The answer to this is the nurse should verify if the client has done NPO eight hours before the time of the surgery. If you are not familiar with NPO, this means Nil Per Os. This means that the person should not get any food or drink through the mouth for eight hours.
There are some surgical procedures that may cause the patients to vomit or aspirate so doing this can help prevent any discomfort that may happen. There are still other things that the nurse may do but this is the most important task that the nurse has to check before the surgery proceeds.
Verifying the client has been NPO since midnight. or at least 8 hours before surgery.
Maintaining NPO status for at least 8 hours before surgical procedures prevents vomiting and aspiration. There is no need to patch an eye before most surgeries or to clip the eyelashes unless specifically ordered by the physician. The physician is responsible for obtaining informed consent; the nurse validates that the consent is obtained.
