A parent asks the nurse how to care for their 4-year-old child after receiving the Haemophilus influenzae type b (Hib) conjugate vaccine. Which instruction should the nurse provide?

Choice A reason: Children's aspirin is not recommended due to the risk of Reye's syndrome and is not typically used for post-vaccination care. Choice B reason: While fever can occur after vaccination, not all fevers are serious and can often be managed at home unless they are high or persistent. Choice C reason: Keeping the child home from daycare is not necessary unless the child is feeling unwell or has a fever. Choice D reason: Applying a cool pack to the injection site is a common recommendation to reduce discomfort and swelling after vaccinations.
