A Patient with Extensive Second-Degree Burns on His Legs and Trunk

A patient with extensive second-degree burns on his legs and trunk is using patient-controlled analgesia (PCA) with IV morphine to be delivered at 1 mg every 10 minutes to control his pain.Several times during the night,he awakens in severe pain,and it takes more than an hour to regain pain relief.What is the most appropriate nursing action at this time?

A) Administer a dose of morphine every hour from the PCA machine while the patient sleeps.
B) Request that the physician order a bolus dose of morphine to be given when the patient awakens with pain.
C) Consult with the patient's physician about adding a continuous morphine infusion to the PCA regimen at night.
D) Teach the patient to push the button every 10 minutes for an hour before he goes to sleep,even if he has minimal pain at that time.
