A nurse is collecting data from a client who is 12 hr postoperative following intestinal surgery. Which of the following findings should the nurse report to the charge nurse prior to client ambulation?

An oxygen saturation level of 90% is below the normal range and indicates inadequate oxygenation. This finding could indicate respiratory compromise or impaired lung function, which may require further assessment and intervention before allowing the client to ambulate. The respiratory rate of 20 breaths per minute, apical pulse rate of 88 beats per minute, and oral temperature of 37.6°C (99.7°F) are within the expected range and do not raise immediate concerns that require reporting to the charge nurse prior to ambulation. However, the nurse should continue to monitor these vital signs during and after ambulation to ensure stability.
