A nurse is caring for a child who is postoperative following a tonsillectomy. Which of the following findings indicates that the child may be experiencing hemorrhage?

A. Pain is expected post-tonsillectomy, especially with swallowing, and does not indicate hemorrhage by itself. B. Drowsiness could result from analgesics or anesthesia but is not a key indicator of bleeding. C. Diminished breath sounds may indicate airway obstruction or aspiration but not specifically hemorrhage. D. Frequent swallowing (or clearing the throat) is an early sign of postoperative bleeding, as the child swallows blood trickling down the throat rather than spitting it out. Other signs may include pallor, tachycardia, or bright red emesis.
