Step-by-step explanation:
The nurse should include increased risk of blood clots as an adverse effect of combined oral contraceptives.
According to the provided information, combined oral contraceptives are associated with a slightly increased risk of blood clots. Although the failure rate of birth control pills is low, there is still a potential risk of developing blood clots. It is important for the nurse to educate the client about this adverse effect and advise them to seek medical attention if they experience symptoms such as leg pain or swelling, chest pain, or shortness of breath.
