<prompt> Please answer with one of the option in the bracket. Write reasoning in between . Write answer in between .Q:A 68-year-old woman presents to the hospital for an elective right hemicolectomy. She is independently mobile and does her own shopping. She has had type 2 diabetes mellitus for 20 years, essential hypertension for 15 years, and angina on exertion for 6 years. She has a 30-pack-year history of smoking. The operation was uncomplicated. On post-op day 5, she becomes confused. She has a temperature of 38.5C 101.3F, respiratory rate of 28min, and oxygen saturation of 92 on 2 L of oxygen. She is tachycardic at 118min and her blood pressure is 11065 mm Hg. On chest auscultation, she has coarse crackles in the right lung base. Her surgical wound appears to be healing well, and her abdomen is soft and nontender. Which of the following is the most likely diagnosis?? A: Non-infectious systemic inflammatory response syndrome SIRS, B: Multiple organ dysfunction syndrome, C: Sepsis, D: Malignant hyperthermia, E: Drug-induced fever,  <response>: This is a clinical case scenario about a 68-year-old woman who develops confusion, fever, tachycardia, tachypnea, and hypoxemia on postoperative day 5 after an uncomplicated hemicolectomy. The key findings are:- Postoperative fever- Tachycardia - Tachypnea- Hypoxemia - Altered mental status confusion- Crackles on lung examThis clinical picture is most consistent with sepsis, which is defined as life-threatening organ dysfunction caused by a dysregulated host response to infection. The fever, tachycardia, tachypnea, hypoxemia and mental status changes meet criteria for sepsis. The lung crackles suggest a pulmonary source of infection. SIRS is a nonspecific inflammatory response and does not explain her clinical presentation. MODS refers to dysfunction of multiple organs, but there is no evidence for multi-organ involvement here. Malignant hyperthermia and drug fever are less likely given the timeline and lack of exposure to triggering agents.C: Sepsis
