Pediatric ATI Practice Exam

Which laboratory test indicates the average blood glucose level over the past 2 months for a child with type 1 diabetes?

1. Postprandial blood glucose

2. Fasting blood glucose

3. Glycosylated hemoglobin

4. Mean corpuscular hemoglobin

The correct answer is: Glycosylated hemoglobin

The laboratory test that indicates the average blood glucose level over the past 2 months for a child with type 1 diabetes is glycosylated hemoglobin, commonly known as HbA1c. This test measures the percentage of hemoglobin that is coated with glucose, providing a long-term view of blood sugar control over time. For children with type 1 diabetes, maintaining tight glycemic control is crucial to reducing the risk of complications. The HbA1c test allows healthcare providers to assess how well blood sugar levels have been managed, guiding treatment adjustments as needed. The other tests mentioned do not provide a long-term average of blood glucose levels. Postprandial blood glucose measures the blood sugar level after a meal, which does not reflect overall control. Fasting blood glucose assesses blood sugar after an overnight fast and therefore only gives a snapshot rather than a comprehensive view. Mean corpuscular hemoglobin relates to the amount of hemoglobin in red blood cells and is not relevant to glucose monitoring.
