The nurse is planning to assess a patient's oxygen delivery status. Which of the following laboratory values are needed to complete this assessment?
1. serum potassium level
2. arterial blood gas analysis
3. blood urea nitrogen level
4. hematocrit level
2
Rationale: Oxygen delivery can be calculated by using a cardiac output measurement, serum hemoglobin analysis, and ABG analysis for SaO2 and PaO2 levels. The serum potassium level and blood urea nitrogen level are not needed to calculate a patient's oxygen delivery status. The hemoglobin level is needed and not the hematocrit level.
