Final answer:
Morphine is given in Acute Coronary Syndrome because it reverses the effects of catecholamine release, acts as a vasodilator, and assists in redistributing blood flow. The option (D) is correct.
Step-by-step explanation:
Morphine is given in Acute Coronary Syndrome because of all of the above. Morphine has multiple benefits in treating Acute Coronary Syndrome. It reverses the effects of catecholamine release on the body, which helps lower myocardial oxygen demand.
It also acts as a vasodilator, reducing oxygen requirements and left ventricular preload. Additionally, it assists in redistributing blood flow in patients with acute pulmonary edema. Therefore, option (D) is correct.
