A client's total cholesterol level is 344 mg/dL (8.6 mmol/L), low-density lipoprotein cholesterol (LDL-C) level is 164 mg/dL (4.25 mmol/L), and high-density lipoprotein cholesterol (HDL-C) level is 30 mg/dL (1.2 mmol/L). Based on analysis of the data, how should the nurse direct client teaching?

1. The client should maintain the current dietary regimen but increase activity level.

2. Results are inconclusive unless the triglyceride level is also screened, so teaching is not indicated at this time.

3. The client is at high risk for cardiovascular disease, and measures to modify all identified risk factors should be taught.

4. The client is at low risk for cardiovascular disease, so the client should be encouraged to continue to follow the current regimen
