The client asks the nurse, I've heard the student nurses talk about the nursing process. Why is there so much emphasis on using the nursing process? The response that explains the need for nurses to understand and use the nursing process is:
 
  1. Do you think you have a better method we might use?
  2. The nursing process is a systematic problem-solving method encompassing all components necessary to care for clients.
  3. Using the nursing process is a way of legitimizing our profession and placing us on an equal footing with the pure sciences.
  4. The nursing process is a unidimensional, static, linear approach used to guide us as we make clinical judgments.
