A nurse is assisting with the collection of a bone marrow specimen from a preschooler. Which of the following actions should the nurse take?

Choice A rationale:
Hematocrit 36%. A hematocrit level of 36% falls within the normal range for adolescents. Hematocrit measures the proportion of blood volume occupied by red blood cells and is used to assess for anemia or polycythemia. A level of 36% is not a cause for concern in this case.
Choice B rationale:
Hemoglobin 12 g/dL. A hemoglobin level of 12 g/dL is within the normal range for adolescents. Hemoglobin is a protein in red blood cells that carries oxygen. This level indicates that the adolescent is not significantly anemic.
Choice C rationale:
Glucose 120 mg/dL. A glucose level of 120 mg/dL is within the normal range for a random blood glucose test. However, in the context of diabetes mellitus, the nurse should be more concerned about the HbA1c level, which reflects the average blood glucose level over the past few months.
Choice D rationale:
HbA1c 10.7%. HbA1c, or glycated hemoglobin, reflects the average blood glucose concentration over a span of approximately 2 to 3 months. An HbA1c level of 10.7% is significantly elevated and indicates poor long-term glucose control. This value suggests that the adolescent's diabetes management has not been effective, which can lead to an increased risk of diabetes-related complications over time. The nurse should notify the healthcare provider so that appropriate adjustments can be made to the treatment plan.

Choice A rationale:
The Rotavirus vaccine is typically administered to infants, usually starting at 2 months of age, to protect against severe diarrhea and vomiting caused by rotavirus infection. However, the child in question is 11 years old, and the rotavirus vaccine is not recommended for administration at this age. The vaccine's protection window is within the infant and early childhood period, and the child would likely have received this vaccine earlier.
Choice B rationale:
Haemophilus influenzae type b (Hib) Hib vaccine is recommended as a series of doses to protect against Haemophilus influenzae type B infection, which can lead to severe illnesses like meningitis and pneumonia. While the child may have received this vaccine in infancy, a booster dose is often recommended around age 11 to ensure ongoing protection. This choice is correct for the given age group.
Choice C rationale:
Hepatitis A Hepatitis A vaccine is typically administered in two doses, with the first dose given at age 1 and the second dose administered at least 6 months later. The child in question is 11 years old, and assuming the child received the vaccine as per the standard schedule, there would be no need to administer this vaccine again.
Choice D rationale:
Human papillomavirus (HPV) HPV vaccine is recommended for adolescents to protect against several strains of the human papillomavirus that can lead to various cancers later in life. It's usually administered in a series of doses starting around age 11 or 12. However, the prompt states that the child is already up-to-date with current immunizations, and if the child received the HPV vaccine at the appropriate age, there would be no need for another dose at this time.
