What is the primary acid-base disturbance?
A) Metabolic acidosis — HCO3- is consumed
B) Respiratory acidosis — CO2 is retained from hypoventilation
C) Compensated metabolic alkalosis
D) Mixed respiratory and metabolic acidosis
B) Respiratory acidosis — CO2 is retained from hypoventilation
A patient presents with the following ABG results: pH 7.50, PaCO₂ 30 mm Hg, HCO₃⁻ 24 mEq/L. The
patient is experiencing anxiety and rapid breathing. What acid-base imbalance is present? Why?
A. Metabolic acidosis
B. Metabolic alkalosis
C. Respiratory acidosis
D. Respiratory alkalosis
D. Respiratory alkalosis
Rationale: The pH is elevated (>7.45), indicating alkalosis. The PaCO₂ is decreased (<38 mm Hg), indicating
a respiratory cause. The HCO₃⁻ is normal, suggesting an acute, uncompensated respiratory alkalosis.
Hyperventilation from anxiety causes excessive CO₂ elimination, leading to decreased carbonic acid and
increased pH.
A patient with prolonged vomiting has the following ABG: pH 7.48, PaCO₂ 46 mm Hg, HCO₃⁻ 32 mEq/L.
What is the primary acid-base disturbance?
A. Uncompensated respiratory alkalosis
B. Partially compensated metabolic alkalosis
C. Uncompensated metabolic acidosis
D. Fully compensated respiratory acidosis
B. Partially compensated metabolic alkalosis
A nurse is caring for a patient with respiratory alkalosis caused by hyperventilation from acute pain.
What is the most appropriate initial intervention?
A. Administer sodium bicarbonate
B. Encourage slow, controlled breathing
C. Increase oxygen flow rate
D. Prepare for mechanical ventilation
