What should a nurse assess regarding a patient’s relationship with her husband during pregnancy?

Assessing a patient's relationship with her husband during pregnancy is crucial for understanding the overall health and stability of her environment. Focusing on whether there is any exposure to substance use is particularly important because substance use can significantly affect both the mother's health and the developing fetus. Substance use during pregnancy can lead to various complications, including preterm labor, low birth weight, and developmental issues for the child. Moreover, a partner’s substance use may impact the emotional and physical support the mother receives, which is essential for her well-being during pregnancy.

While the other options also touch on important facets of a relationship, they do not address the immediate concerns that substance exposure presents. Financial support, family dynamics, and future family planning are relevant but may not directly relate to the immediate risks posed by substance use. Therefore, highlighting the assessment of substance exposure provides a more focused lens through which to evaluate the health influences within the relationship during this critical period.
