Final answer:
The nurse is practicing b) Autogenic Training, where specific phrases are used to control the body with the mind to relieve anxiety.
Step-by-step explanation:
In the scenario described, the nurse is likely utilizing a technique known as Autogenic Training (Option B). This technique involves the practice of relaxing the body by focusing on calming thoughts and reciting specific phrases that induce a state of relaxation and reduced anxiety. Autogenic training is a form of self-hypnosis that is often used to reduce stress and help to manage various psychosomatic conditions.
Techniques similar to Autogenic Training are guided imagery and image visualization, where a person is guided by a narrator to envision a peaceful scene or scenario. This should not be confused with meditative techniques, which may involve mantras but are more broadly about achieving a state of mindfulness or concentration. Although these techniques share similarities in their focus on the mind-body connection and stress reduction, Autogenic Training specifically uses self-suggested affirmations to achieve its effects, making it the most accurate choice for the described practice.
