What term is used to identify when a cell is temporarily deprived of blood supply
Infarction
Ischemia
Necrosis
Inflammation
The Correct Answer is B
Ischemia refers to the temporary deprivation of blood supply to a particular tissue or organ, resulting in reduced oxygen and nutrient delivery to cells. This can lead to cellular injury and, if prolonged, irreversible damage. Infarction, on the other hand, refers to the death of tissue due to prolonged ischemia. Necrosis is a type of cell death that occurs when cells are damaged or injured and cannot survive. Inflammation is the body's response to tissue injury or infection, and can be a result of ischemia or necrosis.

Explanation
Varicose veins occur when the valves within the veins, which normally prevent the backflow of blood, become damaged or weakened, allowing blood to pool and the veins to become enlarged and twisted. This can occur due to a variety of factors, including age, pregnancy, obesity, genetics, and prolonged periods of standing or sitting. An increase in hydrostatic pressure can contribute to the development of varicose veins, but it is not the primary cause.
Correct Answer is A
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.
