A nurse is reinforcing teaching about the purpose of the HbA1c test with an adolescent who has type 1 diabetes mellitus. Which of the following statements by the adolescent indicates an understanding of the teaching?
"This test checks for ketones in my urine."
"This test measures the amount of hemoglobin in my blood."
"This test tells me how much oxygen my body is carrying."
"This test checks my blood sugar over the last few months.”
The Correct Answer is D
A. The HbA1c test does not check for ketones in urine. Ketone testing is separate and used to assess for diabetic ketoacidosis or inadequate insulin use, not for monitoring long-term blood glucose control.
B. While the HbA1c test involves hemoglobin, it does not measure the total amount of hemoglobin in the blood. Instead, it reflects the percentage of hemoglobin that has glucose attached to it over a period of time.
C. The HbA1c test does not measure oxygen levels in the blood. It specifically measures the average blood glucose level over a 2-3 month period by assessing the percentage of glucose-bound hemoglobin.
D. The HbA1c test provides an indication of long-term blood glucose control, reflecting the average blood glucose levels over the past 2-3 months. It is a crucial tool for managing diabetes and monitoring the effectiveness of treatment plans.

Explanation
A. Lansoprazole is a proton pump inhibitor (PPI) that is most effective when taken 30 minutes before meals, as it works by reducing stomach acid production in response to food intake.
B. Lansoprazole capsules should not be placed under the tongue, as they are intended to be swallowed whole to ensure proper absorption.
