The nurse is conducting an education class about myocardial blood supply for patients with coronary artery disease (CAD). The nurse determines that learning has occurred when the patients make which statement(s).
 
  1. The heart has right and left arteries that arise from the aorta.
  2. The coronary arteries carry blood away from the heart to the right atrium.
  3. Anastomoses are small arteries that supply blood to the heart.
  4. Coronary arteries primarily carry blood to the left ventricle.
  5. The right and left arteries have smaller branches that go around the heart.

Question 2

The patient says to the nurse, My doctor said I can't have fried chicken anymore because I have heart disease. I've eaten it all my life and am fine except for some indigestion lately. What is the best response by the nurse?
 
  1. Did your doctor mention exercise? That is the most important lifestyle change to slow the progression of your heart disease.
  2. Your indigestion is an indication that your body cannot tolerate fatty foods; this causes an increased workload for your heart.
  3. Fried chicken is actually okay, but you must be very careful with the type of fat that you fry the chicken in.
  4. Your indigestion could actually be chest pain caused by narrowed coronary arteries; you will need a low-fat diet.

Answer to Question 1

Correct Answer: 1,3,5
Rationale: The myocardium receives blood from the right and left coronary arteries that arise from aortic sinuses at the base of the aorta. These divulge into smaller branches that encircle the heart. Numerous smaller vessels, known as anastomoses, serve as communication networks among the coronary arteries. The coronary veins, not arteries, carry blood to the right atrium. The coronary arteries supply blood to all areas of the heart, not primarily the left ventricle.

Answer to Question 2

Correct Answer: 4
Rationale: The most common etiology of coronary artery disease (CAD) in adults is atherosclerosis, the presence of plaque within coronary walls. To decrease this, patients should eliminate foods high in cholesterol or saturated fats. Some patients experience angina pain in the midepigastrium, which is an indication of coronary artery disease (CAD) not an intolerance of fatty foods. Exercise is only one of several important healthy lifestyle habits to prevent or slow the progression of coronary artery disease (CAD). The patient should not consume chicken fried in any type of fat since foods that are high in saturated fats should be avoided.
