Renal Acid Base 2 Whole Body Acid Base Balance

Question 1

Give an example of RESP acidosis

Answer 1

Chronic bronchitis
Chronic emphysema
Airway restriction
Chest injuries

Question 2

Uncompensated acidosis is shown by

Answer 2

Ph 45mmHg

Question 3

What is the compensation for RESP acidosis

Answer 3

No ec buffering
Renal system must compensate
Pco2 dives hydrogen ion secretion by kidney
Carbon dioxide retention stimulated the sec of hydrogen ions into the filtrate
Bicarbonate reabs
TA and ammonium inv

Question 4

What does RESP acidosis correction require

Answer 4

Lowering pco2 by restoration of normal ventilation

Question 5

What is rep alkalosis

Answer 5

Excessive removal of carbon dioxide by the body

Question 6

How does reps alkalosis arise

Answer 6

Low inspired po2 at high altitudes -hypoxia stim peripheral chemoreceptors hypervent lowers pco2

Hypervent

Hysterical over breathing

Question 7

Uncompensated RESP alkalosis shown by

Answer 7

Ph> 7.45

Pco2

Question 8

What is the renal compensation for RESP alkalosis

Answer 8

Excessive removal of co2 reduces hydrogen ion sec into tubule
Bicarbonate excreted releasing alkaline urine
No TA or ammonium formed so no new bicarbonate formed

Question 9

How is rep alkalosis corrected

Answer 9

Requires restoration of normal ventilation

Question 10

What is metab acidosis

Answer 10

Most common

Excess hydrogen ions form any source other than Corbin dioxide

Question 11

How can metab acidosis arise

Answer 11

Ingestion of acids or acid pouting foodstuffs
Excessive metab production hydrogen ions
Excessive loss of base from the body

Question 12

How is metab acidosis shown

Answer 12

Ph

Question 13

How is metab acidosis compensated

Answer 13

Via RESP syst

Ventilation quickly increased and more carbon dioxide blown off which caused plasma concentration to be put to normal

Question 14

How is the correction of metab acidosis

Answer 14

Filtered bicarbonate is low and readily abs
Hydrogen ion sec and TA and ammonium cause new bicarbonate form
Acid excreted in urine

Question 15

What is metabolic acidosis

Answer 15

Excessive loss of hydrogen form the body

Question 16

How can metabolic alkalosis arise

Answer 16

Loss HCl form stomach
Ingestion of alkali or alike prod foodstuffs
Aldosterone hypersecrtion

Question 17

If metab alkalosis uncomp what is shown

Answer 17

Ph> 7.35

Bicarbonate plamsa conc high

Question 18

What is the compensating for metab alkalosis

Answer 18

RESP compensation
Increased ph slows ventilation peripheral chemoreceptors
Carbon dioxide retained so the pco2 rises causing hydrogen ion conc of plasma to rise lowering the ph

Question 19

What is the correction of metab alkalosis

Answer 19

Filtered bicarbonate load so large compared to normal not all filtered bicarbonate is reabs
No TA or ammonium
Bicarbonate exported in urine
Fall back to norm

Question 20

What is RESP acidosis

Answer 20

Retention of carbon dioxide by the body

Build up in blood meaning more carbonic acid produced increasing the acidity
