|
Is respiratory compensation a slow or fast response? Is it an adequate response?
|
rapid; inadequate because change in PaCO2 limits response
|
|
|
What respiratory acidosis value is too high for compensation?
|
PaCO2 >55mmHg
|
|
|
Is metabolic compensation a slow or fast response? Is this an effective response?
|
slow; very effective eventually
|
|
|
How do you calculate anion gap?
|
cations - anions
(Na+) - (Cl-) - (HCO3-) |
|
|
Hyperchloremic metabolic acidosis is what type of anion gap?
|
normal anion gap
|
|
|
What type of anion gap occurs with normochloremic metabolic acidosis?
|
increased anion gap
|
|
|
When does hyperchloremic metabolic acidosis occur? What are some examples?
|
when the disorder is bicarbonate loss; diarrhea, renal tubular acidosis, carbonic anhydrase inhibitors, Addison's disease
|
|
|
When does normochloremic metabolic acidosis occur? What are some examples?
|
occurs when non-HCl acids accumulate; lactic acidosis, ketoacidosis, salicylate, methanol, ethylene glycol, chronic renal failure
|
|
|
What occurs with distal renal tubular acidosis (RTA) Type I? Can new bicarbonate be synthesized by acidifying the urine?
|
decreased activity of collecting duct H+ ATPase; no ability to make new bicarbonate
|
|
|
What happens to urine pH and body pH with RTA Type I?
|
urine pH alkaline; body pH acidic
|
|
|
What happens with proximal RTA Type II? Can urine be acidified and new bicarbonate produced?
|
decreased activity of proximal Na+/H+ exchanger; yes both can be done
|
|
|
What happens to the urine pH in proximal RTA Type II?
|
within normal range
|
