A patient is going to be assessed for oxygen consumption level. The nurse realizes that which of the following will be used to make this assessment?
1. serum lactate level
2. hemoglobin level
3. serum potassium level
4. creatinine level
1
Rationale: Current methods of assessing oxygen consumption are limited to indirect measurement techniques including measurement of serum lactate levels, base deficit, and mixed venous oxygen saturation monitoring therefore the serum lactate level will be used to assess the patient's oxygen consumption level. The other choices are not used to assess oxygen consumption levels.
