In this task, you are given a multiple-choice question about healthcare. Answer the question based on your information and classify your answers into '1', '2', '3', and '4'.
question:
Question: Except in patients whose chronic renal failure is due to diabetic nephropathy or tubulointerstitial nephropathy, the arterial blood gas pattern that you would expect to find in a patient with chronic renal failure would be: 
 Options:  <1> pH 7.30, HCO3 18 mEq / L, Cl 116 mg / dL, because metabolic acidosis with normal anion gap is characteristic. <2> pH 7.46, HCO3 18 mEq / L, Cl 116 mg / dL, because hyperchloremic metabolic alkalosis is characteristic. <3> pH 7.456, HCO3 18 mEq / L, Cl 100 mg / dL, because metabolic acidosis with increased anion gap is characteristic. <4> pH 7.46, HCO3 30 mEq / L, Cl 90 mg / dL, because metabolic alkalosis with normal anion gap is characteristic. <5> pH 7.45, HCO3 23 mEq / L, Cl 100 mg / dL, because metabolic alkalosis with normal anion gap is characteristic.
answer:
3


question:
Question: What is cardiac output? 
 Options:  <1> The volume of blood that leaves the heart per unit of time (ml / min or l / min). <2> The complete heartbeat constituted by contraction (systole) and relaxation (diastole) in both atria and in both ventricles measured in time (sec). <3> The blood that remains in the heart when the pressure gradient determines the distension of the cardiac fibers. <4> The power gradient of the contraction, also called contractility. <5> The ventricular volume that remains constant.
answer:
1
