Which vital sign change may indicate a significant concern in a post-surgery client?

Rapid shallow breathing is a vital sign change that may suggest significant concern in a post-surgery client due to various reasons, such as respiratory distress or pain. After surgery, especially thoracic or abdominal, patients may experience complications like pneumonia, atelectasis, or inadequate ventilation. Rapid breathing often indicates the body is attempting to compensate for decreased oxygenation or increased carbon dioxide levels. Shallow breathing, on the other hand, might suggest that the patient is unable to take deep breaths due to pain or discomfort following surgery, which can lead to ineffective ventilation and hypoxemia. Monitoring this change in respiratory rate and depth is crucial; it can serve as an early indicator of complications, enabling timely interventions to ensure the patient's well-being.
