Disturbances In Acid-Base Balances

DISTURBANCES IN ACID-BASE BALANCES

Q. 1

True is all except about Acid-Base disorder

 A

pH determined by Pco2 and HCO3

 B

Respiratory acidosis is compensated by HCO3

 C

Metabolic acidosis is compensated by Pco2

 D

Buffering may be intra & extra cellular

Q. 1

True is all except about Acid-Base disorder

 A

pH determined by Pco2 and HCO3

 B

Respiratory acidosis is compensated by HCO3

 C

Metabolic acidosis is compensated by Pco2

 D

Buffering may be intra & extra cellular

Ans. B

Explanation:

B i.e. Respiratory acidosis is compensated by HCO3


Q. 2

Uncompensated metabolic acidosis shows

 A

Increased pH with increased HCO3-

 B

Increased pH with Decreased HCO3-

 C

Decreased pH with increased HCO3-

 D

Decreased pH with decreased HCO3-

Q. 2

Uncompensated metabolic acidosis shows

 A

Increased pH with increased HCO3-

 B

Increased pH with Decreased HCO3-

 C

Decreased pH with increased HCO3-

 D

Decreased pH with decreased HCO3-

Ans. D

Explanation:

Metabolic acidosis (uncompensated) is due to decrease in HCO3-.

METABOLIC ACIDOSIS:

  • Due to decreased plasma HCO-3.
    • Results in decreased pH (acidosis).
  • Also associated with increased renal ammonia production.
    • Increased ammonia in tubule —> buffers augmented H+secretion.
