A nurse is teaching a group of parents about childhood immunizations. The nurse should identify that infants should receive the first dose of which of the following immunizations at 12 months of age?

A. Toddlers with phenylketonuria (PKU) need to limit their intake of phenylalanine, an amino acid found in protein. Therefore, the toddler's protein consumption should be carefully controlled and monitored.

B. Foods high in iron do not need to be specifically limited for a child with PKU. Iron-rich foods are important for overall health and should be included in the diet.

C. Aspartame contains phenylalanine and should be avoided by individuals with PKU. PKU is a metabolic disorder that impairs the body's ability to break down phenylalanine, so it is important to limit phenylalanine intake.

D. This is correct. Foods containing milk products should be avoided, as they are a source of phenylalanine and can contribute to an excessive intake of this amino acid in a child with PKU. Instead, specialized medical foods low in phenylalanine are recommended.

A. There is no need to seal soft toys in a plastic bag for 14 days as impetigo is not typically spread through inanimate objects. However, it is important to discourage the child from scratching the lesions to prevent further spread.

B. Soaking hairbrushes in boiling water is not necessary for the management of impetigo.
Impetigo is caused by bacteria, not lice, so boiling hairbrushes is not a standard recommendation for this condition.

C. This is the correct instruction. Applying a bactericidal ointment (e.g., mupirocin) to the impetigo lesions is a common treatment approach. This helps to eliminate the bacteria causing the infection and promote healing.

D. Administering acyclovir is not indicated for impetigo. Acyclovir is an antiviral
medication used to treat viral infections, such as herpes simplex virus. Impetigo is caused by bacterial infection, not a virus.
