A nurse is planning care for a client who requires treatment for high cholesterol. Which of the following prescriptions should the nurse expect to administer?

Chlorpromazine.

Colesevelam.

Colchicine.

Cimetidine.

Answer and Explanation

The Correct Answer is B

Colesevelam is a bile acid sequestrant that lowers cholesterol by binding to bile acids in the intestine and preventing their reabsorption into the bloodstream. Some possible explanations for the other choices are:

Choice A. Chlorpromazine is wrong because it is an antipsychotic medication that has no effect on cholesterol levels.

Choice C. Colchicine is wrong because it is an anti-inflammatory drug that is used to treat gout and other inflammatory conditions, not high cholesterol.

Choice D. Cimetidine is wrong because it is a histamine H2 receptor antagonist that reduces stomach acid production and is used to treat ulcers and gastroesophageal reflux disease (GERD), not high cholesterol.

Normal ranges for cholesterol levels vary depending on the type of cholesterol and the risk factors of the individual, but generally, total cholesterol should be less than 200 mg/dL, LDL cholesterol should be less than 100 mg/dL, HDL cholesterol should be more than 40 mg/dL for men and 50 mg/dL for women, and triglycerides should be less than 150 mg/dL.

Correct Answer is D

Explanation

A WBC count of 5,000/mm3 is low and could indicate leukopenia, a possible side effect of amitriptyline. Leukopenia increases the risk of infection and should be reported to the provider.

Choice B is wrong because a total bilirubin of 1.5 mg/dL is within the normal range of 0.3 to 1.9 mg/dL.

Choice C is wrong because a Hct of 44% is within the normal range of 37% to 48% for women and 45% to 52% for men.

Choice D is wrong because a potassium level of 4.2 mEq/L is within the normal range of 3.5 to 5.0 mEq/L.

A. Taking an HMG CoA reductase inhibitor. B. Having a 10-year history of COPD. C. Taking a high-ceiling diuretic. D. Having a prolapsed mitral valve.

Correct Answer is C

Explanation

Taking a high-ceiling diuretic predisposes this client to developing digoxin toxicity because it can cause hypokalemia (low blood potassium level), which increases the sensitivity of the heart to digoxin. Digoxin is a medicine that is used to treat heart failure or arrhythmias (abnormal heart rhythms) by increasing cardiac contractility and controlling the heart rate. Digoxin toxicity happens when there is too much digoxin in the body and it becomes harmful, causing symptoms such as nausea, vomiting, headache, confusion, vision disturbance, and irregular heartbeat.

Choice A is wrong because taking an HMG CoA reductase inhibitor (also called a statin) does not increase the risk of digoxin toxicity.

Statins are lipid-lowering medications used to prevent coronary heart disease by blocking an enzyme involved in cholesterol synthesis.

Statins do not affect the blood potassium level or the sensitivity of the heart to digoxin.

Choice B is wrong because having a 10-year history of COPD (chronic obstructive pulmonary disease) does not increase the risk of digoxin toxicity. COPD is a lung condition that causes breathing difficulties and chronic inflammation.

COPD does not affect the blood potassium level or the sensitivity of the heart to digoxin.

Choice D is wrong because having a prolapsed mitral valve does not increase the risk of digoxin toxicity.

A prolapsed mitral valve is a condition where the valve between the left atrium and left ventricle of the heart does not close properly, allowing some blood to leak back into the atrium.

A prolapsed mitral valve does not affect the blood potassium level or the sensitivity of the heart to digoxin.
