Final answer:
When changing a gown for someone with an IV, the IV bag must remain above the arm to maintain proper flow, and a healthcare professional should check the flow rate afterwards.
Step-by-step explanation:
When changing the gown on a person with an IV, it is important not to disrupt the flow of the intravenous fluid or the positioning of the IV bag relative to the patient's arm. The correct procedure would be to keep the IV bag above the person's arm. This avoids any interruption in the flow rate caused by gravity. Stopping the IV pump or disconnecting the IV is not generally needed and could introduce complications or require additional steps to resume the infusion safely. Therefore, the answer to the question is to keep the bag above the arm, and after changing the gown, have the nurse or a healthcare professional check the flow rate to ensure it has not been altered in the process.
