Patients taking which cholesterol-lowering agent may require supplements of fat-soluble vitamins A, D, E, and K?

Nicotinic acid.

Nitroglycerin.

Bile acid-binding resins.

Beta Blockers.

Answer and Explanation

The Correct Answer is C

Bile acid-binding resins are cholesterol-lowering agents that bind to bile acids in the intestine and prevent their reabsorption. This reduces the amount of bile acids available for cholesterol synthesis in the liver, which lowers the levels of LDL cholesterol in the blood. However, bile acids are also needed for the absorption of fat-soluble vitamins A, D, E, and K. Therefore, patients taking bile acid-binding resins may require supplements of these vitamins to prevent deficiency.

Choice A is wrong because nicotinic acid, or niacin, is a B vitamin that can lower cholesterol by limiting the production of fats in the liver. It does not affect the absorption of fat-soluble vitamins.

Choice B is wrong because nitroglycerin is not a cholesterol-lowering agent, but a vasodilator that relaxes the blood vessels and improves blood flow. It has no effect on fat-soluble vitamin absorption.

Choice D is wrong because beta blockers are not cholesterol-lowering agents, but drugs that lower blood pressure and heart rate by blocking the effects of adrenaline. They have no effect on fat-soluble vitamin absorption.

Correct Answer is D

Explanation

Taking niacin with an NSAID such as ibuprofen can reduce flushing, the most common adverse effect of niacin therapy. Flushing is a side effect of taking large doses of niacin (vitamin B3) supplements.It happens when the niacin causes the small blood vessels in your skin to dilate so more blood can rush through.Flushing can cause skin redness, warmth, itching, tingling, or burning sensations.

Choice A is wrong because taking niacin before starting daily activities can increase the risk of flushing and interfere with your routine.Flushing usually occurs within 15 to 30 minutes of taking niacin and lasts for about an hour.

Choice B is wrong because taking niacin with a sedative can increase the risk of liver damage, especially if the sedative is acetaminophen (Tylenol).Niacin can also cause liver problems at high doses, so combining it with another liver-toxic drug is not advisable.

Choice C is wrong because taking niacin with grapefruit juice can increase the risk of side effects, such as low blood pressure, dizziness, or fainting.Grapefruit juice can interfere with the metabolism of some drugs, including niacin, and make them more potent or toxic.

Normal ranges for niacin intake vary depending on age and gender.The recommended dietary allowance (RDA) for adult males is 16 mg per day and for adult females is 14 mg per day.Higher doses of niacin may be prescribed by a doctor to treat high cholesterol or other conditions, but they should be taken under medical supervision and with caution.

A. Protamine sulfate. B. Acetylcysteine. C. Antidigoxin. D. Activated charcoal.

Correct Answer is C

Explanation

Antidigoxin is an antidote for digoxin toxicity that binds and inactivates digoxin, a cardiac glycoside that can cause life-threatening arrhythmias, hyperkalemia, and other symptoms when overdosed.Antidigoxin is also known as digoxin immune Fab or DIGIFab.

Choice A, protamine sulfate, is wrong because it is an antidote for heparin, an anticoagulant that can cause bleeding when overdosed.

Choice B, acetylcysteine, is wrong because it is an antidote for acetaminophen, a painkiller that can cause liver damage when overdosed.

Choice D, activated charcoal, is wrong because it is a nonspecific adsorbent that can reduce the absorption of some drugs or poisons from the gastrointestinal tract, but it is not effective for digoxin toxicity.
