The nurse is reviewing the results of laboratory tests conducted on a client admitted with a respiratory disorder. The laboratory finding that is the most significant for this client would be:
1. Blood pH 7.40.
2. Serum sodium 140 mg/dL.
3. Hemoglobin level 8.3.
4. Oxygen saturation 96%.
3. Hemoglobin level 8.3.
Rationale:
The hemoglobin level affects the amount of oxygen that can be carried in the blood. The low level suggests the client does not have enough red blood cells to provide adequate oxygen for the body. The blood pH of 7.40 is within normal limits. Serum sodium does not impact the oxygen capacity of the body. Oxygen saturation of 96% is within normal limits.
