Final answer:
COPD patients can still be candidates for PCA pumps with careful monitoring and dosage adjustments to prevent respiratory depression.
Step-by-step explanation:
The statement that clients with COPD are not good candidates for PCA (Patient-Controlled Analgesia) pumps is false. While it is essential to exercise caution when prescribing opioids for pain management in COPD patients due to the risk of respiratory depression, PCA can still be utilized under careful monitoring. PCA pumps allow patients to manage their own pain by administering a controlled amount of pain medication, and with proper adjustments to the dosage and monitoring of respiratory function, COPD patients can safely benefit from PCA.
