Correct Answer is C

Comment:

Postoperative nausea and vomiting (PONV) typically occurs in 20 to 30% of surgical cases, with considerable variation in frequency reported between studies (range, 8-92%). PONV is generally considered a transient, unpleasant event carrying little long-term morbidity; however, aspiration of emesis, gastric bleeding, and wound hematomas may occur with protracted or vigorous retching or vomiting. Troublesome PONV can prolong recovery room stay and hospitalization and is one of the most common causes of hospital admission following ambulatory surgery.
