Question

The “excess” of one substance needed to correct this quantity is often between -2 and +2 and is reported on ABG panels, which show this quantity first. (15[1])Winters’s formula calculates the expected respiratory compensation in one disturbance to this quantity. Kussmaul breathing may compensate (15[1])for a high anion gap disturbance in this quantity, which can result from the overproduction of (*) beta-hydroxybutyrate in diabetics. Diarrhea and vomiting cause hypochloremic, hypokalemic derangements in this quantity, whose [emphasize] decrease reduces hemoglobin’s affinity for oxygen in the Bohr (10[1])effect. Metabolic disturbances to this quantity are offset by adjusting CO2 levels since this quantity is regulated (10[1])by carbonic anhydrase. For 10 points, the bicarbonate buffer system helps maintain what physiological quantity around 7.4? ■END■

ANSWER: blood pH [accept anion gap until read; prompt on pH; prompt on acidity, basicity, or alkalinity; prompt on PaCO2 or carbon dioxide partial pressure by asking “what other quantity does that indicate a change in?”]
