Which of the following is a key consideration for a nurse caring for a pregnant client with asthma?

Maintaining adequate airflow is essential for a pregnant client with asthma because it directly impacts both maternal and fetal health. Asthma can lead to episodes of bronchoconstriction, which can impair oxygen delivery to both the mother and the fetus. Ensuring that the mother's airways remain open and functioning effectively is crucial for preventing hypoxia, which can have adverse effects on fetal development and well-being.

Effective asthma management, which includes medication adherence and monitoring of symptoms, helps maintain adequate airflow and reduces the risk of asthma exacerbations. This proactive approach helps ensure that the mother can breathe freely and maintain optimal oxygen levels, thus safeguarding the health of both her and her unborn child.

While other considerations, such as avoiding allergens and monitoring fetal heart rate, are important, they do not directly address the immediate need for maintaining lung function and oxygenation, which is the primary concern in managing asthma during pregnancy.
