A nurse is caring for a client who is 2 hr postoperative. Which of the following findings should the nurse report to the provider?

A wound dressing that is saturated with sanguinous (bright red) drainage after already being reinforced indicates active hemorrhage and must be reported to the provider immediately — this is a surgical emergency. Urine output of 50 mL/hr exceeds the minimum of 30 mL/hr and is acceptable. Pain level of 2/10 after analgesia indicates effective pain management. O2 saturation of 96% on supplemental oxygen is an acceptable postoperative reading.
