Final answer:
Total cholesterol, LDL cholesterol, and liver enzymes (ALT) should be monitored in pts taking statins.
Step-by-step explanation:
When taking statins, the blood levels that should be monitored are the levels of total cholesterol, LDL (bad cholesterol), and liver enzyme (alanine aminotransferase or ALT). Statins work by reducing the production of cholesterol in the liver, so monitoring the cholesterol levels in the blood will help assess the effectiveness of the medication. Additionally, statins can potentially cause liver damage, so monitoring the liver enzymes is essential to ensure the safety of the patient.
