Final answer:
People taking Coumadin should keep their vitamin K consumption consistent and avoid excess intake for blood-clotting and medication efficacy.
Step-by-step explanation:
Anthony's doctor would tell him that he should keep his consumption of vitamin K fairly constant from day to day. This is because Coumadin, the medication he takes, works by blocking the effects of vitamin K, which is essential for blood clotting. If Anthony's vitamin K levels fluctuate too much, it can interfere with the effectiveness of the medication.
Excess vitamin K may increase his risk of hemorrhage in the case of injury. Coumadin is used to thin the blood and reduce the risk of clotting, so consuming too much vitamin K can counteract its effects.
Therefore, it is important for Anthony to maintain a consistent intake of vitamin K and avoid drastic changes in his diet that could affect his medication's efficacy.
