Write answer in between .Q:A 35-year-old patient with a history of diabetes presents to the ED with a myriad of systemic complaints. An arterial blood gas shows serum pH 7.3, HCO3- 13 mEqL, PCO2 27 mmHg. Which of the following would you LEAST expect to observe in this patient?? A: Increased anion gap, B: Increased serum ketones, C: Increased urine output, D: Decreased respiratory rate, E: Increased serum potassium,  <response>: This is a question about metabolic acidosis in a patient with diabetes. The arterial blood gas shows an acidic pH, low bicarbonate, and normal PCO2, indicating metabolic acidosis. In metabolic acidosis, we would expect to see:- Increased anion gap due to accumulation of ketones and other acids choice A- Increased serum ketones choice B - Increased urine output as the kidneys excrete excess acid choice C- Increased respiratory rate as the body tries to compensate by blowing off CO2 choice D- Potentially increased serum potassium as H is exchanged for K choice EThe one we would least expect is a decreased respiratory rate choice D, as the body tries to compensate for the acidosis by increasing the respiratory rate to blow off CO2.D: Decreased respiratory rate
