Which of the following anti-lipidemic drugs are the most potent antilipidemic agents, and have proven to lower the risk of Myocardial Infarction?
Atorvastatin.
Niacin.
Gemfibrozil
Amlodipine.
The Correct Answer is A
Atorvastatin is a type of statin, which are the most potent antilipidemic agents, and have proven to lower the risk of myocardial infarction by reducing the levels of low-density lipoprotein (LDL) cholesterol and triglycerides in the blood. Statins also slightly increase the level of high-density lipoprotein (HDL) cholesterol, which is beneficial for cardiovascular health.
Choice B, niacin, is a type of nicotinic acid, which can lower LDL cholesterol and triglycerides, and increase HDL cholesterol, but it is less effective than statins and has more side effects, such as flushing, itching, and liver toxicity.
Choice C, gemfibrozil, is a type of fibric acid derivative, which can lower triglycerides and increase HDL cholesterol, but have little effect on LDL cholesterol. They are mainly used for patients with high triglyceride levels or low HDL cholesterol levels.
Choice D, amlodipine, is not an antilipidemic agent at all. It is a type of calcium channel blocker, which is used to treat hypertension and angina by relaxing the blood vessels and reducing the workload of the heart.

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.
Correct Answer is C
Explanation
This is because potassium sparing diuretics do not lower potassium levels in the blood, unlike some other types of diuretics. Potassium is an important electrolyte that helps regulate nerve and muscle functions, especially the heart. Low potassium levels can cause irregular heartbeats and other problems.Therefore, people who take diuretics should avoid foods that are high in potassium, such as bananas, oranges, tomatoes, and potatoes, unless they are taking potassium sparing diuretics.
Choice A is wrong because thiazide diuretics, such as hydrochlorothiazide, can cause low potassium levels in the blood and increase the risk of arrhythmias.
People who take thiazide diuretics may need to take potassium supplements or eat more potassium-rich foods.
Choice B is wrong because osmotic diuretics, such as mannitol, do not affect potassium levels in the blood.
They work by increasing the amount of water in the urine, but do not alter the electrolyte balance.
Osmotic diuretics are mainly used to treat brain swelling or glaucoma.
Choice D is wrong because loop diuretics, such as lasix, can also cause low potassium levels in the blood and increase the risk of arrhythmias.
People who take loop diuretics may also need to take potassium supplements or eat more potassium-rich foods.
Normal ranges for potassium in the blood are 3.5 to 5.0 millimoles per liter (mmol/L).
