Before a meal

The nurse is caring for a patient with chronic obstructive pulmonary disease (COPD). The patient's arterial blood gas (ABG) results reveal compensated chronic respiratory acidosis. The nurse should understand that which physiological mechanism is causing the compensated chronic respiratory acidosis in this patient? Carbon dioxide levels decrease in response to increased pH. Bicarbonate levels increase in response to increased carbon dioxide levels. Carbon dioxide levels increase in response to decreased bicarbonate levels. Bicarbonate levels increase in response to increased pH.

Bicarbonate levels increase in response to increased carbon dioxide levels.

A patient in severe respiratory distress is diagnosed with respiratory acidosis. In addition to arterial blood gases (ABGs), the patient has a chemistry panel drawn. Which clinical finding should the nurse correlate with the patient's diagnosis of acute respiratory acidosis? Potassium 4.1 mEq/L Calcium 9 mg/dL Chloride 80 mEq/L Sodium 135 mEq/L
