Final answer:
In teaching a client with a PCA pump in the immediate post-op period, the nurse should emphasize that a dose of medication is administered every time the button is pushed.
Step-by-step explanation:
The nurse should include the following statement in the teaching: 'You will receive a dose of medication every time you push the button.' This is an important point to emphasize because it ensures that the client understands how the PCA pump works. It is essential to educate the client that pushing the button triggers the administration of a preset dose of medication, which helps in managing their pain effectively.
Statements b, c, and d are incorrect. It is important to encourage the client's active participation in managing their pain and not discourage it by restricting family involvement. However, it is crucial to instruct the client to not allow others to push the button on their behalf. Secondly, it is essential to educate the client that there is a preset limit or ceiling to prevent overdosing, thus statement c is incorrect. Finally, it is not advisable to wait until pain reaches a severe level before requesting pain medication, as it is more effective to manage pain before it becomes too intense.
