In which case would a patient most likely have an order to be NPO? ​

Quizplus · Accepted Answer

Patients preparing for endoscopy typically have orders to be NPO (nothing by mouth) for a certain amount of time prior to the procedure in order to ensure a clear view of the digestive system. A patient who had knee surgery yesterday (A) or a patient who is 85 years old (C) or a patient who is obese (D) would not necessarily have an order to be NPO unless they were undergoing a procedure that required it.
