A child with acute asthma has a PaCO₂ of 48 mmHg,a pH of 7.31,and a normal HCO₃ blood gas value.The nurse interprets these findings as indicative of which condition? A) Metabolic acidosis B) Respiratory alkalosis C) Respiratory acidosis D) Metabolic alkalosis

Question

A) If the pH is decreased and the PaCO₂ is increased with a normal HCO₃, it is uncompensated respiratory acidosis. In addition, croup can be a disease process that causes respiratory acidosis. Uncompensated respiratory alkalosis has an increased pH, decreased PaCO₂, and normal HCO₃. Uncompensated metabolic acidosis has a decreased pH, normal PaCO₂, and normal HCO₃. Uncompensated metabolic alkalosis has an increased pH, normal PaCO₂, and increased HCO₃. B) If the pH is decreased and the PaCO₂ is increased with a normal HCO₃, it is uncompensated respiratory acidosis. In addition, croup can be a disease process that causes respiratory acidosis. Uncompensated respiratory alkalosis has an increased pH, decreased PaCO₂, and normal HCO₃. Uncompensated metabolic acidosis has a decreased pH, normal PaCO₂, and normal HCO₃. Uncompensated metabolic alkalosis has an increased pH, normal PaCO₂, and increased HCO₃.

Uncompensated respiratory alkalosis has an increased pH, decreased PaCO₂, and normal HCO₃. Uncompensated metabolic acidosis has a decreased pH, normal PaCO₂, and normal HCO₃. Uncompensated metabolic alkalosis has an increased pH, normal PaCO₂, and increased HCO₃. D) If the pH is decreased and the PaCO₂ is increased with a normal HCO₃, it is uncompensated respiratory acidosis. In addition, croup can be a disease process that causes respiratory acidosis. Uncompensated respiratory alkalosis has an increased pH, decreased PaCO₂, and normal HCO₃. Uncompensated metabolic acidosis has a decreased pH, normal PaCO₂, and normal HCO₃. Uncompensated metabolic alkalosis has an increased pH, normal PaCO₂, and increased HCO₃.
