign of hemorrhage. B. Thirst is nonspecific and may result from NPO status or mouth dryness, not necessarily hemorrhage. C. Frequent swallowing is a classic early sign of hemorrhage because the child may be swallowing blood that trickles down the throat. D. Pain is expected after tonsillectomy and is not specific for hemorrhage.
