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. A blood pressure of 95/58 mm Hg can be within an acceptable range for an infant and is not typically a cause for concern in a 2-month-old.
B. A respiratory rate of 18/min is abnormally low for a 2-month-old infant. Infants normally have a respiratory rate of about 30–60/min, and a low rate may indicate respiratory depression or other serious issues that should be reported promptly.
C. A temperature of 37.4° C (99.3°F) is within the expected range for an infant and does not indicate fever.
D. A heart rate of 160/min is within the normal range for a young infant, especially when awake or active.
Correct Answer is {"dropdown-group-1":"C","dropdown-group-2":"C"}
Explanation
Rationale for Correct Choices:
- Consult the child life specialist for guidance: A child life specialist can help the parent navigate the difficult conversation with their adolescent, providing strategies for addressing sensitive topics like metastasis and death.
- Reinforce teaching to the parent regarding the adolescent's potential emotional responses: Educating the parent on common emotional responses helps them prepare for and better support their adolescent through this challenging time.
Rationale for Incorrect Choices:
- Encourage the parent to hide their emotions from their adolescent: Hiding emotions can create barriers to trust and communication, which can make the adolescent feel isolated or confused.
- Instruct the parent to withhold the test results from their adolescent: Withholding important information can prevent the adolescent from understanding their condition and making informed decisions about their care.
- Discourage the parent from discussing the possibility of death with their adolescent: Avoiding discussions about death can prevent the adolescent from processing their emotions and understanding the reality of their situation.
- Collaborate with the RN to initiate a referral for admission to hospice care: Hospice care should only be considered after emotional support and clear communication have been established, not prematurely without addressing emotional needs first.
