Akimi4 [234]

After a tonsillectomy, the nurse should review PHCP’s postoperative prescription and prescribe suction every 2 hours.

The surgical removal of the tonsils, which are two oval-shaped tissue pads located in the back of the throat, one on each side, is known as a tonsillectomy. Suction equipment should be accessible after a tonsillectomy, but due to the danger of trauma to the surgical site, suctioning is rarely done until there is an airway obstruction. After any kind of surgery, it's important for nurses to keep an eye out for bleeding. Initially, milk and milk products should be avoided since they coat the throat, make the child clear their throat, and raise the risk of bleeding. It is recommended to drink cool, clear beverages.
