I may have to agree with kheemoy because we just have to answer what is being asked. For that question, "Which of the following independent nursing actions should the nurse implement to limit spread of Mr. Del Ray's ankle edema?", Let me just justify the cues that we have. First, We have the word Independent nursing action (nurse initiative) which means autonomous actions of the nurse, and based on the nursing diagnoses and client-centered goals that we us a nurse acts on our own intiative, without instructions from other persons/disciplines(physicians). Second, How do we intervene if a patient has a ankle edema? Based on what i know, one of the intervention for ankle edema (swollen legs or ankle) is to Raise your legs above your heart while lying down. Although #1 restricting his fluid is a good answer. We need an order from the doctor before we can implement that. So it will not be a independent nursing action. It will be Interdependent intervention. So I therefore conclude that my answer to that question is #4 Elevating his legs Cheer guys,,
