Which elevated value may be protective of the development of atherosclerosis
Very low density lipoproteins VLDL
Low density lipoprotein LDL
High density lipoprotein HDL
Triglycerides TGs
The Correct Answer is C
Atherosclerosis is a disease in which fatty deposits (plaques) build up in the walls of arteries, leading to narrowing and reduced blood flow. Elevated levels of certain lipids, including low density lipoprotein (LDL) cholesterol and triglycerides, are well-established risk factors for the development of atherosclerosis. 
In contrast, high density lipoprotein (HDL) cholesterol has been shown to have a protective effect against atherosclerosis. HDL is often referred to as "good cholesterol" because it helps to transport excess cholesterol from peripheral tissues (including the walls of arteries) back to the liver for processing and excretion. HDL also has anti-inflammatory and antioxidant properties that may help to reduce the risk of atherosclerosis.
In general, higher levels of HDL cholesterol are associated with a lower risk of cardiovascular disease and atherosclerosis. However, the protective effect of HDL may vary depending on other factors such as smoking, obesity, and diabetes. It is important to maintain a healthy balance of lipids in the bloodstream, including a high level of HDL and low levels of LDL and triglycerides, in order to reduce the risk of atherosclerosis and other cardiovascular diseases.

Correct Answer is B
Explanation
The correct answer is B. Systolic pressure less than 120 mmHg and diastolic pressure less than 80 mmHg is considered normal blood pressure in adults according to current guidelines. A systolic pressure between 140-150 mmHg (option A) would be classified as stage 1 hypertension, while a systolic pressure greater than 140 mmHg and diastolic pressure of 100 mmHg (option D) would be classified as stage 2 hypertension. A systolic pressure less than 100 mmHg regardless of diastolic pressure (option C) would be considered low blood pressure.
Correct Answer is C
Explanation
When the left ventricle is unable to pump blood effectively, blood backs up into the lungs, leading to pulmonary congestion and edema. This can cause symptoms such as shortness of breath, coughing, and wheezing. Decreased venous pressure and hyperoxygenation are not typically associated with left ventricular failure. Bradycardia may occur in some cases, but it is not a defining feature of left ventricular failure.
