Which of the following is NOT a maternal risk associated with low-dose aspirin use?

The choice regarding congenital anomalies as not being a maternal risk associated with low-dose aspirin use is correct because low-dose aspirin is generally considered safe during pregnancy when used appropriately. Research has consistently shown that taking low-dose aspirin to prevent complications such as preeclampsia does not increase the risk of congenital anomalies in the developing fetus.

In contrast, the other options provided are indeed maternal risks associated with low-dose aspirin use. Active peptic ulcer disease and severe hepatic dysfunction can be exacerbated by the effects of aspirin, as it can irritate the gastrointestinal lining and affect liver function. Gastrointestinal bleeding is a known complication of aspirin, particularly in those with pre-existing gastrointestinal issues, making it an important consideration in managing a pregnant patient. Thus, while low-dose aspirin can be beneficial in reducing certain pregnancy-related risks, it is crucial to be aware of its potential complications and contraindications.
