A nurse is reinforcing teaching with an adolescent client about the purpose of the glycosylated hemoglobin (HbA1c) test. Which of the following descriptions should the nurse include in the teaching?
"It measures the amount of oxygen circulating in the blood."
"It measures the amount of immature white blood cells."
"It measures the glucose circulating in the blood stream.
"It measures the amount of red blood cells."
The Correct Answer is C
A. "It measures the amount of oxygen circulating in the blood." The HbA1c test does not measure oxygen levels. Oxygen levels in the blood are measured through tests like pulse oximetry or arterial blood gas tests.
B. "It measures the amount of immature white blood cells." The HbA1c test measures the average blood glucose levels over the past 2-3 months, not white blood cells. The immature white blood cell count is assessed through a different blood test (e.g., a complete blood count).
C. "It measures the glucose circulating in the blood stream." The HbA1c test reflects the average blood glucose levels over the past 2-3 months by measuring the percentage of hemoglobin that has glucose attached to it.
D. "It measures the amount of red blood cells." The HbA1c test does not measure the number of red blood cells; it measures the percentage of hemoglobin in red blood cells that is bound to glucose, which helps assess blood sugar control over time.

Correct Answer is D
Explanation
A. Maintain the child in a supine position: The child should not be in a supine (lying flat) position during enteral feedings, as this increases the risk of aspiration. The child should be positioned upright or at least 30 to 45 degrees to reduce this risk.
B. Discard gastric residuals prior to each feeding: While it is important to check gastric residuals before each feeding to ensure proper gastric emptying, residuals should not automatically be discarded. Depending on the volume of residuals, the feeding may need to be delayed or adjusted rather than discarded.
C. Warm the feeding in the microwave oven for 15 seconds: Feeding should never be warmed in the microwave because it can cause uneven heating, which could lead to burns. Feedings should be warmed using a safe method, such as a warm water bath, to ensure even temperature.
D. Administer the feeding to the child at 10 mL/min: Administering the feeding at a slow and controlled rate, such as 10 mL/min, is recommended to prevent discomfort and reduce the risk of aspiration. This rate allows the digestive system to process the feeding properly.
Correct Answer is ["A","C","E"]
Explanation
A. Ensure the scale is balanced to "0" before weighing the infant: It is important to calibrate the scale to "0" before weighing the infant to ensure an accurate measurement. This step helps to avoid any errors in weight assessment.
B. Place a stadiometer on the top of the infant's head to measure their length: A stadiometer is typically used for measuring height in older children and adults, but for infants, a length board (not a stadiometer) should be used.
C. Cover the scale with a clean sheet of paper: This is essential for hygiene and to provide a clean, warm surface for the infant, especially when they are undressed for weighing.
D. Obtain the infant's weight with their diaper on: To obtain an accurate weight, the infant should be weighed without the diaper. A diaper adds weight that could affect the accuracy of the measurement.
E. Measure the infant's length from the crown of the head to the heels of the feet: For accurate length measurements in infants, the measurement should be taken from the crown of the head to the heels of the feet while the infant is lying flat on a length board.
