The nurse is conducting client teaching about cholesterol levels. When discussing the client's elevated LDL and lowered HDL levels, the client shows an understanding of the significance of these levels by making what statement?
"Increased LDL and decreased HDL increase my risk of coronary artery disease."
"Increased LDL has the potential to decrease my risk of heart disease."
"The decreased HDL level will increase the amount of cholesterol moved away from the artery walls."
"The increased LDL will decrease the amount of cholesterol deposited on the artery walls."
The Correct Answer is A
Elevated levels of LDL (low-density lipoprotein) cholesterol are associated with an increased risk of coronary artery disease (CAD). LDL cholesterol is often referred to as "bad" cholesterol because it can contribute to the formation of plaque in the arteries, leading to narrowing and blockage of the arteries supplying the heart. This increases the risk of developing CAD and related complications such as heart attack and stroke.
On the other hand, HDL (high-density lipoprotein) cholesterol is often referred to as "good" cholesterol. HDL cholesterol helps remove excess cholesterol from the bloodstream and transport it back to the liver for processing and excretion. Higher levels of HDL cholesterol are associated with a decreased risk of CAD because it helps to prevent the accumulation of cholesterol on artery walls.
Therefore, understanding that increased LDL and decreased HDL levels increase the risk of coronary artery disease demonstrates a good understanding of the significance of cholesterol levels and their impact on cardiovascular health.

Explanation
Pain level of 10 out of 10: Severe pain can stimulate the sympathetic nervous system and result in an increased heart rate.
Temperature 101.9°F: Fever can lead to an elevated heart rate as the body's response to infection or inflammation.
Hemoglobin: 7 g/dL: Low hemoglobin levels, known as anemia, can cause the heart to pump faster in an attempt to compensate for the decreased oxygen-carrying capacity of the blood.
Cocaine abuse: Cocaine is a stimulant drug that can significantly increase heart rate and cause tachycardia.
The following clinical finding would not typically be associated with tachycardia:
Blood glucose 90 mg/dL: While low or high blood glucose levels can cause symptoms, they are not directly associated with tachycardia unless they lead to significant physiological stress or hormonal imbalances.
Correct Answer is A
Explanation
ST-segment elevation during exercise stress testing is a concerning finding that may indicate reduced blood flow to the heart muscle. It can be a sign of myocardial ischemia or coronary artery disease. Cardiac catheterization is a diagnostic procedure that allows direct visualization of the coronary arteries and helps identify any blockages or narrowing that may be causing the ST-segment elevation.
Here's an explanation of why the other options are not the most appropriate procedures:
Transesophageal echocardiogram: Transesophageal echocardiogram (TEE) is a diagnostic test that involves inserting a probe into the esophagus to obtain detailed images of the heart. It is not typically used to evaluate ST-segment elevation, which primarily indicates coronary artery issues rather than structural abnormalities.
Telemetry monitoring: Telemetry monitoring involves continuous monitoring of a patient's heart rhythm and can be used for various cardiac conditions. While telemetry monitoring may be necessary for ongoing cardiac assessment, it is not a specific procedure to address the ST-segment elevation found during the exercise stress test.
Pharmacologic stress test: A pharmacologic stress test is an alternative to an exercise stress test for patients who cannot exercise. It involves administering medications that stimulate the heart to mimic the effects of exercise. While a pharmacologic stress testcan also reveal ST-segment changes, the presence of ST-segment elevation usually requires further evaluation with a more invasive procedure like cardiac catheterization.
