Step-by-step explanation:
The technique that the patient is using to alleviate pain by thinking about vacationing on the beach is known as imagery. This nonpharmacologic approach involves using one's imagination to visualize a pleasant and relaxing setting, which can help distract the mind from pain. Distraction indeed plays a role in this method, but imagery is more specifically related to the mental visualization of peaceful scenes or experiences, a technique commonly used in pain management and stress reduction.
