Chapter 27 : Antilipemic Drugs Questions
Question 1 of 5
A patient with coronary artery disease asks the nurse about the 'good cholesterol' laboratory values. The nurse knows that 'good cholesterol' refers to which lipids?
Correct Answer: D
Rationale: High-density lipoproteins (HDLs) are considered 'good cholesterol' due to their cardioprotective role in cholesterol recycling. LDLs and VLDLs are associated with increased cardiovascular risk, and triglycerides are not classified as 'good cholesterol.'
Question 2 of 5
A patient who has recently started therapy on a statin drug asks the nurse how long it will take until he sees an effect on his serum cholesterol. Which statement would be the nurse's best response?
Correct Answer: B
Rationale: Statins typically require 6 to 8 weeks to achieve maximum lipid-lowering effects. One week is too short, and 6 months or a year is unnecessarily long for initial effects.
Question 3 of 5
The nurse will monitor for myopathy (muscle pain) when a patient is taking which class of antilipemic drugs?
Correct Answer: B
Rationale: HMG-CoA reductase inhibitors (statins) can cause myopathy, including muscle pain, which may progress to rhabdomyolysis. Patients should report unexplained muscle pain immediately. Other classes do not commonly cause myopathy.
Question 4 of 5
When teaching a patient who is beginning antilipemic therapy about possible drug-food interactions, the nurse will discuss which food?
Correct Answer: B
Rationale: Grapefruit juice inhibits CYP3A4, which metabolizes statins, potentially increasing statin levels and toxicity risk, including rhabdomyolysis. Bran, licorice, and dairy products do not significantly interact with antilipemic drugs.
Question 5 of 5
The nurse is conducting a class about antilipemic drugs. The antilipemic drug ezetimibe works by which mechanism?
Correct Answer: D
Rationale: Ezetimibe selectively inhibits cholesterol absorption in the small intestine, reducing circulating cholesterol levels. It does not inhibit HMG-CoA reductase, prevent bile acid resorption, or activate lipins.
