renal 7 Acid base imbalances: part 1

?

1. when Describing acid base imbalances, you refer to origin and nature. Nature refers to what

  • The nature is simply how pH is affected, either down (acidosis direction) or up (alkalosis direction). In addition, metabolic acidosis can be further characterised and diagnosed by reporting the anion gap, resulting in either a high anion gap metabolic ac
  • to the cause of the imbalance in terms of either: a change in carbon dioxide level (i.e. respiratory origin, typically involving either hypo- or hyperventilation); or change in bicarbonate level for any reason (i.e. metabolic origin, typically involving changes in blood acid load and corresponding loss/gain in bicarbonate or alternatively e.g. the ingestion of bicarbonate).

  • The nature is simply how pH is affected, either down (acidosis direction) or up (alkalosis direction). In addition, metabolic acidosis can be further characterised and diagnosed by reporting the anion gap, resulting in either a high anion gap metabolic acidosis (HAGMA) or normal (or non-) anion gap metabolic acidosis (NAGMA).

3. what is The anion gap is numerically defined as?

  • difference between the (typically serum) concentration of prevalent cations and anions
  • difference between the (typically serum) concentration of prevalent cations and bicarbonate
  • difference between the (typically serum) concentration of prevalent bicarbonate and anions

4. if origin of acid base imbalance is respiratory what is the term affected, compensation, and correction

  • term affected- pCO2, compensation- renal, correction-respiratory
  • term affected- HCO3, compensation- renal, correction-respiratory
  • term affected- pCO2, compensation- respiratory, correction-renal
  • term affected- pCO2, compensation- resp, correct-renal

5. compensation of acid base imbalance is reachieving blood pH of 7.4
, select the incorrect method

  • altered renal function (carbonate absorption + generation) in RENAL COMPENSATION
  • altered lung function (respiration rate + CO2 venting) in RESPIRATORY COMPENSATION
  • altered renal function (bicarbonate reabsorption + generation) in RENAL COMPENSATION
