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

Distended neck veins are a sign of increased central venous pressure, which can result from fluid volume excess. Fluid volume excess can also cause edema, crackles in the lungs, and increased blood pressure.

Choice A is wrong because decreased bowel sounds are not related to fluid volume excess.

Decreased bowel sounds can indicate ileus, obstruction, or peritonitis. Choice B is wrong because bilateral muscle weakness is not a sign of fluid volume excess.

Bilateral muscle weakness can be caused by electrolyte imbalances, neuromuscular disorders, or stroke.

Choice C is wrong because thready pulse is a sign of fluid volume deficit, not excess.

Thready pulse indicates poor perfusion and low cardiac output, which can result from dehydration, hemorrhage, or shock.

A. Hypomagnesemia. B. Hypocalcemia. C. Hyponatremia. D. Hypokalemia.

Correct Answer is C

Explanation

Lithium can cause hyponatremia by increasing the secretion of antidiuretic hormone and reducing the renal clearance of sodium.

Strenuous exercise can also cause hyponatremia by increasing sweat loss and fluid intake. Therefore, a client who is taking lithium and starting a new exercise program is at risk of developing hyponatremia.

Choice A is wrong because hypomagnesemia is not a common side effect of lithium or exercise.

Choice B is wrong because hypocalcemia is not a common side effect of lithium or exercise.

Choice D is wrong because hypokalemia is not a common side effect of lithium or exercise.

However, lithium can interact with some diuretics that can cause hypokalemia, so the client should avoid taking these drugs without consulting their doctor. Normal ranges for electrolytes are:

Sodium: 135-145 mmol/L

Magnesium: 0.7-1.1 mmol/L

Calcium: 2.1-2.6 mmol/L

Potassium: 3.5-5.0 mmol/L
