A nurse is assisting with the care of an adolescent. Which of the following statements should the nurse identify as high-risk behaviors?

A) I participate in physical activities 3 times per week: Engaging in physical activity is a positive behavior and is not considered high-risk. Regular physical activity is important for maintaining overall health and preventing obesity, cardiovascular disease, and other health issues. B) I use sunscreen with an SPF of 10: While using sunscreen is a protective behavior, an SPF of 10 is lower than the recommended SPF of at least 30 for effective protection against harmful UV radiation. This is not the most significant high-risk behavior compared to others, but it still indicates some risk of sun damage. C) I limit playing video games to 3 hours per day: Limiting screen time to 3 hours per day can be considered a balanced approach to video gaming. While excessive screen time can be problematic, 3 hours per day is not necessarily a high-risk behavior for an adolescent, as long as it doesn't interfere with other important aspects of life, like physical activity, sleep, and socialization. D) I have had sexual relations, but did not get the HPV vaccine: Engaging in sexual activity without receiving the HPV vaccine is a high-risk behavior. The HPV vaccine helps prevent certain strains of the human papillomavirus, which can cause cervical cancer and other cancers. Lack of vaccination increases the risk of contracting HPV and developing related complications.
