Final answer:
An HDL cholesterol level of 90 mg/dL is within the expected reference range for a lipid panel report, indicating a lower cardiovascular risk compared to the elevated levels seen in other options provided.
Step-by-step explanation:
When explaining cardiovascular risk factors to a client based on their lipid panel report, the nurse should indicate that HDL cholesterol of 90 mg/dL is within the expected reference range. Healthy total blood cholesterol levels should be under 200 mg/dL.
A high amount of HDL, known as "good cholesterol transporter", indicates a reduced risk of cholesterol buildup in arteries, whereas a high amount of LDL, the "bad cholesterol transporter", suggests increased risk. A lipid panel indicates cardiovascular health by measuring total cholesterol, LDL cholesterol, HDL cholesterol, and triglycerides levels. The other options listed, such as LDL cholesterol of 160 mg/dL, triglycerides of 200 mg/dL, and total cholesterol of 240 mg/dL, are considered as exceeding the recommended levels for cardiovascular health and pose higher risks.
