Rationale: Offering cooking classes that focus on healthy recipes is the most effective strategy among the choices provided. These classes not only provide valuable knowledge about nutrition but also offer hands-on experience in preparing healthy meals. This practical approach can significantly impact participants' behavior and increase the likelihood of them adopting healthier eating habits. Distributing educational pamphlets may not have the same level of engagement and interaction as cooking classes. A social media campaign, while informative, may not result in direct behavioral changes. Providing free health screenings, though beneficial for early detection, does not directly address the promotion of healthy eating habits, unlike the hands-on approach of cooking classes.

Continuing heparin therapy without action could lead to severe bleeding complications. Decreasing or increasing the heparin infusion rate would exacerbate the risk of bleeding, making options A, B, and C incorrect.
