The patient asks the nurse what atorvastatin (Lipitor), newly prescribed, will do. What expected outcome will the nurse describe?
A) Decrease in serum cholesterol only
B) Decrease in serum cholesterol and low density lipoprotein (LDL) levels
C) Decrease in sitosterol and serum cholesterol
D) Decrease in campesterol and LDL levels
B
Feedback:
Atorvastatin is a beta-hydroxy-beta-methylglutaryl coenzyme A reductase inhibitor and should lower serum cholesterol and LDL levels as well as prevention of a first myocardial infarction and slow the progression of coronary artery disease. A decrease in serum cholesterol alone would result from the use of a bile acid sequestrant. A cholesterol absorption inhibitor would also decrease sitosterol and campesterol levels as well as decrease levels of serum cholesterol and LDL.
