Which of the following findings would be a priority for follow-up in a client with COPD?

In a client with chronic obstructive pulmonary disease (COPD), maintaining adequate oxygen levels in the body is crucial for their overall health and well-being. Low oxygen saturation indicates that the body's tissues and organs may not be receiving enough oxygen, which can lead to serious complications, including respiratory distress or failure. Therefore, this finding necessitates immediate attention and follow-up to ensure that the client receives appropriate interventions, such as supplemental oxygen or changes in their treatment plan.

In contrast, a decreased heart rate, normal blood pressure, and increased appetite may not present urgent concerns in the context of COPD management. A decreased heart rate may reflect adequate cardiovascular function in some cases, while normal blood pressure could suggest stable hemodynamics. An increased appetite, while generally a positive sign, is less critical than the immediate need to address low oxygen saturation in a respiratory condition like COPD. Therefore, recognizing low oxygen levels as a priority finding helps to prevent further deterioration of the client's condition.
