Carmen Sanchez is a 36-year-old Hispanic woman. She has

come to the clinic today for a follow-up visit after being diagnosed 1 month ago with diabetes. At her last visit, she was provided with education on diabetes. While you as the nurse is preparing to take the client's vital signs, the client states "My husband just lost his job and I do not know what we are going to do. His blood pressure has been up also, but he doesn't want to go to the doctor." The Sanchez family have three children ages 3, 5, and 8. She does not work outside the home. The children are involved in after-school baseball and soccer, and, since they only have one car, the client has to walk the children to their practices when she is not able to carpool. She admits to not being able to follow the diet recommended by the nutritionist because it is difficult to cook different meals for her family and herself. You notices a bottle of soda and a bag of potato chips in the client's bag. At this visit, her fasting blood glucose is 152 mg/dL.
