A. It eliminates pain, reduces cardiac workload, and increases myocardial contractility. B. It lowers resistance, reduces cardiac workload and decreases myocardial oxygen demand. C.

The answer to this is B. This will help decrease the amount of oxygen the heart needs in order to keep on going. The reason why morphine is given is it will be able to get rid of the uncomfortable symptoms.
