A Children as young as 5 years old have effectively used PCA therapy. Further data
are needed to evaluate the use of PCA therapy in children younger than 5 years
of age.
B Two RNs are needed to check the amount of opioid being administered. Once
the opioid infusion is hung and programmed, a second RN must double-check
the process.
C Children receiving PCA therapy should be monitored closely to ensure effective
pain control and for signs or symptoms of overmedication. Initially, vital signs
should be monitored every 15 to 30 minutes and then every 2 to 4 hours.
Respiratory rate should be assessed every hour.
D Narcan should be readily available to reverse opioid overmedication exhibited by
respiratory distress.
