This patient will be creating a respiratory alkalosis to attempt to compensate for a metabolic acidosis. Under conditions of an acidosis, the proton concentration of the blood needs to be reduced. Due to the presence of carbonic anhy- drase in the red blood cell, as carbon dioxide is exhaled, protons are removed from solution. As the concentra- tion of carbon dioxide is reduced, bicarbonate (HCO3−) reacts with a proton (H+) to form carbonic acid, which then dissociates to form water (H2O) and carbon diox- ide (CO2). These reactions are summarized in the figure below. Thus, as carbon dioxide is exhaled, the proton concentration decreases, and the acidosis is reduced. The exhalation of oxygen or nitrogen will not affect the proton levels in the blood, nor will the loss of nitrous oxide or superoxide." - :tags '("biochemistry" "amino-acids") - :suspend t) -;; -(gnosis-add-deck "Surgery") -(gnosis-add-note-mcq :deck "Surgery" - :question "A 35-year-old man is admitted with systolic blood pressure (BP) of 60 mm Hg and a heart rate (HR) of 150 bpm following a gunshot wound to the liver (Fig. 1–1).
