Answer to Question 1

Correct Answer: 79 grams
To calculate this patient's weight in kg, divide the weight in lbs. by 2.2 or 231/2.2 = 105 kg. Then multiply the prescribed amount of protein by the weight in kg or 0.75 grams  105 = 78.75 grams. When rounded, the patient should be instructed to ingest 79 grams of protein each day.

Answer to Question 2

Correct Answer: 1
Blood flow through the coronary arteries is primarily regulated by the aortic blood pressure. Blood vessel dilation is a secondary factor that regulates blood flow through the coronary arteries. The systemic circulation is a high-pressure circulation system. Draining of blood into the coronary sinus by the coronary veins does not regulate blood flow through the coronary arteries.
