A nurse is preparing to administer immunizations to a 5-year-old child who is up-to-date with the current immunization schedule. Which of the following immunizations should the nurse plan to administer?

The correct answer is B: Varicella. Varicella vaccine is typically given to children around 12-15 months of age, and a second dose is recommended at around 4-6 years. Since the child is 5 years old and up-to-date with the immunization schedule, the nurse should plan to administer the second dose of the varicella vaccine to ensure continued protection against chickenpox. Choice A (Rotavirus) is usually given in infancy, so it is not needed at this age. Choice C (Haemophilus influenzae type b) is typically administered in infancy and early childhood. Choice D (Hepatitis B) is usually given shortly after birth and during early childhood. The other choices are not relevant in this scenario.
