The nurse is preparing to admit a patient from the emergency department. The transferring nurse reports that the patient is obese.
 
  The nurse has been overweight at one time and works very hard now to maintain a healthy weight. She immediately thinks to herself, I know I tend to feel negatively about obese people; I figure if I can stop eating, they should be able to. I must remember how very difficult that is, and be very careful not to be judgmental of this patient. This best illustrates:
  1) Theoretical knowledge.
  2) Self-knowledge.
  3) Using reliable resources.
  4) Use of the nursing process.
