Final answer:
The nurse should remove excess clothing and blankets from the child, plan to give salicylate in 4 hours if needed, and encourage the child to drink plenty of fluids.
Step-by-step explanation:
When a nurse administers ibuprofen to a child with a high temperature, there are several appropriate actions to take. One action would be to remove excess clothing and blankets from the child in order to help cool their body. Another action would be to plan to give salicylate (aspirin) in 4 hours if needed, as ibuprofen and salicylate can be used together. Lastly, it is important to encourage the child to drink plenty of fluids to prevent dehydration caused by the fever.
