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

Question 2

The patient has been diagnosed with multiple sclerosis, a disease that reduces the amount of available adenosine triphosphate (ATP) in the body.
 
  The nurse recognizes that this reduction in ATP is caused by the impact of the disease on what part of the cell? A) Cell neuron
  B) Endoplasmic reticulum
  C) Golgi bodies
  D) Mitochondria

Answer to Question 1

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.

Answer to Question 2

D
Feedback:
The mitochondria are rod-shaped power plants within each cell that produce energy in the form of ATP, which allows the cell to function. Inadequate production of ATP would indicate damage to the functioning of the mitochondria. The neuron, endoplasmic reticulum, and Golgi bodies do not produce ATP.
