A nurse is caring for a client who is postoperative and using a PCA pump. For which of the following actions should the nurse intervene?

A. Administering a PCA dose prior to dressing changes is appropriate for managing pain before potentially painful activities. B. Ambulating with the PCA pump is acceptable, as long as the client is not disconnected and it does not interfere with the pump's function. C. Requesting a partner to administer PCA doses is incorrect because only the patient should administer PCA doses to prevent overmedication and to ensure that the client is aware of their pain level. D. Administering PCA doses as soon as pain returns is appropriate as long as the client follows the prescribed timing for PCA use.
