01 An adolescent couple seeks advice to reduce the risks of both pregnancy and sexually transmitted infections (STIs). Which counselling message is scientifically most appropriate?
Answer and explanation
Correct answer: A. Use condoms correctly and consistently; another contraceptive method may be added for extra pregnancy protection when appropriate, because condoms reduce the transmission risk of many STIs.
Explanation: Correct and consistent condom use reduces the risk of pregnancy and lowers transmission risk for many STIs. Another suitable contraceptive method can provide additional pregnancy protection. Oral contraceptive pills do not protect against STIs, and antibiotics do not prevent all STIs or justify self-medication.
