Step-by-step explanation:
The most important instruction for the nurse to provide to the middle-aged woman with type 2 diabetes mellitus (DM) to lower her blood glucose and increase her serum high-density lipoprotein (HDL) levels is to make lifestyle changes, including a healthy diet and regular physical activity.
By adopting healthier behaviors such as choosing foods that are low in carbohydrates and high in fiber, the woman can lower her blood glucose levels. Regular exercise, such as brisk walking or jogging, can also help improve insulin sensitivity and promote weight loss, which can further benefit blood glucose control.
Additionally, the nurse should emphasize the importance of stress management, as stress can increase blood glucose levels. Breathing exercises and replacing stressful thoughts with calming ones can be helpful in managing stress.
