C
A patient in the clinic was just given a prescription for a lipid-lowering drug by the prescriber and was told not to drink grapefruit juice. Grapefruit juice should be avoided with which class of lipid-lowering drugs?
Statins
Bile acid sequestrants
Nicotinic acid agents
Fibrates
Fibrates
Patients should not drink grapefruit juice while taking fibrates because it interferes with the metabolism (breakdown) of fibrates in the body, making them less effective. Grapefruit juice does not have to be avoided with statins, bile acid sequestrants, or nicotinic acid agents.
Which type of cholesterol-lowering drug may be prescribed with a cholesterol absorption inhibitor?
Statin
Fibrate
Bile acid sequestrant
Nicotinic acid
Statin
A statin drug may be prescribed with a cholesterol absorption inhibitor to increase the cholesterol-lowering effects.
Which statement made by a patient about when he or she takes prescribed colestipol (Colestid) granules indicates a need for further teaching?
“This medication may cause constipation.”
“I take it with 4 to 6 ounces of fruit juice or water.”
“I take it along with breakfast and my morning medications.”
“I take it 2 hours before or after my antacids.”
“I take it along with breakfast and my morning medications.”
Remind patients not to take other drugs for at least 2 hours before or 4 to 6 hours after bile acid sequestrants, because bile acid sequestrants may interfere with absorption of other drugs. Teach patients to take bile acid sequestrants with meals because they bind with cholesterol in the intestine. Constipation is a very common side effect of the drug. Tell patients to mix the powder forms of bile acid sequestrants with 4 to 6 ounces of fruit juice or water. Take tablet forms with large amounts of water (at least 12 to 16 ounces) to prevent stomach and intestinal problems such as bowel obstruction. Bile acid sequestrants should be taken 2 hours before or 2 hours after antacids. Check whether the patient is prescribed warfarin (Coumadin).
A patient is being discharged with a prescription for a lipid-lowering drug. What class of lipid-lowering drugs may require a daily vitamin supplement to be taken along with them?
Statins
Bile acid sequestrants
Cholesterol absorption inhibitors
Nicotinic acid agents
Bile acid sequestrants
The class of lipid-lowering drugs called bile acid sequestrants helps the body lose cholesterol. They also inhibit fat-soluble vitamins (A, D, E, and K), so patients may need to take a daily vitamin supplement. Statins do not affect vitamin absorption. Cholesterol absorption inhibitors do not affect vitamin absorption. Nicotinic acid agents are a special type of vitamin B and do not affect vitamin absorption.
Which point must be included in a teaching plan for a diabetic patient who has been prescribed nicotinic acid to lower cholesterol?
“The dosage of your blood glucose control drug will need to be decreased.”
“The dosage of your blood glucose control drug may need to be increased.”
“You will not need to check your glucose as often.”
“The dosage of your nicotinic acid will need to be increased.”
“The dosage of your blood glucose control drug may need to be increased.”
Nicotinic acid may increase blood glucose levels, so blood glucose control drug dosages may need to be increased.
A pediatric nurse is caring for a child prescribed a lipid-lowering medication. What lipid-lowering medication can cause intestinal obstructions in children?
Cholestyramine (Questran)
Gemfibrozil (Lopid)
Ezetimbe (Zetia)
Nicotinic acid (Niacor)
Cholestyramine (Questran)
Cholestyramine (Questran) and colestipol (Colestid) should be avoided in children because they can cause intestinal obstructions. Safe use of colesevelam (Welchol) has not been established in children. Gemfibrozil is not known to cause intestinal obstructions in children. Ezetimbe is not known to cause intestinal obstructions in children, but the safe use of cholesterol absorption inhibitors in children younger than age 10 years has not been established. Nicotinic acid is not known to cause intestinal obstructions in children; however, safe use of these drugs in children younger than age 10 years has not been established.
The nurse is performing discharge teaching for a patient who is going to take a statin medication. What symptom, indicating an adverse effect, is most important for the nurse to tell the patient and should be reported immediately to the prescriber?
Constipation
Brown urine
Bleeding
Flushing
Brown urine
Brown urine may be one symptom of rhabdomyolysis (muscle breakdown) which is an adverse effect of taking statins. Signs and symptoms include general muscle soreness, muscle pain and weakness, vomiting, stomach pain, and brown urine. The urine turns brown because small reddish-brown pieces of broken-down muscle are removed from the body through the urine. Renal failure can occur if rhabdomyolysis develops because protein released from broken-down muscle can block urine flow through the kidneys. Constipation is a symptom specific to bile acid sequestrants and does not need immediate attention. Bleeding is a symptom specific to bile acid sequestrants. Flushing is a symptom specific to nicotinic acid agents and does not need immediate attention.
The nurse is reviewing different classes of lipid-lowering drug. What class works directly on fats in the intestines?
Statins
Bile acid sequestrants
Nicotinic acid agents
Fibrates
Bile acid sequestrants
Bile acid sequestrants are a class of cholesterol-lowering drugs that bind with cholesterol in the intestine, preventing fats from being absorbed into the blood. This action then eliminates the cholesterol from the body through the stool. Statins, nicotinic acid, and fibrates do not work directly on fats in the intestines. Statins inhibit HMG CoA reductase, an enzyme that controls cholesterol production in the body, which lowers blood lipid levels by slowing the production of cholesterol and increasing the ability of the liver to remove low-density lipoprotein cholesterol from the blood. The drug action leading the lipid-lowering effects of nicotinic acid agents is not known. Fibrates activate cell lipid receptors that bind to and collect cholesterol and other lipids from the blood and break them down for elimination.
Which type of lipid-lowering drug inhibits the production of cholesterol and triglycerides by the body?
Fibrates
Bile acid sequestrants
Cholesterol absorption inhibitors
Statins
Statins
Statins lower LDL cholesterol and triglycerides by inhibiting their production by the body.
The nurse is discharging a patient with a prescription for an immediate-release form of niacin (Niacor). What instruction is most important to teach this patient?
“Call your prescriber if you have brown urine.”
“Notify your surgeon or dentist that you are taking Niacor before any surgery or dental work.”
“Watch for flushing right after taking the medication.”
“Be sure to take the medication on an empty stomach.”
“Notify your surgeon or dentist that you are taking Niacor before any surgery or dental work.”
Before any surgery or dental work, the surgeon or dentist should be notified that the patient is taking niacin because this drug can slow the clotting process and excessive bleeding can occur. These problems are made worse if the patient also takes aspirin or an NSAID daily along with a niacin. Brown urine is a symptom that is important to report when taking statin drugs, because it may indicate serious liver problem. Flushing is a normal side effect of niacin. GI side effects can be decreased by giving niacin with food.
