Questions and Answers

What is the main reason for decreasing Paco2 slowly during anesthesia?

  • To promote the excretion of bicarbonate through the kidneys
  • To facilitate the accumulation of bicarbonate in the body

  • Decreased serum sodium
  • Decreased serum magnesium
  • Decreased serum potassium
  • Decreased serum chloride (correct)
  • Which condition may stimulate renal tubules to excrete hydrogen and potentially cause metabolic alkalosis?

  • Hypokalemia (correct)
  • Hypercalcemia
  • Hypernatremia
