A blood gas sample was collected from a patient under monitoring for an existing acid-base disorder. The sample was sent to the laboratory in an ice bath but it was found that an air bubble was present in the syringe used. The blood has also been exposed to room air for about 30 minutes. What changes have most likely occurred in the sample? A. elevated CO2 content, PCO2 decreased B. elevated C02 content, elevated PO2 and pH C. decreased CO2 content, decreased pH and PCO2 D. elevated PO2, decreased HC03

Question
40. A blood gas sample was collected from a patient under monitoring for an existing acid-base disorder. The sample was sent to the laboratory in an ice bath but it was found that an air bubble was present in the syringe used. The blood has also been exposed to room air for about 30 minutes. What changes have most likely occurred in the sample? A. elevated CO2 content, PCO2 decreased B. elevated CO2 content, elevated PO2 and pH C. decreased C02 content, decreased pH and PCO2 D. elevated PO2, decreased HCO3 41. A 31-year-old white male patient with known type 1 diabetes mellitus, end-stage renal disease secondary to diabetic nephropathy, and a history of alcoholism was admitted with acute abdominal pain in the mid-epigastrium, with a blood gas values of pH of 7.48, po2 of 121 mm Hg, O2 saturation of 99%, pCO2 of 30 mm Hg, and bicarbonate of 20 mE q/L. What is a possible compensatory mechanism? A. Decreasing H+ ion retention B. Increasing bicarbonate retention C. Increasing the respiratory rate D. Decreasing the respiratory rate 42. Determine the acid-base disorder using the following blood gas analysis results pH = 7.47 pC02 = 30 mmHg HCO3 = 25 mEq/mL A. Uncompensated respiratory alkalosis B. Uncompensated metabolic alkalosis C. Compensated respiratory alkalosis D. Compensated metabolic alkalosis
