One of the things a PACU nurse do, is to render health teachings to his/her patient. It is essential for this nurse to give health teachings so as to help with the recovery of the patient’s health status. Encouraging deep breathing exercises is one of the instructions that is given especially if the patient has respiratory problems. Teaching the patient how to use the spirometer is also done if it is being ordered by the physician. Being a PACU nurse entails a great responsibility in the post anesthesia care of the patient.
