To decrease the risk of cardiovascular disease in patients, which measure is recommended by health care professionals?
Increase LDL Cholesterol levels.
Increase HDL cholesterol levels.
Decrease LDL Cholesterol levels.
Decrease HDL cholesterol levels.
The Correct Answer is C
LDL cholesterol is sometimes called “bad” cholesterol because it can build up on the walls of the blood vessels and cause health problems, such as heart disease and stroke. High levels of LDL cholesterol raise your risk for cardiovascular disease. Therefore, decreasing LDL cholesterol levels can lower your risk and improve your health.
Choice A is wrong because increasing LDL cholesterol levels would have the opposite effect of decreasing them. It would increase your risk for cardiovascular disease and plaque buildup in your arteries.
Choice B is wrong because increasing HDL cholesterol levels is not enough to decrease the risk of cardiovascular disease. HDL cholesterol is sometimes called “good” cholesterol because it can move LDL cholesterol from the blood to the liver, where it is broken down and removed from the body.
However, HDL cholesterol levels alone are not a good indicator of your cardiovascular health. You also need to consider your total cholesterol, LDL cholesterol and triglyceride levels.
Choice D is wrong because decreasing HDL cholesterol levels would also increase your risk for cardiovascular disease. HDL cholesterol helps to lower LDL cholesterol levels and protect your blood vessels from plaque buildup.
Therefore, decreasing HDL cholesterol levels would reduce this protective effect and make you more vulnerable to heart disease and stroke.
The ideal ranges for cholesterol levels are as follows:
• Total cholesterol: below 200 mg/dL
• LDL cholesterol: less than 100 mg/dL
• HDL cholesterol: above 40 mg/dL for men and above 50 mg/dL for women
You can lower your LDL cholesterol levels and increase your HDL cholesterol levels by making healthy lifestyle changes, such as eating a balanced diet, exercising regularly, quitting smoking, managing stress and taking medication if prescribed by your doctor.

Correct Answer is C
Explanation
Digibind is the trade name forantidigoxin, which is an antibody made up of anti-digoxin immunoglobulin fragments.It is thespecific antidoteto digoxin toxicity, which can occur even when the serum digoxin concentration is within the therapeutic range.Digoxin toxicity causes anorexia, nausea, vomiting, neurological symptoms and arrhythmias.
Choice A, Protamine sulfate, is wrong because it is the antidote for heparin overdose, not digoxin toxicity.
Protamine sulfate reverses the anticoagulant effect of heparin by binding to it and forming a stable complex.
Choice B, Acetylcysteine, is wrong because it is the antidote for acetaminophen overdose, not digoxin toxicity.
Acetylcysteine replenishes glutathione, which is depleted by acetaminophen metabolites that cause hepatotoxicity.
Choice D, Vitamin K, is wrong because it is the antidote for warfarin overdose, not digoxin toxicity.
Vitamin K restores the synthesis of clotting factors that are inhibited by warfarin.
Normal ranges for serum digoxin concentration are 0.6 to 1.2 nanomol/L (0.5 to 0.9 nanograms/mL) for heart failure and unknown for atrial fibrillation without heart failure.
Normal ranges for serum potassium level are 3.5 to 5.0 mmol/L and for serum magnesium level are 0.7 to 1.0 mmol/L.
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.
