A. The patient should be the only one to control the PCA pump. This is to prevent overmedication and to ensure the patient is in control of their pain management.
B. While it's important to use the PCA responsibly, the device is designed to prevent overdose. It has built-in safeguards to limit the amount of medication delivered.
C. This statement indicates that the patient understands the importance of communicating with the nurse about pain management. If the PCA is not effectively controlling pain, the nurse needs to be notified to adjust the medication or explore other options.
