Final answer:
The nurse should document the intervention as 'Therapeutic touch was performed; patient verbalized lessening of pain after treatment'.
Step-by-step explanation:
The nurse should document the intervention as 3) Therapeutic touch was performed; patient verbalized lessening of pain after treatment. This accurately reflects that the nurse used his hands to direct energy fields surrounding the patient's body, and the patient reported a reduction in pain after the intervention. Option 1) refers to tactile distraction, which is not applicable in this situation. Option 2) mentions guided imagery, which is also not mentioned in the question. Option 4) mentions sequential muscle relaxation, which is not described in the question.
