Interpret the following ABG:
PH 7.51
Pa02 88
PaC02 32
Bicarb (HC03-) 26
Sa02 95%
respiratory acidosis
respiratory alkalosis
metabolic acidosis
metabolic alkalosis
The Correct Answer is B
A. Respiratory acidosis: Respiratory acidosis would present with a low pH (below 7.35) and a high PaCO2 (above 45 mmHg).
B. Respiratory alkalosis: This ABG shows a high pH (7.51), low PaCO2 (32 mmHg), and normal HCO3- (26 mEq/L), indicating respiratory alkalosis, typically due to hyperventilation.
C. Metabolic acidosis: Metabolic acidosis would present with a low pH and low HCO3-, but in this case, the HCO3- is normal.
D. Metabolic alkalosis: Metabolic alkalosis would show a high pH and high HCO3-, but the HCO3- in this ABG is normal.

Correct Answer is ["A","D"]
Explanation
A. HAV: Hepatitis A is spread via the fecal-oral route, often through contaminated food or water.
B. HCV: Hepatitis C is primarily spread through blood-to-blood contact, not the fecal-oral route.
C. HDV: Hepatitis D is spread through blood contact and requires Hepatitis B for replication.
D. HEV: Hepatitis E is spread through the fecal-oral route, similar to Hepatitis A.
E. HBV: Hepatitis B is spread through blood, sexual contact, and perinatal transmission, not the fecal-oral route.
Correct Answer is C
Explanation
A. Partially compensated Metabolic Alkalosis: This is incorrect because the pH is within normal limits (7.35-7.45), and the elevated PaCO2 and bicarbonate suggest a respiratory issue rather than a metabolic one.
B. Fully compensated Metabolic Acidosis: This is incorrect because the primary disturbance is respiratory, not metabolic. A compensated metabolic acidosis would typically show a low PaCO2 as compensation.
C. Fully compensated Respiratory Acidosis: Correct. The pH is within the normal range, indicating full compensation. The elevated PaCO2 and bicarbonate reflect a chronic respiratory acidosis that has been compensated by the kidneys.
D. Partially compensated Respiratory Alkalosis: This is incorrect because in respiratory alkalosis, the PaCO2 would be low, not high.
