A nurse is providing discharge teaching to the guardian of a preschooler who had a tonsillectomy. Which of the following statements should the nurse include?

A. "Notify the provider if your child has dark brown blood between their teeth.": Dark brown or old blood is generally not a sign of active bleeding after a tonsillectomy. Concern should focus on bright red blood, which may indicate postoperative hemorrhage requiring prompt medical attention. B. "Notify the provider if your child is swallowing frequently.": Frequent swallowing can be an early sign of active bleeding in the throat after a tonsillectomy. Parents should be instructed to monitor for this symptom and notify the provider immediately, as it may indicate postoperative hemorrhage. C. "Encourage your child to clear their throat as needed.": Clearing the throat can disrupt the surgical site and increase the risk of bleeding. Children should be advised to avoid throat clearing and coughing to allow proper healing. D. "Encourage your child to drink liquids through a straw.": Using a straw can create suction that may dislodge the surgical site and lead to bleeding. Children should be encouraged to sip liquids gently without a straw to prevent trauma to the tonsillar area.
