A 4-year-old child is admitted to the pediatric unit for a tonsillectomy. during preoperative planning a nurse reviews the child's laboratory report. which lab value is of most significance in this situation? 1 potassium level 2 coagulation studies 3 red blood cell (rbc) count 4 erythrocyte sedimentation rate (esr)

Respuesta :

Coagulation Study! Tonsillectomy may result in hemorrhage because of the vascularity of the oropharynx; clotting function must be adequate. The potassium level, RBC count, and ESR are not significant in this type of surgery if the child is otherwise healthy.

Test-Taking Tip: Eat breakfast or lunch before an exam. Avoid greasy, heavy foods and overeating. This will help keep you calm and give you energy.
