Question

part 4 (contd)
click one of the arrows to see how viviana’s cholesterol levels change if she
changes her intake of a particular type of fat for a period of two months. notice
the blood test results that appear in the after column of the table after you
click the arrow. these results will change when you select a different arrow.

click the notebook icon to record your observations after clicking each of the
four arrows. when you are finished collecting data for viviana, click the next
patient button.

Explanation:

This is an interactive task description rather than a question with a solvable problem (like a calculation or a question needing an explanation). It's guiding the user on how to interact with a software or simulation to observe changes in Viviana's cholesterol levels by clicking arrows and recording data. Since there's no specific question (e.g., calculate the change, determine a trend, answer a factual question about cholesterol) provided, we can't proceed with a solution.

If you want to analyze the cholesterol levels (e.g., compare before and after, see how far from optimal), or have a specific question about the data or the task, please clarify. For example, if you want to know how much Viviana's LDL is above the optimal before the change, we can calculate that:

Step1: Identify LDL before and optimal

LDL before: $185$ mg/dL, Optimal LDL: $<100$ mg/dL (we'll use $100$ for the difference calculation)

Step2: Calculate the difference

Difference = LDL before - Optimal LDL limit = $185 - 100 = 85$

Answer:

Viviana's LDL is $85$ mg/dL above the optimal limit (of $100$ mg/dL) before any fat intake changes.
