A patient's HDL, LDL, and triglyceride levels are 62, 77, and 60, respectively. What is the patient's total cholesterol score? S
Len [333]

Answer:

Total cholesterol score is 199

199 is high cholesterol score especially as it very close to 200. The patient should adopt diets that do not include high cholesterol food

Explanation:

a. Firstly, we want to calculate the patient’s total cholesterol score.

To get this, we use a mathematical approach.

Mathematically;

the total cholesterol score = HDL + TDL + Triglyceride = 62 + 77 + 60 = 199

The patient’s total cholesterol score is 199

b. As a doctor, I will advice the patient on the status of these measurements. Using the scale of cholesterol level, a measurement of total cholesterol = 200 represents a high cholesterol level. Since 199 is very close to 200, the patient is at a risk of high cholesterol levels and thus needs a dietary change.

For example, while controls are kept constant, or unmanipulated. Also, separate independent variables are strictly altered and analyzed - this guarantees validity and may show whether external influences affected the experiment. Here the variable being altered or measured is the food, and the resultant weight is the factor being observed.
