Have you ever tried an imagination exercise? Lay down somewhere dark, quiet and comfortable. Vividly imagine walking into a patients room, picture the bed, the TV, the white board, the sink, the paper towels, the bathroom. Next visualize the bed. Its in the low position, the two top rails are up. Now, visualize the hard part, the patient. Get the patient to look as real as you can. Maintain the other parts of the room also, dont get tunnel vision. Visualize the patient smiling at you, very pleasantly. See yourself walk in, say hello and your name. Ask him/her how their morning has been. Ask them if they slept well. Ask how they are feeling. Tell them you are going to do X procedure, explain the procedure. The whole while, imagine all responses from the patient as positive. Move on to the procedure. All your supplies are there, you have seen the order, you already know how to do the procedure since you have read this before. You begin the procedure all while explaining to the patient what you are doing and why. Remember, the patient is happy you are there and is still smiling (even if it's an IV or something, see them smiling).
Go through this several times at about the same time each day. Take your time with the visualization. Vividly imagine it all! Stay calm in the exercise. While you are relaxed and going through pay attention to your heart rate and how you feel. Keep your heart rate low. Keep your body relaxed.
When you are ready to go into a patients room, close your eyes, take a deep breath and remember that calm feeling. Bring it back and maintain it. You will do fine!
