A child with croup has an increased PCO2 a decreased pH, and a normal HCO3 blood gas value. The nurse interprets this as uncompensated:
1. Respiratory acidosis.
2. Respiratory alkalosis.
3. Metabolic acidosis.
4. Metabolic alkalosis.
1
Rationale:
1. If the pH is decreased and the PCO2 is increased with a normal HCO3, it is uncompensated respiratory acidosis. Also, croup can be a disease process that causes respiratory acidosis.
2. Respiratory alkalosis, uncompensated, has an increased pH, decreased PCO2, and normal HCO3.
3. Metabolic acidosis, uncompensated, has a decreased pH, normal PCO2, and normal HCO3.
4. Metabolic alkalosis, uncompensated, has an increased pH, normal PCO2, and increased HCO3.
