Answer 7

The TEE shows normal left ventricular systolic function. Although any of these drugs might be used in various circumstances after CABG surgery, in this low risk case in which left ventricular function is normal just prior to separation from bypass, this patient might be managed without inotropes. While nitroprusside might be used to treat hypertension, and vasopressin might be used to treated vasoplegia, many patients like this can be managed without any drugs at all. Thus, while there is a no single correct answer, the most likely answer could be 5, none of the above.
