Analyze coronary artery disease causes

Using the Cardiovascular Disease Risk Factors knowledge point, coronary artery disease (CAD) is characterized by the narrowing of the coronary arteries. This narrowing is caused by the accumulation of fatty deposits, cholesterol, and other cellular waste products, collectively known as plaque, along the inner walls of the arteries. This buildup restricts blood flow and oxygen delivery to the heart muscle.

Determine daily protein calorie percentage

Using the Macronutrient Functions knowledge point, the Acceptable Macronutrient Distribution Range (AMDR) established by nutritional guidelines recommends that adults consume 10–35% of their daily calories from protein. Among the given options, the range 10–15% represents a standard healthy minimum proportion of daily caloric intake dedicated to protein.

Evaluate cardiovascular fitness and resting heart rate

Using the Cardiovascular Adaptations knowledge point, regular aerobic exercise strengthens the heart muscle, allowing it to pump a greater volume of blood with each beat (increased stroke volume). Because the heart becomes more efficient, it does not need to beat as frequently to maintain adequate circulation at rest. Therefore, as cardiovascular fitness improves, resting heart rate decreases rather than increases, making the statement false.
