Question

Quizplus · Accepted Answer

When ketoacids increase in the blood of a diabetic patient, the following sequence of events occurs: 1) Serum bicarbonate decreases (due to buffering of the increased acids) 2) Serum pH decreases (as H+ ions accumulate) 3) Respiration increases (as the body attempts to decrease CO2 levels and thus decrease overall acidity) 4) Urine pH decreases (as the body excretes excess H+ ions) 5) PCO₂ decreases (due to decreased renal reabsorption of bicarbonate) 6) Serum pH increases (as the body compensates for acidity by releasing bicarbonate ions into the bloodstream). Option C correctly displays the chronological order of events.
