The forward effects in a patient with left ventricular heart failure include (Select all that apply)

Choice A reason: Exudative fluid is not the type of fluid drained from the patient. Exudative fluid is a high-protein fluid that results from inflammation or infection of the pleura. It is usually cloudy and contains white blood cells, bacteria, or blood.

Choice B reason: Purulent fluid is not the type of fluid drained from the patient. Purulent fluid is a thick, yellow-green fluid that results from a bacterial infection of the pleura. It is also known as empyema and contains pus and dead tissue.

Choice C reason: Transudative fluid is the type of fluid drained from the patient. Transudative fluid is a low-protein fluid that results from increased hydrostatic pressure or decreased oncotic pressure in the pleural space. It is usually clear and contains few cells or organisms. It can be caused by conditions such as heart failure, cirrhosis, or nephrotic syndrome.

Choice D reason: Infectious fluid is not the type of fluid drained from the patient. Infectious fluid is a general term that can refer to any fluid that contains microorganisms that cause disease. It can be exudative or purulent, depending on the type and severity of the infection.

Choice A reason: An increase in antithrombotic substances is not a cause of atherosclerosis. Antithrombotic substances are agents that prevent or reduce the formation of blood clots. They can be used to treat or prevent atherosclerosis, not cause it.

Choice B reason: Congenital heart disease is not a cause of atherosclerosis. Congenital heart disease is a condition that is present at birth and affects the structure or function of the heart. It can be caused by genetic or environmental factors, not by atherosclerosis.

Choice C reason: Endothelial injury and inflammation are causes of atherosclerosis. Endothelial injury is the damage to the inner lining of the blood vessels, which can be caused by various factors such as high blood pressure, high cholesterol, smoking, or diabetes. Inflammation is the body's response to the injury, which involves the activation of immune cells and the release of cytokines and growth factors. These processes lead to the formation of plaque, which is composed of cholesterol, fatty substances, calcium, and other materials.

Choice D reason: High serum potassium levels are not a cause of atherosclerosis. High serum potassium levels are a condition that affects the balance of electrolytes in the blood. It can be caused by kidney disease, medication side effects, or excessive intake of potassium-rich foods. It can affect the heart rhythm and function, but it does not cause atherosclerosis.
