A nurse is assessing an adolescent who has type 1 diabetes mellitus. Which of the following findings is the nurse’s priority?
A Cholesterol 189 mg/dL
B HbA1c 11.5%
C Glycosuria
D Preprandial blood glucose 124 mg/dL
The correct answer and Explanation is :
The priority finding among the options provided is B: HbA1c 11.5%.
Explanation:
HbA1c, or hemoglobin A1c, is a critical marker for assessing long-term glucose control in patients with diabetes. It reflects the average blood glucose levels over the past 2-3 months. For adolescents with type 1 diabetes mellitus, the target HbA1c is generally below 7.0% to reduce the risk of long-term complications such as neuropathy, retinopathy, and nephropathy. An HbA1c of 11.5% indicates poor long-term glucose control, which significantly increases the risk of these complications.
Comparative Importance of Other Findings:
- Cholesterol 189 mg/dL: While elevated cholesterol levels are a concern, especially in patients with diabetes who are at increased risk of cardiovascular disease, this is not an immediate concern compared to poor glucose control. Cholesterol levels can be managed through dietary changes and medications, but they do not have the immediate impact on the patient’s health as a high HbA1c.
- Glycosuria: The presence of glucose in the urine (glycosuria) indicates that blood glucose levels are high. While this is important, it is often a consequence of poor glucose control and is less critical to address immediately compared to the long-term effects of an elevated HbA1c.
- Preprandial blood glucose 124 mg/dL: This blood glucose level is within a reasonable range and does not immediately indicate a significant problem. Preprandial (before meal) glucose targets for many adolescents are typically between 90 and 130 mg/dL. Thus, a reading of 124 mg/dL is not alarming and does not warrant immediate intervention.
In summary, the priority for the nurse is to address the elevated HbA1c of 11.5% because it signifies a chronic issue with blood glucose management, which poses a higher risk for serious complications in the long term. Effective strategies to improve HbA1c include optimizing insulin therapy, education on carbohydrate counting, and addressing any barriers to adherence with diabetes management.
