Final answer:
The nurse in a prenatal class described guided imagery, a relaxation technique using sensory peaceful words, suitable for individuals open to suggestion.
Step-by-step explanation:
The nurse described guided imagery as a technique that involves using sensory peaceful words to help individuals focus on pleasant thoughts and achieve a state of relaxation. This is done by sitting comfortably in a quiet environment, closing the eyes, and possibly repeating a calming mantra. The purpose of guided imagery in a prenatal class would be to reduce stress and promote well-being in expectant mothers.
Guided imagery can enhance cognitive processes such as learning and mindfulness, similar to meditation, but differs from practices like singing, massaging, and simply listening to music. This technique is particularly suitable for individuals open to the power of suggestion, like hypnosis, but relies on self-guided mental imagery.
