Hi. I'm studying for the NCLEX and having trouble understanding a review question and the answer to the question. The question is a select all that apply question and the scenario involves discharge teaching for a patient with "peripheral vascular disease." One of the correct answers is to "keep extremities elevated on pillows" because it promotes venous return. My confusion is that I thought the term "peripheral vascular disease" included both peripheral arterial disease and chronic venous insufficiency. I thought that peripheral vascular disease either meant both or was usually taken to mean PAD moreso than CVI. If the patient has PAD, then elevating the extremities would impede arterial circulation in the extremities. So, if the question asks about PVD, how do I know if they are referring to PAD or CVI? Thanks for any help!
