What would be seen with respiratory acidosis given the following lab values: pH: 7.26, paCO2: 50, HCO3: 26?

What would be seen with respiratory acidosis given the following lab values: pH: 7.26, paCO2: 50, HCO3: 26?

• A. Hyperkalemia
• B. Hypocalcemia
• C. Hypercalcemia
• D. Normal calcium levels

Answer: (C)

In the context of respiratory acidosis, the lab values indicate a decreased pH of 7.26, an elevated partial pressure of carbon dioxide (paCO2) at 50 mmHg, and a normal bicarbonate (HCO3) level of 26 mEq/L. The primary disturbance here is the respiratory acidosis, characterized by an increase in paCO2, leading to an accumulation of carbonic acid in the blood and a resulting drop in pH. In respiratory acidosis, the body compensates for the acidosis through various mechanisms, one of which involves potassium metabolism. Hyperkalemia, or elevated potassium levels, often occurs concurrently due to the effect of acidosis on potassium movement across cell membranes. In acidosis, hydrogen ions move into cells in exchange for potassium ions moving out, which can lead to increased serum potassium levels. As for the calcium levels, there is not a direct link between respiratory acidosis and significant changes in calcium homeostasis. Typically, variations in calcium levels—such as hypocalcemia or hypercalcemia—are more associated with metabolic disturbances rather than respiratory issues. Therefore, the most pertinent consequence of respiratory acidosis in the context of electrolyte balance would be hyperkalemia rather than alterations in calcium
