Which of the following are critical steps a nurse should take when setting up a PCA pump for a postoperative patient? (Select all that apply.)

Choice A reason: Reviewing the PCA settings with the patient helps ensure they understand how to use the device safely and effectively. It also reinforces patient autonomy and informed consent, which are essential in pain management. Choice B reason: Verifying the medication and dosage with another nurse is a standard safety protocol to prevent medication errors. PCA pumps involve controlled substances and require double-checking to ensure correct programming and dosing. Choice C reason: Ensuring the PCA pump is connected to a proper electrical outlet prevents power failure and device malfunction. PCA pumps must remain continuously powered to deliver analgesia as programmed. Choice D reason: Checking the IV site for patency and proper connection ensures that the medication is being delivered effectively and reduces the risk of infiltration or extravasation. A compromised IV site can lead to inadequate pain control and tissue damage.
