Which finding indicates that a client may be at risk for coronary artery disease?

A triglyceride level of 180 mg/dL is significant because elevated triglycerides are associated with an increased risk of coronary artery disease (CAD). High triglyceride levels can contribute to the hardening and narrowing of the arteries, leading to atherosclerosis, which is a major risk factor for heart disease. Generally, triglyceride levels above 150 mg/dL are considered borderline high, and levels above 200 mg/dL are classified as high, indicating a higher likelihood of CAD. Thus, a finding of 180 mg/dL suggests that this client may need to be monitored closely for potential cardiovascular issues.

The other cholesterol levels mentioned do not indicate the same level of risk. HDL (high-density lipoprotein) cholesterol is often referred to as the "good" cholesterol, and a level of 50 mg/dL is considered acceptable, as higher levels offer some protective effect against heart disease. A total cholesterol level of 200 mg/dL is on the threshold of normal, and while it connects to overall cardiovascular risk, it alone may not signify an increased risk for CAD without consideration of the distribution between LDL and HDL. An LDL (low-density lipoprotein) cholesterol level of 90 mg/dL is typically viewed as favorable and
