Final answer:
Signs and symptoms to watch out for in a sleeping 2-year-old child after a tonsillectomy include low blood pressure, frequent swallowing, nausea, and an increased heart rate.
Step-by-step explanation:
After a tonsillectomy, there are several signs and symptoms to watch out for in a sleeping 2-year-old child that would necessitate reporting and follow-up care. One such sign is a blood pressure of 96/64 mm Hg, which is lower than normal and could indicate bleeding or other complications. Another sign is frequent swallowing, which could be a sign of postoperative bleeding. Nausea and an increased heart rate (pulse of 110 beats/min) are also important to report and may require further evaluation.
