The nurse is reviewing the results of laboratory tests conducted on a client admitted with a respiratory disorder. Which laboratory finding would be most significant for this client?
A) Hemoglobin level 12 mg/dL
B) Oxygen saturation 96%
C) Serum sodium 140 mg/dL
D) Blood pH 7.32
Answer: D
Normal blood pH is 7.35-7.45. A decreased pH indicates that the client is experiencing acidosis, which indicates an alteration in oxygenation. The serum sodium does not impact the oxygen capacity of the body. The hemoglobin level affects the amount of oxygen that can be carried in the blood; however, the value is within normal limits. Oxygen saturation of 96% is within normal limits.
