The nurse is preparing a client for discharge with a medical prescription for the HMG-CoA inhibitor, lovastatin [Mevacor]. Which statements from the client demonstrate a clear understanding of the teaching provided by the nurse?
Take medication at night and avoid grapefruit juice.
Take medication on an empty stomach before breakfast.
Avoid dietary intake of dark, leafy greens.
Increase intake of potassium-rich foods and alcohol.
The Correct Answer is A
A. Lovastatin is most effective when taken at night because cholesterol synthesis primarily occurs during sleep. Grapefruit juice should be avoided as it can increase the drug's concentration, leading to potential toxicity.
B. Lovastatin should be taken with food, preferably in the evening, to enhance absorption and effectiveness.
C. Dark, leafy greens are not contraindicated with lovastatin; they do not interfere with the medication’s action.
D. Alcohol intake should be limited while on statins due to the increased risk of liver damage, and there is no need to increase potassium-rich foods specifically.
