Which comment by an adolescent indicates a need for further education about pregnancy prevention?

The statement indicating a need for further education about pregnancy prevention is the one suggesting that pregnancy cannot occur if sex happens during a period. This reflects a misunderstanding of how ovulation and fertility work. Although the chances of conception may be lower during menstruation due to the timing of ovulation in a typical cycle, it is still possible for sperm to survive for several days in a woman’s reproductive tract. If ovulation occurs shortly after menstruation, there is a risk of pregnancy.

In contrast, the other statements show a better understanding of pregnancy prevention and sexually transmitted infections (STIs). The claim that the pill prevents STIs is a misconception, but it reflects an awareness of contraceptive methods, albeit incorrectly. The mention of a condom helping to prevent pregnancy showcases a basic knowledge of barrier methods and their effectiveness in reducing both pregnancy and STI transmission. Recognizing that STIs can still occur when using condoms highlights an understanding of the importance of using protective measures, even when they are in use.
