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.

Explanation
Diuretics are drugs that increase the amount of urine and salt (sodium) excreted by the kidneys. They are used to treat high blood pressure, heart failure, and edema (fluid retention). However, some diuretics can cause low levels of potassium in the blood (hypokalemia), which can lead to muscle weakness, cramps, and arrhythmias. To prevent this, a combination of diuretics acting on different parts of the kidney (such as a loop diuretic and a thiazide diuretic) may be prescribed.This way, the potassium-sparing effect of one diuretic can balance the potassium-wasting effect of the other, while still achieving a net sodium loss.
Choice A is wrong because they are not a part of the initial diuretic therapy.Combination diuretic therapy is usually reserved for patients who are resistant to or intolerant of monotherapy.
Choice C is wrong because little follow up is not needed after the initial treatment.Patients on combination diuretic therapy require close monitoring of their blood pressure, electrolytes, renal function, and weight to avoid adverse effects such as dehydration, hyponatremia, hypotension, and worsening renal function.
Choice D is wrong because they do not increase the risk of hypokalemia.As explained above, combination diuretic therapy aims to reduce the risk of hypokalemia by using a potassium-sparing diuretic along with a potassium-wasting diuretic.
Correct Answer is D
Explanation
Alpha 1 adrenergic blocking agents have a vasodilating effect and can be used for the management of hypertension. They work by blocking the alpha 1 receptors on the vascular smooth muscle, which normally cause vasoconstriction when stimulated by catecholamines like epinephrine and norepinephrine.By preventing this constriction, alpha 1 blockers lower the peripheral resistance and blood pressure
Choice A is wrong because alpha 3 adrenergic blockers do not exist.There are only two types of alpha receptors: alpha 1 and alpha 2
Choice B is wrong because alpha 2 adrenergic antagonists do not have a vasodilating effect.
They block the alpha 2 receptors, which are located presynaptically on the sympathetic nerve terminals and postsynaptically on some vascular smooth muscle cells.Alpha 2 receptors inhibit the release of norepinephrine when activated, so blocking them would increase the sympathetic activity and vasoconstriction
Choice C is wrong because alpha 1 adrenergic agonists do not have a vasodilating effect.
They stimulate the alpha 1 receptors, which cause vasoconstriction and increase the blood pressure.Alpha 1 agonists are used to treat hypotension and nasal congestion
