The nurse is monitoring laboratory results for a client's fasting plasma glucose level. Which fasting plasma glucose range would indicate to the nurse that the client has diabetes? 40 to \( 60 \mathrm{mg} / \mathrm{dL} \) 80 to \( 99 \mathrm{mg} / \mathrm{dL} \) 100 to \( 125 \mathrm{mg} / \mathrm{dL} \) 126 to \( 140 \mathrm{mg} / \mathrm{dL} \)

A fasting plasma glucose level of 126 mg/dL or higher is a clear indicator of diabetes. This value has been established by health organizations as the threshold for diagnosing diabetes. It's important to remember that this test should be done after not eating for at least 8 hours to ensure accurate results. Monitoring fasting plasma glucose is crucial for early intervention. If a client’s glucose levels are consistently elevated, it can lead to serious complications like heart disease, kidney damage, and neuropathy. Engaging in lifestyle changes, such as diet modifications and regular exercise, can be effective in managing or preventing diabetes.
