A patient presents with a blood pH of 7.29, bicarbonate (HCC) level of 25 mmol, and partial pressure of carbon dioxide (PaCO2) of 55 mmHg Which cause is consistent with these lab values?
Shallow and decreased breathing secondary to COPD
Hyperventilation secondary to a panic attack
Increased renal HCO2 excretion due to kidney disease
Excessive H ion loss due to severe vomiting
The Correct Answer is A
A. Shallow and decreased breathing secondary to COPD: The lab values indicate respiratory acidosis, which is characterized by a low pH (acidic), normal bicarbonate levels, and elevated PaCO2. This is consistent with hypoventilation, often seen in conditions like COPD, where shallow breathing leads to CO2 retention.
B. Hyperventilation secondary to a panic attack: Hyperventilation would cause respiratory alkalosis, not acidosis, characterized by a high pH and low PaCO2.
C. Increased renal HCO3 excretion due to kidney disease: This would lead to metabolic acidosis, not respiratory acidosis, and would typically be associated with a low bicarbonate level.
D. Excessive H+ ion loss due to severe vomiting: Severe vomiting causes metabolic alkalosis due to loss of H+ ions, not respiratory acidosis.
