A nurse is caring for a patient who is scheduled for surgery. This nurse is providing preoperative teaching to this patient about pain management using a patient-controlled analgesia (PCA) system. Which of the following statements should the nurse include?

Push the button on the PCA prior to your pain level becoming severe so you can remain comfortable.

There is minimal risk of an overdose of pain medication while using a PCA pump.

Your family member should push the PCA button for you while you are sleeping.

You will still have to request pain medication from the nurse from time to time.

Using the PCA regularly will provide a consistent level of pain relief.
