Questions and Answers

How do the kidneys compensate for acidosis in respiratory acidosis?

  • By increasing NaHCO3 levels (correct)
  • By decreasing pH
  • By decreasing the NaHCO3 to H2CO3 ratio
  • By decreasing PCO2 levels

What characterizes metabolic acidosis caused by a high protein diet?

  • Decreased production of acids
  • Lowered oxidation of proteins
  • Decreased production of lactic acid
  • Increased oxidation of proteins producing large amounts of acids (correct)

What is the ideal ratio between NaHCO3 and H2CO3 during compensation for acidosis in respiratory acidosis?

  • 15:1
  • 10:1
  • 5:1
  • 20:1 (correct)
