A nurse is preparing a 12-month-old for routine well-child immunizations per the CDC ACIP schedule. Which actions and statements reflect correct evidence-based practice? Select all that apply.

Option 1 is correct because routine vaccination at 12-15 months includes the first MMR, varicella, and hepatitis A doses and the indicated PCV dose. Option 2 is correct because the nurse verifies the child with two identifiers, follows medication-administration rights, and obtains the required consent. Option 3 is correct because live vaccines such as MMR and varicella are contraindicated with severe immunocompromise or immunosuppressive high-dose systemic corticosteroid therapy. Option 4 is correct because the appropriate Vaccine Information Statement must be given before vaccination. Option 5 is incorrect as written: current product guidance may permit intramuscular or subcutaneous administration for varicella-containing products, but intramuscular administration does not provide faster seroconversion; the nurse must follow the route specified for the product and current guidance.
