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.

Explanation
Orthostatic hypotension is a drop in blood pressure that occurs when a person stands up from a sitting or lying down position. To check for orthostatic hypotension, the nurse typically takes the patient's blood pressure and heart rate while the patient is lying down, then has the patient stand up for a few minutes and takes the blood pressure and heart rate again. If the blood pressure drops significantly (usually a drop of 20 mm Hg or more) and the heart rate increases, it may indicate orthostatic hypotension.
Correct Answer is B
Explanation
IgE is the immunoglobulin associated with allergic reactions and is often elevated in patients with asthma. When a person with asthma is exposed to an allergen, their IgE levels increase, leading to the release of inflammatory chemicals such as histamine, which can cause bronchoconstriction and other symptoms of asthma.
IgA: This is an immunoglobulin that plays a role in the immune system's defense against infections. It is mainly found in the mucous membranes of the respiratory and gastrointestinal tracts.
IgG: This is the most abundant immunoglobulin in the bloodstream and plays a role in providing immunity against bacterial and viral infections. It can also cross the placenta and provide passive immunity to a developing fetus.
IgM: This is the first immunoglobulin produced in response to an infection and plays a role in the body's defense against bacterial and viral infections. It is found primarily in the bloodstream.
