Brief Summary
-----------------
This is a quality improvement project that aims to assess the effect of nurse-driven administration of essential oil aromatherapy on postoperative nausea and vomiting (PONV) in patients while in the post-anesthesia care unit (PACU) after general anesthesia.

Detailed Description
