<prompt> Please answer with one of the option in the bracket. Write reasoning in between . Write answer in between .Q:A 28-year-old woman presents to the emergency department with fever, cough, and difficulty in breathing for the last 6 hours. She also mentions that she noticed some blood in her sputum an hour ago. She denies nasal congestion or discharge, sneezing, wheezing, chest pain, or palpitation. Her past history does not suggest any chronic medical condition, including respiratory disease, cardiovascular disease, or cancer. There is no history of pulmonary embolism or deep vein thrombosis in the past. Her temperature is 38.3C 101.0F , the pulse is 108min, the blood pressure is 11680 mm Hg, and the respirations are 28min. Auscultation of her lungs reveals the presence of localized crackles over the right inframammary region. Edema is present over her left leg and tenderness is present over her left calf region. When her left foot is dorsiflexed, she complains of calf pain. The emergency department protocol mandates the use of a modified Wells scoring system in all patients presenting with the first episode of breathlessness when there is no history of a cardiorespiratory disorder in the past. Using the scoring system, the presence of which of the following risk factors would suggest a high clinical probability of pulmonary embolism?? A: Use of oral contraceptives within last 90 days, B: Intravenous drug use within last 14 days, C: History of travel of 2 hours in 30 days, D: History of surgery within the last 30 days, E: History of smoking for more than 1 year,  <response>: This is a multiple choice question about determining the clinical probability of pulmonary embolism using a modified Wells scoring system. The patient is a 28-year-old woman presenting with fever, cough, difficulty breathing, hemoptysis, tachycardia, tachypnea, crackles on lung exam, and left leg swelling and calf tenderness concerning for DVT. The question asks which risk factor from the choices would indicate a high probability of PE based on the Wells criteria. The Wells criteria assigns points for various risk factors, with a score of over 4 indicating high probability. Choice A can be eliminated, as oral contraceptive use is not part of the Wells criteria. Choice B can be eliminated, as IV drug use is also not part of the criteria. Choice C can be eliminated, as recent travel is only 1 point on the Wells score and does not indicate high probability alone. Choice D, recent surgery, is 3 points on the Wells criteria and would significantly increase the probability of PE in this setting. Choice E can be eliminated, as smoking history alone does not factor into the Wells score.D: History of surgery within the last 30 days
