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.

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 A
Explanation
A. Hypertension: This is not a cause of high-output heart failure. Hypertension typically leads to low-output heart failure due to increased afterload, which causes the heart to work harder.
B. Severe anemia: Severe anemia causes high-output heart failure because the body compensates for the decreased oxygen-carrying capacity by increasing cardiac output.
C. Sepsis: Sepsis can lead to high-output heart failure as the body attempts to maintain perfusion in the face of widespread vasodilation.
D. Hyperthyroidism: Hyperthyroidism increases metabolic demands, which can cause high-output heart failure as the heart attempts to meet the increased needs.
