A Patient with Burns Has the Nursing Diagnosis of Pain

A patient with burns has the nursing diagnosis of pain related to lack of knowledge of pain-control methods. The most appropriate nursing action for this nursing diagnosis is to

A) request that the health care provider order a patient-controlled analgesia machine for the patient.
B) administer pain medications on a routine basis so that pain does not become out of control.
C) teach the patient how to use ordered analgesics with adjunctive methods such as guided imagery and relaxation.
D) use sedative or amnesic drugs in combination with opioids to reduce the perception of the pain experience.
