Which arterial blood gas reading does the nurse anticipate in a patient diagnosed with chronic obstructive pulmonary disease (COPD)?
1
pH 7.33, PaO 2 65 mm Hg, PaCO 2 41 mm Hg, HCO 3 - 19 mEq/L
2
pH 7.36, PaO 2 63 mm Hg, PaCO 2 52 mm Hg, HCO 3 - 32 mEq/L
3
pH 7.48, PaO 2 82 mm Hg, PaCO 2 32 mm Hg, HCO 3 - 25 mEq/L
4
pH 7.36, PaO 2 72 mm Hg, PaCO 2 30 mm Hg, HCO 3 - 18 mEq/L

The kidneys will compensate to correct for changes in blood pH that occur when the respiratory system is unhealthy (i.e., COPD) or overwhelmed by increasing the absorption of bicarbonate and excreting hydrogen ions. The reading of pH 7.36, PaO 2 63 mm Hg, PaCO 2 52 mm Hg, HCO 3 - 32 mEq/L reflects this state of compensated respiratory acidosis. A reading of pH 7.33, PaO 2 65 mm Hg, PaCO 2 41 mm Hg, HCO 3 - 19 mEq/L reflects an uncompensated metabolic acidosis. A
reading of pH 7.48, PaO 2 82 mm Hg, PaCO 2 32 mm Hg, HCO 3 -25 mEq/L reflects an uncompensated respiratory alkalosis. A reading of pH 7.36, PaO 2 72 mm Hg, PaCO 2 30 mm Hg, HCO 3 - 18 mEq/L reflects a compensated metabolic acidosis state
