A morbidly obese adult patient who smokes 2 packs of cigarettes daily was admitted for a major abdominal surgery. Postoperatively, the most appropriate laboratory value that a clinical nurse specialist should monitor that would reflect the patient’s respiratory status is the:
  1. O2 saturation
  2. PO2
  3. Hemoglobin
  4. PCO2
Explanation
Answer - A - Postoperatively, the most appropriate laboratory value that a clinical nurse specialist should monitor that would reflect the patient’s respiratory status is oxygen saturation. Oxygen saturation is a measure of the relationship between hemoglobin and oxygen. It measures the amount of oxygen available to tissues and provides a pulmonary assessment for patients at risk for hypoxia.
