Which data most directly indicates a postoperative patient can safely ambulate?

• A. Heart rate
• B. Temperature
• C. Respiratory status and oxygen saturation
• D. Blood glucose

Answer: (C)

The key factor is whether the patient’s lungs and oxygen delivery are capable of meeting the increased demand of movement. Respiratory status and oxygen saturation directly show how well oxygen is being taken in and transported to tissues during activity. If breathing is stable and the oxygen saturation is within the patient’s normal or target range, ambulating is generally safe because the body can meet the extra oxygen needs that come with walking. In contrast, others data can be influenced by factors that don’t reflect readiness for movement: heart rate can rise from pain or meds and doesn’t by itself prove adequate oxygen delivery; fever points to infection but doesn’t tell you about immediate tolerance to ambulation; blood glucose matters for energy and healing but doesn’t directly indicate safe ambulation. So the data that most directly indicates readiness to ambulate is respiratory status and oxygen saturation.
