Category - Patient Care

You are caring for a child who is going to have a tonsillectomy. Which of the following laboratory results would you want to check the values of preoperatively?

  1. Prothrombin time
  2. Sedimentation rate
  3. Blood urea nitrogen
  4. Creatinine
Explanation

Answer: A - The nurse would want to check the Prothrombin time preoperatively and report any abnormal results to the surgeon. The tonsillar area is very vascular, which can increase the patient’s chance of bleeding. If the prothrombin time is not therapeutic the patient could bleed to death. The nurse would want to ensure that the patient is not at risk prior to the surgery.
