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
Acute respiratory distress syndrome (ARDS) is the most likely diagnosis based on the patient's symptoms and test results. ARDS is a serious condition that can develop in response to a variety of lung injuries, including pneumonia, sepsis, and trauma. The hallmark of ARDS is diffuse alveolocapillary injury, which leads to decreased lung compliance, hypoxemia, and respiratory distress. The symptoms of ARDS typically develop rapidly and include dyspnea, rapid, shallow breathing, inspiratory crackles, and hypoxemia. Treatment for ARDS typically involves supportive care, including oxygen therapy, mechanical ventilation, and treatment of the underlying cause of the lung injury.
Correct Answer is A
Explanation
Cystic fibrosis is a genetic disorder caused by mutations in the CFTR gene, which is inherited in an autosomal recessive manner. This means that a child must inherit two copies of the mutated gene (one from each parent) to develop the disorder. If only one parent carries a copy of the mutated gene, their children will not develop cystic fibrosis but may be carriers of the gene.
