What is a critical consideration for the nursing care of a pregnant client with a history of heart disease?

In nursing care for a pregnant client with a history of heart disease, limiting stress and infection exposure is a critical consideration. This patient population is particularly vulnerable, as stress can exacerbate cardiac conditions and lead to complications for both the mother and fetus. High levels of stress can increase blood pressure and heart rate, potentially leading to adverse events such as heart failure or other cardiovascular complications during pregnancy.

Furthermore, exposure to infections can pose significant risks to a pregnant woman with existing heart disease, as infections can strain the heart and may contribute to worsening of the condition or complications during pregnancy. Therefore, implementing strategies to manage stress, promote relaxation, and minimize exposure to infectious agents is essential in providing safe and effective care to these patients, ensuring both maternal and fetal well-being throughout the pregnancy.
