A nurse is reinforcing teaching about food choices with a parent of a child who has celiac disease. Which of the following responses by the parent indicates an understanding of the teaching?

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.

Choice A rationale:
Positioning the child sitting with their buttocks at the edge of the table is not appropriate for collecting a bone marrow specimen from a preschooler. This position does not provide adequate access to the bone marrow aspiration site and may lead to discomfort for the child.
Choice B rationale:
Placing the child in a prone position (lying face down) is suitable for collecting a bone marrow specimen from a preschooler. This position exposes the posterior iliac crest, which is a common site for bone marrow aspiration. It allows for easier access to the bone marrow and reduces the risk of injury.
Choice C rationale:
Positioning the child side-lying to expose the vertebrae is not the recommended position for bone marrow aspiration. The iliac crest, not the vertebrae, is the usual site for this procedure in children. Placing the child in a side-lying position would make it difficult to access the appropriate site.
Choice D rationale:
Placing the child supine with legs flexed outward into a frog-like position is suitable for collecting a bone marrow specimen. This position provides access to the iliac crest while allowing for better immobilization of the child. It also ensures the child's safety and comfort during the procedure.
