As a PACU RN, your responsibilities are to monitor post-anesthesia care unit patients and ensure they recover properly from anesthesia after inpatient or outpatient surgeries or procedures. PACU RNs have a range of post-operative duties, including checking and changing bandages, administering post-operative medications, such as painkillers or antibiotics, and providing patients and their families with information about care after they leave the recovery room. PACU RNs address any issues with recovery and collaborate with physicians or surgeons whenever necessary.
