Use this scenario to answer questions #39-42: You are caring for a 12-year-old girl with acute lymphoblastic leukemia. She is responsive, but she does not feel well and appears to be flushed. Her temperature is 39°C (102.2°F), heart rate is 118/min, respiratory rate is 36/min, blood pressure is 100/40 mm Hg, and oxygen saturation is 96% on room air. Your assessment reveals mild increase in work of breathing and bounding pulses. The child is receiving 100% oxygen by nonrebreathing mask. What assessment finding is most important in your determination of the severity of the patient’s condition?
