A 78-year-old patient without polyuria, polydipsia, or polyphagia has a serum glucose level of 130 mg/dL. What should the nurse conclude about this patient?
1. The patient might have eaten a meal with high sugar content prior to the testing.
2. The laboratory results might be erroneous.
3. The patient has type 1 diabetes mellitus.
4. The patient will need to be assessed for other manifestations of diabetes.
Correct Answer: 4
Older adults with diabetes might not present with the classic symptoms of polyuria, polyphagia, or polydipsia. Symptoms of diabetes in older patients can include hypotension, periodontal disease, infections, and strokes. A slight elevation in serum glucose level warrants further investigation. In an adequately functioning endocrine system, dietary intake is managed by the needed amounts of insulin produced by the pancreas. There is no reason to question the laboratory results at this time. There is inadequate information to make a diagnosis of type 1 diabetes mellitus.
