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 B
Explanation
A. "You should gradually increase lactose products in your diet." For adolescents with lactose intolerance, gradually increasing lactose products may worsen symptoms. The goal is to reduce or avoid lactose-containing foods to prevent discomfort.
B. "You should drink rice milk instead of cow's milk." Rice milk is lactose-free and can be a suitable alternative to cow's milk for someone with lactose intolerance. It is an appropriate recommendation for managing the condition.
C. "You should limit your intake of calcium-fortified orange juice." Calcium-fortified orange juice is a good source of calcium, and it can be consumed without concern for lactose intolerance. It can help provide calcium, especially if dairy intake is limited.
D. "You should eat flavored yogurt instead of plain yogurt." Flavored yogurt may contain added sugar and artificial ingredients, which are not necessarily better than plain yogurt. Plain yogurt can be easier to digest.
Correct Answer is A
Explanation
A. Determine if the toddler has an allergy to iodine prior to the procedure: Cardiac catheterization typically involves the use of iodine-based contrast dye. It is crucial to determine if the toddler has an allergy to prevent any adverse reactions, during the procedure.
B. Check the toddler's vital signs once each hour following the procedure: After a cardiac catheterization, vital signs should be monitored more frequently than once per hour. Typically every 15-30 minutes during the first few hours following the procedure to detect any complications.
C. Give the toddler clear liquids prior to the procedure: Clear liquids are restricted before a procedure like cardiac catheterization, especially if sedation or anesthesia is involved. The child may be required to fast for several hours before the procedure to reduce the risk of aspiration.
D. Administer meperidine for pain immediately following the procedure: Meperidine is not recommended for pain management in children due to its potential for side effects, including seizures. Safer alternatives, like acetaminophen or morphine, are preferred
