D. Respiratory acidosis with full compensation

2. pH 7.48 PaCO2 42 HCO3 30

A. Metabolic acidosis without compensation

B. Respiratory alkalosis with partial compensation

C. Respiratory alkalosis with full compensation

D. Metabolic alkalosis without compensation

3. pH 7.38 PaCO2 38 HCO3 24

A. Respiratory alkalosis

B. Normal

C. Metabolic Alkalosis

D. None of the above

4. pH 7.21 PaCO2 60 HCO3 24

A. Normal

B. Respiratory acidosis without compensation

C. Metabolic acidosis with partial compensation

D. Respiratory acidosis with complete compensation

5. pH 7.48 PaCO2 28 HCO3 20

Answer 1

1.pH 7.33 PaCO2 60 HCO3 34

C. Respiratory acidosis with partial compensation.

[His Paco2 is inferior than standard, flickering the lungs' effort to recompense. Since pH is irregular, knowing recompense isn't comprehensive.]

2.pH 7.48 PaCO2 42 HCO3 30

D. Metabolic alkalosis without compensation

[Occurs mostly in the lungs, which recollect carbon dioxide concluded gentler conscious, or hypo-ventilation - respiratory recompense.]

3.pH 7.38 PaCO2 38 HCO3 24

B. Normal

[The standard variety for pH is 7.35 to 7.45. As the pH reductions, it suggests acidosis, although if the pH upsurges, it suggests alkalosis.]

4.pH 7.21 PaCO2 60 HCO3 24

B. Respiratory acidosis without compensation

[Comprehensive kidney recompense might take numerous days and necessitates usual kidney purpose and intravascular size position.]

5.pH 7.48 PaCO2 28 HCO3 20

A. Respiratory alkalosis with partial compensation

[Afterward 2-7 hours, respiratory alkalosis is renal recompense commences by lessening bicarbonate re-absorption.]
