In monitoring peripheral edema for a patient with cor pulmonale, which intervention is most important?

Monitoring peripheral edema in a patient with cor pulmonale is crucial for assessing fluid overload and the effectiveness of treatment. Recording calf circumference daily is significant because it provides a direct measurement of the extent of edema. This approach allows for consistent tracking of changes in fluid retention, which can be indicative of the patient’s condition and response to interventions.

Measuring calf circumference is also a reliable method for identifying any progression of edema, which is particularly important in patients with heart and lung issues where fluid management is essential. By using this method, nurses can determine if the treatment plan is effective or if adjustments are necessary to address the patient's fluid balance.

The other interventions, while potentially important, do not provide as direct or timely feedback on the status of peripheral edema. For instance, assessing skin tenting gives a more generalized idea of hydration status rather than focused insights on peripheral edema. Weighing the patient daily can indicate overall fluid changes, but may not capture localized edema effectively. Obtaining a baseline BNP level helps assess heart failure but does not directly monitor the presence or change in peripheral edema. Therefore, consistently recording calf circumference is the most pertinent intervention for monitoring this specific symptom in patients with cor pulmonale.
