Which statement regarding delivering a recommended dose of GBCA to a pregnant patient is true?

The statement regarding delivering a recommended dose of gadolinium-based contrast agent (GBCA) to a pregnant patient that holds true is that mutagenesis has not been observed in human fetuses. This means that, while there are known risks associated with GBCA use in pregnant patients, particularly related to nephrogenic systemic fibrosis (NSF) and other potential complications, evidence does not suggest that GBCA exposure actually causes genetic mutations in human fetuses.

It's important to point out that the safety of administering gadolinium during pregnancy has been a subject of ongoing research. Although there are concerns about potential adverse outcomes, particularly in relation to NSF and the accumulation of gadolinium in fetal tissue, the specific risk of genetic mutations caused by GBCA has not been substantiated by available data.

Understanding the other choices provides context: the development of NSF in fetuses, while a serious consideration, is linked more to those with renal insufficiency and is not established as a direct outcome of GBCA administration in pregnant patients in general. The possibility of issues in the first trimester reflects concerns about teratogenic effects, which involve structural abnormalities, yet there is insufficient evidence to fully associate GBCA use with these outcomes. Teratogenesis has been a point of caution
