Which assessment finding would indicate worsening status in a woman with cardiovascular disease during labor?

In the context of a woman with cardiovascular disease during labor, increased shortness of breath signifies a potential worsening status. This is particularly important to recognize, as shortness of breath can indicate a decline in the heart's efficiency to handle the increased demands placed on it during labor. In women with cardiovascular conditions, the body is already under stress, and any additional strain can exacerbate existing issues such as heart failure or pulmonary edema.

While increased urine output might suggest adequate renal perfusion and could be a sign of good cardiac output, it does not indicate deterioration. A decreased heart rate could also suggest an adequate response to stress or even a potential vagal response, which is not necessarily a sign of worsening condition when considered alone. Lastly, stable blood pressure indicates that the woman's cardiovascular status may be maintained; however, reliance on blood pressure alone is insufficient in a dynamic situation like labor. Therefore, increased shortness of breath is a highlighted warning sign that demands immediate attention and assessment.
