Question 1

A nurse is providing patient education about colesevelam (Welchol), a bile acid sequestrant. Which statement made by the patient demonstrates a need for further teaching?&#10;A) &#34;Colesevelam will reduce my levels of low-density lipoprotein.&#34;&#10;B) &#34;Colesevelam will augment my statin drug therapy.&#34;&#10;C) &#34;I will not have to worry about having as many drug interactions as I did when I took cholestyramine.&#34;&#10;D) &#34;I cannot take digoxin while on this medication.&#34;

Accepted Answer

Digoxin can be taken 1 hour before or 4 hours after taking a bile acid sequestrant. Colesevelam reduces the LDL cholesterol level, which is one of its therapeutic uses. Colesevelam augments statin therapy. Colesevelam does not significantly interact with or reduce the absorption of statins, digoxin, warfarin, or most other drugs.

Question 2

During discharge instruction, a nurse wants to assess a patient's understanding of treatment with cholestyramine (Questran). Which statement made by the patient best demonstrates a need for additional teaching?

A) "I will take cholestyramine (Questran) 1 hour before my other medications."
B) "I will increase fluids and fiber in my diet."
C) "I will weigh myself weekly."
D) "I will have my blood pressure checked weekly."

"I will weigh myself weekly."

Accepted Answer

Patients need not weigh themselves weekly when taking cholestyramine. Cholestyramine should be taken at least 1 hour before other medications. When taken with other medications, cholestyramine can inhibit the absorption of the other drugs. Constipation is the principal complaint with cholestyramine. It can be minimized by increasing dietary fiber and fluids. Regular blood pressure checks are a good idea. The patient is taking cholestyramine because of high cholesterol, which contributes to hypertension.

Question 3

A nurse is providing discharge teaching instructions for a patient taking cholestyramine (Questran). Which statement made by the patient demonstrates a need for further teaching?&#10;A) &#34;I will take warfarin (Coumadin) 1 hour before my medicine.&#34;&#10;B) &#34;I will increase the fluids and fiber in my diet.&#34;&#10;C) &#34;I can take cholestyramine with my hydrochlorothiazide.&#34;&#10;D) &#34;I will take digoxin 4 hours after taking the cholestyramine.&#34;

Accepted Answer

Drugs known to form complexes with the sequestrants include thiazide diuretics, such as hydrochlorothiazide, digoxin, warfarin, and some antibiotics. To reduce the formation of sequestrant-drug complexes, oral medication should be administered either 1 hour before the sequestrant or 4 hours after. Further teaching is needed. Warfarin should be taken 1 hour before or 4 hours after cholestyramine. Adverse effects of Questran are limited to the gastrointestinal (GI) tract. Constipation, the principal complaint, can be minimized by increasing dietary fiber and fluids. Digoxin should be taken 1 hour before or 4 hours after cholestyramine.

Question 4

A prescriber has ordered rosuvastatin (Crestor) for a patient with non-alcoholic-related cirrhosis. Which intervention would be most appropriate for the nurse before administration of this drug?&#10;A) Question the order, because rosuvastatin is contraindicated in patients with liver disease.&#10;B) No intervention is necessary; just administer the drug as ordered.&#10;C) Review the baseline liver function test results.&#10;D) Assess the patient for liver disease.

Accepted Answer

Before administering rosuvastatin, the nurse should review the results of the baseline liver function tests (LFTs). Statins can be used by patients with liver disease but not by those with alcoholic or viral hepatitis. Administering the drug before obtaining baseline LFT results would not allow for an accurate baseline. The patient clearly already has liver disease.

Question 5

A patient presents to the clinic with complaints of muscle aches, muscle pain, and weakness. Upon review of the individual's medications, the nurse notes that the patient is concurrently taking gemfibrozil (Lopid) and atorvastatin (Lipitor). The nurse should assess the patient for the development of:

A) migraines.
B) hypothyroidism.
C) myopathy.
D) heart failure.

Accepted Answer

When gemfibrozil and a statin are taken concurrently, the risk of myopathy is increased more than with either agent alone. Migraines, hypothyroidism, and heart failure are not drug-to-drug interactions.

Question 6

An Asian patient comes to the clinic. Upon assessment, the nurse notes a slight yellow tint to the skin and sclera, edema, and hepatomegaly. The drug history reveals that the patient has been taking rosuvastatin (Crestor) for 6 months. The nurse is concerned, because rosuvastatin (Crestor) has been shown to do what?

A) Cause renal and pancreatic toxicity specifically in Asian patients
B) Cause renal failure
C) Create myoglobin in the urine
D) Reach levels twice as high in Asians as in Caucasians, resulting in a greater chance of hepatotoxicity

Accepted Answer

Rosuvastatin reaches abnormally high levels in people of Asian heritage. Consequently, hepatotoxicity may occur more often in Asian patients because of the high level of the drug in the blood. Rosuvastatin does not cause renal or pancreatic toxicity. Rosuvastatin does not cause renal failure. Rosuvastatin does not create myoglobin in the urine.

Question 7

A nurse is reviewing a patient's medications and realizes that gemfibrozil (Lopid) and warfarin (Coumadin) are to be administered concomitantly. This finding concerns the nurse, who is aware that the _____ will be _____.

A) level of gemfibrozil; increased
B) level of gemfibrozil; reduced
C) anticoagulant effects; increased
D) anticoagulant effects; reduced

Accepted Answer

Gemfibrozil displaces warfarin from the plasma albumin, thereby increasing anticoagulant effects. The level of gemfibrozil will not be increased or decreased. The anticoagulation effects will not be reduced, because free-floating drug is present in the system; the dosage of warfarin may need to be reduced.

Question 8

Lovastatin (Mevacor) is prescribed for a patient for the first time. The nurse should provide the patient with which instruction?&#10;A) &#34;Take lovastatin with your evening meal.&#34;&#10;B) &#34;Take this medicine before breakfast.&#34;&#10;C) &#34;You may take lovastatin without regard to meals.&#34;&#10;D) &#34;Take this medicine on an empty stomach.&#34;

Accepted Answer

Patients should be instructed to take lovastatin with the evening meal. Statins should be taken with the evening meal, not before breakfast. Statins should not be administered without regard to meals and should not be taken on an empty stomach.

Question 9

A patient with a history of angina and hypertension is being started on nicotinic acid (Niacin). The nurse is providing patient education. What statement made by the patient demonstrates a need for further teaching?

A) "I will take Tylenol with my medication to reduce the inflammatory effects."
B) "I will be cautious taking this medication, because I have mild liver damage."
C) "I will take an aspirin 30 minutes before my niacin to reduce flushing."
D) "This medication will lower my triglyceride levels."

Accepted Answer

Intense flushing of the face, neck, and ears occurs in practically all patients taking nicotinic acid in pharmacologic doses. Tylenol will not reduce the flushing or inflammatory effects of the medication; further patient teaching is required. The flushing reaction diminishes in several weeks and can be attenuated by taking 325 mg of aspirin 30 minutes before each dose. Nicotinic acid is hepatotoxic; therefore, the patient should be taught to have the liver enzymes checked and to self-monitor for signs and symptoms. Nicotinic acid reduces low-density lipoprotein (LDL) cholesterol and triglyceride (TG) levels.

Question 10

A patient who recently started therapy with an HMG-COA reductase inhibitor asks the nurse, &#34;How long will it take until I see an effect on my LDL cholesterol?&#34; The nurse gives which correct answer?&#10;A) &#34;At least 6 months is required to see a change.&#34;&#10;B) &#34;A reduction usually is seen within 2 weeks.&#34;&#10;C) &#34;Blood levels normalize immediately after the drug is started.&#34;&#10;D) &#34;Cholesterol will not be affected, but triglycerides will fall within the first week.&#34;

Accepted Answer

Reductions in LDL cholesterol are significant within 2 weeks and maximal within 4 to 6 weeks. It does not take 6 months too see a change. The blood level of LDL cholesterol is not reduced immediately upon starting the drug; a reduction is seen within 2 weeks. Blood cholesterol is affected, specifically LDL cholesterol, not triglycerides.
