Answer to Question 1

ANS: B
Reductions in LDL cholesterol are significant within 2 weeks and maximal within 4 to 6 weeks. It does not take 6 months too see a change. The blood level of LDL cholesterol is not reduced immediately upon starting the drug; a reduction is seen within 2 weeks. Blood cholesterol is affected, specifically LDL cholesterol, not triglycerides.

Answer to Question 2

ANS: C
Before administering rosuvastatin, the nurse should review the results of the baseline liver function tests (LFTs). Statins can be used by patients with liver disease but not by those with alcoholic or viral hepatitis. Administering the drug before obtaining baseline LFT results would not allow for an accurate baseline. The patient clearly already has liver disease.
