Answer 1 is correct because intermittent ice causes vasoconstriction and reduces swelling. Answer 2 is incorrect because heat would cause vasodilation and make swelling worse. Answer 3 is incorrect because an injured joint needs to rest. Range of motion would be painful and disruptive to initial healing. Answer 4 is incorrect because positioning the foot lower than the heart would increase swelling.
