She reports that her father did not remember who she was yesterday, and his refrigerator was completely empty when she tried to make him lunch. She states that he was acting like himself when she visited him last week. She also notes that he has struggled with alcoholism for many years and has not seen a doctor in over two decades. She is unsure if he has any other chronic medical conditions. In the emergency room, the patients temperature is 101.2F 38.4C, pulse is 103min, respirations are 22min, and O2 saturation is 92 on room air. His BMI is 17.1 kgm2. Physical exam reveals an extremely thin and frail man who is not oriented to person, place, or time. As he is being examined, he becomes unresponsive and desaturates to 84. He is intubated and admitted to the intensive care unit for what is found to be pneumonia, and the patient is started on total parental nutrition as he is sedated and has a history of aspiration from a prior hospitalization. Two days later, physical exam is notable for new peripheral edema. Laboratory tests at that time reveal the following:Serum:Na: 133 mEqLCl-: 101 mEqLK: 2.4 mEqLHCO3-: 24 mEqLBUN: 22 mgdLGlucose: 124 mgdLCreatinine: 1.1 mgdLPhosphate: 1.1 mgdLMg2: 1.0 mgdLWhich of the following could have prevented the complication seen in this patient?? A: Slow initiation of total parenteral nutrition TPN, B: Use of enteral nutrition, C: Initiation of furosemide, D: Initiation of intermittent dialysis, E: Use of low-sugar TPN,  <response>: This is a clinical vignette about a 69-year-old man brought to the ER with confusion and later found to have pneumonia. He was started on TPN and developed peripheral edema and electrolyte abnormalities including hypokalemia, hypophosphatemia, and hypomagnesemia. The question asks what could have prevented this complication. Based on the timeline, the complication appears to be from starting TPN too rapidly in a malnourished patient. This can lead to refeeding syndrome with rapid shifts in fluids and electrolytes. Choice A suggests slowly initiating TPN which would be the best way to prevent refeeding syndrome. Choice B of using enteral nutrition would also be preferred over TPN in this patient if possible. Choices C, D, and E are not relevant to preventing refeeding syndrome.A: Slow initiation of total parenteral nutrition TPN
