A client with coronary artery disease is being prepared for a coronary arterial bypass graft sur-gery. The nurse knows that the coronary artery that carries the most blood and can cause the most harm when blocked is the:
1. Left coronary artery
2. Posterior interventricular artery
3. Circumflex artery
4. Anterior interventricular artery
ANS: 1
The left coronary artery, the most abundant blood supply, feeds the left ventricular myocardium, which is more muscular and does most of the heart's work. The posterior and anterior interven-tricular arteries supply blood to the walls of both ventricles. The circumflex artery supplies blood to the walls of the left atrium and left ventricle.
