Which statement from a client would raise concern about the risk of sexually transmitted infections?

The statement indicating uncertainty about the identity of the father of the baby raises significant concern regarding the risk of sexually transmitted infections (STIs). This uncertainty suggests potential involvement with multiple partners, which inherently increases the likelihood of exposure to STIs. Engaging with multiple partners can complicate the situation as it may lead to unmonitored sexual history, making it difficult to ascertain if any partner carries STIs.

In contrast, the other statements reflect behaviors or circumstances that suggest lower risk scenarios. For instance, asserting that a partner is monogamous suggests a stable relationship with reduced potential for exposure to infections. Indicating recent testing demonstrates proactive health management, contributing to an understanding of the individual's sexual health. Consistently using protection indicates responsible sexual behavior, further lowering the risk of STIs.
