In a woman with heart disease in the second stage of labor, which assessment findings are of greatest concern?

• A. Edema, basilar rales, and an irregular pulse.
• B. Increased urinary output and tachycardia.
• C. Shortness of breath, bradycardia, and hypertension.
• D. Regular heart rate and hypertension.

Answer: (A)

The main concept here is recognizing signs of cardiac decompensation during labor in a woman with heart disease. Edema and basilar rales point to fluid overload and possible pulmonary edema, which reflects the heart’s inability to handle the increased circulatory demands of labor. An irregular pulse adds concern by suggesting an unstable rhythm or conduction problem, further indicating hemodynamic instability that needs prompt attention.

In this scenario, edema shows fluid accumulating in tissues, and basilar crackles indicate fluid in the lungs. Together, they signal congestive heart failure in the setting of pregnancy, especially during the strenuous second stage when venous return and cardiac workload rise. An irregular pulse reinforces that the heart’s rhythm or rate is not well controlled, increasing the risk of deterioration for both mother and fetus.

The other options don’t combine signs as strongly. Increased urinary output and tachycardia can occur with normal labor and sympathetic activation and don't necessarily indicate fluid overload. Shortness of breath with bradycardia and hypertension could raise concern, but the bradycardia is a less typical sign of acute heart failure in this context and hypertension alone is not as telltale without edema or lung signs. Regular heart rate with hypertension suggests stability, not the urgent decompensation indicated by the edema, rales, and irregular pulse.

So, the presence of edema, basilar rales, and an irregular pulse best signals the need for immediate evaluation and potential escalation of care.
