Final answer:
The nurse should stop the continuous IV infusion during the IV bolus administration to ensure the proper delivery of the antibiotic medication.
Step-by-step explanation:
When caring for a client who is receiving a continuous IV infusion, the nurse should stop the infusion during the IV bolus administration. This is done to ensure that the antibiotic medication is not diluted or interrupted by the continuous infusion. By stopping the infusion, the nurse can administer the IV bolus separately, allowing the medication to be delivered directly and at the prescribed rate.
