Final answer:
The nurse should instruct the assistive personnel to administer prescribed antibiotics as scheduled.
Step-by-step explanation:
The nurse should give the assistive personnel the instruction to administer prescribed antibiotics as scheduled. Bacterial meningitis is an infection of the membranes that cover the brain and spinal cord, and it is treated with antibiotics. This is important to help eliminate the bacterial infection and prevent further complications. Other instructions such as administering acetaminophen for fever as needed or providing a diet high in potassium are not directly related to treating bacterial meningitis.
