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 my blood sugar over the last few months.
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.
The Correct Answer is A
Choice A rationale
The HbA1c test measures the average blood glucose levels over the past two to three months by assessing the percentage of glycosylated hemoglobin. Hemoglobin within red blood cells binds to glucose, and the higher the blood glucose levels, the more glucose is bound to hemoglobin.
Choice B rationale
The HbA1c test does not check for ketones in the urine. Ketone testing is typically done using urine test strips, which indicate if the body is using fat for energy instead of carbohydrates, a condition that can occur in poorly managed diabetes.
Choice C rationale
The HbA1c test does not measure the amount of hemoglobin in the blood. It specifically evaluates how much glucose is attached to hemoglobin, providing insight into the effectiveness of diabetes management over a period of time.
Choice D rationale
The HbA1c test does not indicate oxygen-carrying capacity. Oxygen levels are assessed by different tests, such as arterial blood gas analysis or pulse oximetry, and are not related to the HbA1c measurement.

Correct Answer is C
Explanation
Choice A rationale
Avoiding participation in school sports is not recommended for children with asthma. Regular physical activity is important for overall health, and with proper management, children with asthma can safely engage in sports. Exercise-induced asthma can be controlled with pre-exercise medication and an asthma action plan, allowing children to remain active without exacerbating their condition.
Choice B rationale
The correct technique for using a peak flow meter involves inhaling deeply and then exhaling quickly and forcefully, not inhaling deeply and quickly. This instruction is incorrect and could lead to improper use of the device, affecting the accuracy of peak flow measurements. Accurate use of the peak flow meter is essential for monitoring asthma control.
Choice C rationale
Pneumococcal immunization is recommended for children with asthma because they are at an increased risk of respiratory infections, which can trigger asthma exacerbations. The vaccine helps protect against pneumococcal bacteria, reducing the likelihood of serious respiratory complications and supporting overall asthma management.
Choice D rationale
Salmeterol is a long-acting beta-agonist used for the maintenance treatment of asthma. It is not intended for managing acute exacerbations. For acute asthma attacks, short-acting bronchodilators such as albuterol are recommended to provide quick relief of symptoms. Using salmeterol for acute exacerbations could result in inadequate asthma control.
